In this study we investigated the variation in number, shape, size and germination mode of ascospores in\ Morchella galilaea, the only species of the genus\ Morchella\ known to fruit in the autumn. Based on the observation of five samples, we first discovered significant variation in the shape and size of ascospores in\ Morchella. One to sixteen ascospores were found in the asci. Ascospore size correlated negatively with ascospore number, but positively with ascus size, and ascus size was positively correlated with ascospore number. We noted that ascospores, both from fresh collections and dried specimens, germinated terminally or laterally either by extended germ tubes, or via the production of conidia that were formed directly from ascospores at one, two or multiple sites. The direct formation of conidia from ascospores takes place within asci or after ascospores are discharged. Using laser confocal microscopy, we recorded the number of nuclei in ascospores and in conidia produced from ascospores. In most ascospores of\ M. galilaea, several nuclei were observed, as is typical of species of\ Morchella. However, nuclear number varied from zero to around 20 in this species, and larger ascospores harbored more nuclei. One to six nuclei were present in the conidia. Nuclear migration from ascospores to conidia was observed. Conidia forming directly from ascospores has been observed in few species of Pezizomycetes; this is the first report of the phenomenon in\ Morchella\ species. Morphological and molecular data show that conidial formation from ascospores is not found in all the specimens of this species and, hence, is not an informative taxonomic character in\ M. galilaea. Our data suggest that conidia produced from ascospores and successive mitosis within the ascus may contribute to asci with more than eight spores. The absence of mitosis and/or nuclear degeneration, as well as cytokinesis defect, likely results in asci with fewer than eight ascospores.

The question posed is whether there is a single widespread powdery mildew species,\ E. alphitoides,\ or an assemblage of closely allied species. To answer this question, specimens of related recognized species, particularly those from Japan, have been subjected to phylogenetic multilocus examinations, including\ CAM,\ GAPDH,\ GS, ITS + 28S,\ RPB2, and\ TUB\ sequences. An analysis of the concatenated sequences resulted in the confirmation of several distinct species.

Our present interpretation of sequestrate morphologies, in light of Stephen Jay Gould{\textquoteright}s characterization of neoteny (retention of juvenile features in an adult stage with mature reproductive structures) and progenesis (the onset of sexual maturity in a morphologically immature stage that does not reach the mature morphology observed in the ancestral form), both involved in paedomorphosis, implies that the origin of sequestrate basidiomes might constitute two distinct evolutionary processes.

Along with the Orbiliomycetes, the class represents one of the basal lineages among the filamentous Ascomycota (Shen et al., 2020). The class is thought to have originated between 400 and 540 mya (Beimforde et al., 2014; Martin et al., 2010; Murat et al., 2018). The full diversity of the order has yet to be completely documented since previously undetected lineages continue to be found through application of molecular methods. There are approximately 200 genera and perhaps 2000 species. Ascomata are epigeous (above ground), or hypogeous (below ground). The truffles of commerce belong to this latter group. The epigeous ascomata are apotl1ecial, deistothecial or are highly reduced. The reduced forms are composed of only a few asci in dusters on vegetative hyphae with little or no sterile supporting tissue ( excipulum). In the ep,lppigeous lineages, ascospores are generally forcibly released by an opening at the ascus apex resulting in the formation of an operculum, or lid. Hypogeous members occur in several of the families. There are at least 30 independent origins of truffle-like members (Alvarado et al., 2011, 2016; Cabera et al., 2016; Grupe et al., 2019; llansen et al., 2013; Kraisitu-domsook et al., 2019; Kumar et al., 2017; Laessoe and Hansen, 2007; Smith, 2014; Smith and Healy, 2009; Trappe et al., 2010)}, author = {Pfister, D.H. and Healy, R.

Studies of\ Trochila\ (Leotiomycetes,\ Helotiales,\ Cenangiaceae) are scarce. Here, we describe two new species based on molecular phylogenetic data and morphology.\ Trochila\ bostonensis\ was collected at the Boston Harbor Islands National Recreation Area, Massachusetts. It was found on the stem of\ Asclepias\ syriaca, representing the first report of any\ Trochila\ species from a plant host in the family\ Apocynaceae.\ Trochila\ urediniophila\ is associated with the uredinia of the rust fungus\ Cerotelium\ fici. It was discovered during a survey for rust hyperparasites conducted at the Arthur Fungarium, in a single sample from 1912 collected in Trinidad. Macro- and micromorphological descriptions, illustrations, and molecular phylogenetic analyses are presented. The two new species are placed in\ Trochila\ with high support in both our six-locus (SSU,\ ITS,\ LSU,\ rpb1,\ rpb2,\ tef1) and two-locus (ITS,\ LSU) phylogenetic reconstructions. In addition, two species are combined in\ Trochila:\ Trochila\ colensoi\ (formerly placed in\ Pseudopeziza) and\ T.\ xishuangbanna\ (originally described as the only species in\ Calycellinopsis). This study reveals new host plant families, a new ecological strategy, and a new country record for the genus\ Trochila. Finally, our work emphasizes the importance of specimens deposited in biological collections such as fungaria.

The cryptic lifestyle of most fungi necessitates molecular identification of the guild in environmental studies. Over the past decades, rapid development and affordability of molecular tools have tremendously improved insights of the fungal diversity in all ecosystems and habitats. Yet, in spite of the progress of molecular methods, knowledge about functional properties of the fungal taxa is vague and interpretation of environmental studies in an ecologically meaningful manner remains challenging. In order to facilitate functional assignments and ecological interpretation of environmental studies we introduce a user friendly traits and character database FungalTraits operating at genus and species hypothesis levels. Combining the information from previous efforts such as FUNGuild and FunFun together with involvement of expert knowledge, we reannotated 10,210 and 151 fungal and Stramenopila genera, respectively. This resulted in a stand-alone spreadsheet dataset covering 17 lifestyle related traits of fungal and Stramenopila genera, designed for rapid functional assignments of environmental studies. In order to assign the trait states to fungal species hypotheses, the scientific community of experts manually categorised and assigned available trait information to 697,413 fungal ITS sequences. On the basis of those sequences we were able to summarise trait and host information into 92,623 fungal species hypotheses at 1\% dissimilarity threshold.

The historical misperceptions resulted from the extraordinary morphological features of these oddly constructed ectoparasitic fungi. More recently, molecular phylogenetic studies, in combination with a better understanding of life histories, have clearly placed these fungi among filamentous Ascomycota (subphylum Pezizomycotina).

In the here presented circumscription, which follows the current usage,\ O. xanthostigma\ is among the most frequently recorded species of the genus, whereas\ O. leucostigma\ appears to be much less common. Both grow gregariously on decorticated hygric gymno- and angiosperm wood or rarely bark and show a worldwide distribution.

Except for apothecial colour, there are no other notable morphological differences between them, either in the teleomorph (asci, ascospores, paraphyses) or anamorph (conidiophores, conidia).

Although some biologists correctly interpreted these arthropod ectoparasites as fungi, even ascomycetes, others thought they were worms, red algae, or members of taxa described especially for them. Speculation on the evolution of the group involving red algae, the morphology-based Floridean Hypothesis, persisted deep into the 20th century, in part because valid alternatives were not presented. Although the distinctive features of Laboulbeniales clearly set them apart from other fungi, the difficulty was in the absence of characters grouping them among the fungi. Thaxter considered the Laboulbeniales to be ascomycetes, but he avoided phylogenetic discussions involved in the Floridean Hypothesis all of his life. Eventually, developmental studies of the life history of\ Pyxidiophora\ species, hyphal perithecial ascomycetes with 2-celled ascospores, revealed characters connecting Laboulbeniales to other ascomycetes. The distinctive morphological features of Laboulbeniales (absence of mycelium, a thallus developed from 2-celled ascospores by cell divisions in several planes, arthropod parasitism) can be best understood by comparison with\ Pyxidiophora. The development of a 3-dimensional thallus composed of true parenchyma occurs not only in Laboulbeniales, but also in\ Pyxidiophora\ species.

Resinicolous fungi constitute a heterogeneous assemblage of fungi that live on fresh and solidified plant resins. The genus\ Sarea\ includes, according to current knowledge, two species,\ S. resinae\ and\ S. difformis. In contrast to other resinicolous discomycetes, which are placed in genera also including non-resinicolous species,\ Sarea\ species only ever fruit on resin. The taxonomic classification of\ Sarea\ has proven to be difficult and currently the genus, provisionally and based only on morphological features, has been assigned to the\ Trapeliales\ (Lecanoromycetes). In contrast, molecular studies have noted a possible affinity to the\ Leotiomycetes. Here we review the taxonomic placement of\ Sarea\ using sequence data from seven phylogenetically informative DNA regions including ribosomal (ITS, nucSSU, mtSSU, nucLSU) and protein-coding (rpb1,\ rpb2,\ mcm7) regions.

We combined available and new sequence data with sequences from major\ Pezizomycotina\ classes, especially\ Lecanoromycetes\ and\ Leotiomycetes, and assembled three different taxon samplings in order to place the genus\ Sarea\ within the\ Pezizomycotina. Based on our data, none of the applied phylogenetic approaches (Bayesian Inference, Maximum Likelihood and Maximum Parsimony) supported the placement of\ Sarea\ in the\ Trapeliales\ or any other order in the\ Lecanoromycetes. A placement of\ Sarea\ within the\ Leotiomycetes\ is similarly unsupported. Based on our data, Sarea forms an isolated and highly supported phylogenetic lineage within the "Leotiomyceta". From the results of our multilocus phylogenetic analyses we propose here a new class, order, and family,\ Sareomycetes,\ Sareales\ and\ Sareaceae\ in the\ Ascomycota\ to accommodate the genus\ Sarea. The genetic variability within the newly proposed class suggests that it is a larger group that requires further infrageneric classification.

Comparisons of ITS rDNA sequences of a paratype and two recent collections of G. guanacastensis with published ITS sequences of G. salmonicolor, from the Dominican Republic, show that these are nearly identical. When G. salmonicolor was erected no sequences of the type species were available. Morphological comparisons supports the conspecificity. Details regarding the description of G. salmonicolor are pointed out. A four-gene phylogeny places Geodina and Wynnea as a supported sister group to the rest of the Sarcoscyphaceae. Species in these genera share morphological traits of cyanophobic spore markings, dark angular outer excipular cells that give rise to hairs and the origin of several apothecia from a common basal stalk. Their occurrence on soil rather than on wood or plant material distinguish them from other Sarcoscyphaceae. Based on morphology, phylogenic relationships and trophic interactions we erect a new family, Wynneaceae, for Geodina and Wynnea.

Little is known about the diversity of Orbiliomycetes from Puerto Rico. Cantrell \& Lodge (2008) compiled a list of the fungi from Puerto Rico, and only mentioned four species of Orbilia: O. andina, O. chysocoma, O. delicata and O. cf. gaillardii. During IMC11 in Puerto Rico, 2018, several collections of Orbiliomycetes were found in Juan Enrique Monagas Park during the Ascomycete workshop field trip. Some of these were sent to the Cornell and Farlow Herbaria. One collection caught the attention of Luis Quijada due to its interesting morphological features. This species is not related to any of the species reported by Cantrell \& Lodge (2008). The morphology of the asci and ascospores of the sexual morph clearly indicates a relationship with Orbilia auricolor and related species (section Arthrobotrys). The morphology of the strongly mammiform paraphyses and the excipulum with large cortical cells with knob-like glassy caps had never before seen in this section. Our cultures produced an Arthrobotrys-like anamorph most similar to the anamorph of O. blumenaviensis (= A. vermicola), but the conidia are distinctly smaller and never more than 1-septate. Molecular data supports the placement of this Orbilia in series Arthrobotrys. Species in this series produce adhesive networks as trapping organs in the presence of nematodes, and this behavior was confirmed in cultures of this Orbilia. Our phylogenetic analysis shows this species as very distinct from O. blumenaviensis and supports it being new to science.

The harvesting of morels is a vital economic activity for local communities in Chile because they are a significant commercial export for the country. Although many species of morels produce ascomata in the absence of fire, abundant ascomata production occurs among some Morchella species when triggered by fire. The intentional burning of Nothofagus forests in Southern Chile, as a means to increase morel production, has become a problem and has negatively impacted ecosystems. Information on the distribution of morels in South America is limited. Spegazzini (1909) described M. patagonica from Argentina and Gamundi et al. (2004) listed five Morchella species from Patagonia and surrounding areas including Spegazzini{\textquoteright}s species. Recently Pildain et al. (2014) and Baroni et al. (2018) have examined diversity of Morchella species in South America and the Caribbean using molecular methods. To better understand which Morchella species are being commercially harvested in Southern Chile, molecular markers were used to identify collections of morels being harvested and/or sold commercially and determine their phylogenetic relationships. Morels were sampled from collections in the Fungarium of the Fundaci{\'o}n Fungi, Chile (FFCL) and batches purchased from commercial harvesters and bulk gatherers in 2015 and 2016. DNA sequence from the EF1a, RPB1, ITS and RPB2 were obtained and used for phylogenetic analyses. This study will contribute to the knowledge of morels in South America and help to understand their phylogenetic relationships with other Morchella species found worldwide.

Fungi in the class\ Leotiomycetes\ are ecologically diverse, including mycorrhizas, endophytes of roots and leaves, plant pathogens, aquatic and aero-aquatic hyphomycetes, mammalian pathogens, and saprobes. These fungi are commonly detected in cultures from diseased tissue and from environmental DNA extracts. The identification of specimens from such character-poor samples increasingly relies on DNA sequencing. However, the current classification of\ Leotiomycetes\ is still largely based on morphologically defined taxa, especially at higher taxonomic levels. Consequently, the formal\ Leotiomycetes\ classification is frequently poorly congruent with the relationships suggested by DNA sequencing studies. Previous class-wide phylogenies of\ Leotiomycetes\ have been based on ribosomal DNA markers, with most of the published multi-gene studies being focussed on particular genera or families. In this paper we collate data available from specimens representing both sexual and asexual morphs from across the genetic breadth of the class, with a focus on generic type species, to present a phylogeny based on up to 15 concatenated genes across 279 specimens. Included in the dataset are genes that were extracted from 72 of the genomes available for the class, including 10 new genomes released with this study. To test the statistical support for the deepest branches in the phylogeny, an additional phylogeny based on 3156 genes from 51 selected genomes is also presented. To fill some of the taxonomic gaps in the 15-gene phylogeny, we further present an ITS gene tree, particularly targeting ex-type specimens of generic type species.

The formal taxonomic changes are limited in part because of the ad hoc nature of taxon and specimen selection, based purely on the availability of data. The phylogeny constitutes a framework for enabling future taxonomically targeted studies using deliberate specimen selection. Such studies will ideally include designation of epitypes for the type species of those genera for which DNA is not able to be extracted from the original type specimen, and consideration of morphological characters whenever genetically defined clades are recognized as formal taxa within a classification.

Triblidiaceae is a family of uncommonly encountered, non-lichenized discomycetes. A recent classification circumscribed the family to include Triblidium (4 spp. and 1 subsp.), Huangshania (2 spp.) and Pseudographis (2 spp. and 1 var.). The apothecia of these fungi are persistent and drought-tolerant; they possess stromatic, highly melanized covering layers that open and close with fluctuations of humidity. Triblidialean fungi occur primarily on the bark of Quercus, Pinaceae and Ericaceae, presumably as saprobes. Though the type species of Huangshania is from China, these fungi are mostly known from collections originating from Western Hemisphere temperate and boreal forests. The higher-rank classification of triblidialean fungi has been in flux due in part to an overemphasis on ascospore morphology. Muriform ascospores are observed in species of Triblidium and in Pseudographis elatina. An intense, dark blue/purple ascospore wall reaction in iodine-based reagents is observed in species of Pseudographis. These morphologies have led, in part, to these genera being shuffled among unrelated taxa in Hysteriaceae (Dothideomycetes, Hysteriales) and Graphidaceae (Lecanoromycetes, Ostropales). Triblidiaceae has been placed within the monofamilial order Triblidiales (affinity Lecanoromycetes). Here, we demonstrate with a three-gene phylogenetic approach that triblidialean fungi are related to taxa in Rhytismatales (Leotiomycetes). We synonymize Triblidiales under Rhytismatales and emend Triblidiaceae to include Triblidium and Huangshania, with Pseudographis placed within Rhytismataceae. A history of Triblidiaceae is provided along with a description of the emended family. We discuss how the inclusion of triblidialean fungi in Rhytismatales brings some rarely observed or even unique ascospore morphologies to the order and to Leotiomycetes.

Abstract: Species of the genus Wynnea are collected in association with a subterranean mass generally referred to as a sclerotium.

This is one of the few genera of the Sarcoscyphaceae not associated with plant material {\textendash} wood or leaves. The sclerotium is

composed of hyphae of both Armillaria species and Wynnea species. To verify the existence of Armillaria species in the sclerotia of

those Wynnea species not previously examined and to fully understand the structure and nature of the sclerotium, molecular data

and morphological characters were analyzed. Using nuclear ITS rDNA sequences the Armillaria species co-occurring with Wynnea

species were identified from all examined material. These Armillaria symbionts fall into two main Armillaria groups {\textendash} the A. gallicanabsnona-

calvescens group and the A. mellea group. Divergent time estimates of the Armillaria and Wynnea lineages support a

co-evolutionary relationship between these two fungi.

It is increasingly appreciated that plant microbiomes can influence these aspects of plant biology, but little is known regarding the historic distribution of microbes associated with plants collected in the pre-molecular age. If microbiomes can be observed reliably in herbarium specimens, researchers will gain a new lens with which to examine microbial ecology, evolution, species interactions. Here, we describe a method for accessing historical plant microbiomes from preserved herbarium specimens, providing a proof of concept using two plant taxa from the imperiled boreal biome (Andromeda polifolia\ and\ Ledum palustre\ subsp. groenlandicum,\ Ericaceae). We focus on fungal endophytes, which occur within symptomless plant tissues such as leaves. Through a three-part approach (i.e. culturing, cloning and next-generation amplicon sequencing via the Illumina MiSeq platform, with extensive controls), we examined endophyte communities in dried, pressed leaves that had been processed as regular herbarium specimens and stored at room temperature in a herbarium for four years.\ We retrieved only one endophyte in culture, but cloning and especially the MiSeq analysis revealed a rich community of foliar endophytes. The phylogenetic distribution and diversity of endophyte assemblages, especially among the Ascomycota, resemble endophyte communities from fresh plants collected in the boreal biome. We could distinguish communities of endophytes in each plant species and differentiate likely endophytes from fungi that could be surface contaminants. Taxa found by cloning were observed in the larger MiSeq dataset, but species richness was greater when subsets of the same tissues were evaluated with the MiSeq approach. Our findings provide a proof of concept for capturing endophyte DNA from herbarium specimens, supporting the importance of herbarium records as roadmaps for understanding the dynamics of plant-associated microbial biodiversity in the Anthropocene.This article is part of the theme issue {\textquoteright}Biological collections for understanding biodiversity in the Anthropocene{\textquoteright}.}, author = {Barnabas H.

First published by Fries in 1825, the genus Sarea today comprises two accepted species of resinicolous discomycetes. Both species have a very broad range, with S. difformis reported from North America, Europe, and northwestern Africa, and S. resinae reported from North America, Europe, northern and central Africa, and central and eastern Asia. Both species have also been reported in southern hemisphere locations, such as New Zealand, on non-native trees. Both species also have a broad range of hosts in the Pinaceae, with S. difformis reported on Cedrus atlantica and both Sarea species reported on species of Pinus, Picea, Larix, Pseudotsuga, Abies and Tsuga. In addition, S. resinae has been reported on species in the Cupressaceae, including members of the genera Cupressus, Chamaecyparis, Juniperus and Taxodium. With few exceptions, specimens of each Sarea species share a very similar macro- and micromorphology, with specimens from multiple hosts fitting the specific concepts published by Hawksworth and Sherwood in 1981. Some molecular work has been done on the genus, but in almost all cases sequences are not associated with a vouchered herbarium specimen including the sexual morph. The objective of this study is to determine the degree of relatedness of geographically distant specimens collected in North America, Europe, and Macaronesia on different native and non-native host species. With permission, collections have been made of both species of Sarea from California, Georgia and the New England states in the USA, Northern and Southern Europe and Macaronesia. In addition to detailed measurements of the micromorphological features of specimens, ITS and LSU sequences have been generated using Sanger sequencing for analysis and comparison with published sequences. In contrast to the generally only slight morphological differences noted among specimens, ITS sequences from Europe, Asia, and North America not only differ by about 4\% from each other, but also when submitted to phylogenetic analyses form multiple well-supported clades for each continent. These patterns are supported by similar analyses using the LSU sequences and ITS+LSU sequences. These clades also point to host specificity at the host family or genus level. In conclusion, the composition of the genus Sarea seems much more complicated than previously reported, with the possibility of multiple cryptic species in both accepted taxa; additional work must be done to further expand geographical and host range sampling of specimens to include in these analyses in order to approach a full picture of the diversity in Sarea.

Truffle species within the /tarzetta-geopyxis lineage share smooth, globose, hyaline spores, but differ in the amount of convolution of hymenia in ascomata.

He used the potato to investigate questions of what a species is, understand its ravages by a plant pathogen, and investigate ideas on clonal versus sexual reproduction on species fitness. Darwin{\textquoteright}s letters reveal his thoughts on free trade, population growth and food security during the Irish famine. Darwin was involved in the first research to find resistance to late blight and personally funded a breeding program in Ireland.

Hesperomyces virescens is a fungal ectoparasite (Laboulbeniales) that infects adult ladybirds. Research has recently focused on this parasite due to the discovery of its prevalence on the globally invasive harlequin ladybird Harmonia axyridis and for its potential use in studies of co-evolution and pathogen spread. We collected adults from ten species of ladybirds in the Western Cape Province, South Africa, and screened for the presence of H. virescens. Infections with H. virescens were found in the samples of two species, H. axyridis and the native Cheilomenes propinqua. This marks the first record of H. virescens on H. axyridis from the African continent and the first record on Cheilomenes worldwide.

The harlequin ladybird, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), is native to Asia but has been intentionally introduced to many countries as a biological control agent of pest insects. In numerous countries, however, it has been introduced unintentionally. The dramatic spread of H. axyridis within many countries has been met with considerable trepidation. It is a generalist top predator, able to thrive in many habitats and across wide climatic conditions. It poses a threat to biodiversity, particularly aphidophagous insects, through competition and predation, and in many countries adverse effects have been reported on other species, particularly coccinellids. However, the patterns are not consistent around the world and seem to be affected by many factors including landscape and climate. Research on H. axyridis has provided detailed insights into invasion biology from broad patterns and processes to approaches in surveillance and monitoring. An impressive number of studies on this alien species have provided mechanistic evidence alongside models explaining large-scale patterns and processes. The involvement of citizens in monitoring this species in a number of countries around the world is inspiring and has provided data on scales that would be otherwise unachievable. Harmonia axyridis has successfully been used as a model invasive alien species and has been the inspiration for global collaborations at various scales. There is considerable scope to expand the research and associated collaborations, particularly to increase the breadth of parallel studies conducted in the native and invaded regions. Indeed a qualitative comparison of biological traits across the native and invaded range suggests that there are differences which ultimately could influence the population dynamics of this invader. Here we provide an overview of the invasion history and ecology of H. axyridis globally with consideration of future research perspectives. We reflect broadly on the contributions of such research to our understanding of invasion biology while also informing policy and people.

Background - Laboulbeniales (Fungi, Ascomycota) are microscopic ectoparasites of Arthropoda. Since many Laboulbeniales are known to be host-specific, wet tropical areas with high arthropod diversity are likely to house a high diversity of Laboulbeniales, as well. In this paper, we reveal the presence of the genus Diphymyces I.I.Tav. in Malaysian Borneo. After fieldwork in disturbed and pristine tropical rainforest in Borneo, representatives of this genus were discovered that did not match the description of any of the fourteen known species.Methods - Insects were collected with dry pitfall traps baited with Limburger cheese. Fungal material was studied and described using morphology-based methods.Key results - A new species, Diphymyces sabahensis Haelew. \& Pfister, is described and illustrated. Hosts for this species are recently described taxa in Ptomaphaginus Portevin, 1914 (Coleoptera, Leiodidae, Cholevinae, Ptomaphagini), representing a new host genus for Diphymyces. Other, morphologically distinctive records of Diphymyces were found; on one host specimen they co-occur with D. sabahensis. These divergent thalli are remarkable in their restricted occurrence on the metatibiae, and thus may represent a morphological variant of D. sabahensis. A review of all described species of Diphymyces, with hosts and geographical distribution, is also presented in tabulated form.

The family Cudoniaceae (Rhytismatales, Ascomycota) was erected to accommodate the "earth tongue fungi" in the genera Cudonia and Spathularia. There have been no recent taxonomic studies of these genera, and the evolutionary relationships within and among these fungi are largely unknown. Here we explore the molecular phylogenetic relationships within Cudonia and Spathularia using maximum likelihood and Bayesian inference analyses based on 111 collections from across the Northern Hemisphere. Phylogenies based on the combined data from ITS, nrLSU, rpb2 and tef-1 alpha sequences support the monophyly of three main clades, the /flavida, /velutipes, and /cudonia clades. The genus Cudonia and the family Cudoniaceae are supported as monophyletic groups, while the genus Spathularia is not monophyletic. Although Cudoniaceae is monophyletic, our analyses agree with previous studies that this family is nested within the Rhytismataceae. Our phylogenetic analyses circumscribes 32 species-level clades, including the putative recognition of 23 undescribed phylogenetic species. Our molecular phylogeny also revealed an unexpectedly high species diversity of Cudonia and Spathularia in eastern Asia, with 16 (out of 21) species-level clades of Cudonia and 8 (out of 11) species-level clades of Spathularia. We estimate that the divergence time of the Cudoniaceae was in the Paleogene approximately 28 Million years ago (Mya) and that the ancestral area for this group of fungi was in Eastern Asia based on the current data. We hypothesize that the large-scale geological and climatic events in Oligocene (e. g. the global cooling and the uplift of the Tibetan plateau) may have triggered evolutionary radiations in this group of fungi in East Asia. This work provides a foundation for future studies on the phylogeny, diversity, and evolution of Cudonia and Spathularia and highlights the need for more molecular studies on collections from Europe and North America.

Angelina rufescens is placed within the core clade of Rhytismatales (Leotiomycetes, Pezizomycotina, Ascomycota) based on analysis of LSU and mtSSU rDNA. The only species in the genus, it produces distinctive ascomata that reoccur annually on wood and on the remains of its own previous fructifications, forming dense conglomerations of interlocking longitudinally elongated apothecia with gray hymenia. Known collections and references of A. rufescens indicate that it is endemic to eastern and central United States. Morphological and cultural characters are described with notes on ascomata development. No mitospores were observed in field collections or in culture. Lectotypes are designated for Hysterium rufescens and its synonym Ascobolus conglomeratus. Angelina rufescens is illustrated here for the first time in the taxonomic literature.

The family Caloscyphaceae with a single genus, Caloscypha, has been considered to include a single species, C. fulgens. Study of an overlooked second species, Caloscypha incarnata from North Africa and Italy, using SSU, LSU rDNA, and morphology allows placement of this species in a new genus, Kallistoskypha, in the Caloscyphaceae. This fungus is found in association with Eucalyptus species. The species was recently redescribed from Spain under the name Marcelleina parvispora. Caloscypha fulgens, the type species of the genus Caloscypha, shows sequence variation from across its range.

Fungal mitospores may function as dispersal units and/ or spermatia and thus play a role in distribution and/or mating of species that produce them. Mitospore production in ectomycorrhizal (EcM) Pezizales is rarely reported, but here we document mitospore production by a high diversity of EcM Pezizales on three continents, in both hemispheres. We sequenced the internal transcribed spacer (ITS) and partial large subunit (LSU) nuclear rDNA from 292 spore mats (visible mitospore clumps) collected in Argentina, Chile, China, Mexico and the USA between 2009 and 2012. We collated spore mat ITS sequences with 105 fruit body and 47 EcM root sequences to generate operational taxonomic units (OTUs). Phylogenetic inferences were made through analyses of both molecular data sets. A total of 48 OTUs from spore mats represented six independent EcM Pezizales lineages and included truffles and cup fungi. Three clades of seven OTUs have no known meiospore stage. Mitospores failed to germinate on sterile media, or form ectomycorrhizas on Quercus, Pinus and Populus seedlings, consistent with a hypothesized role of spermatia. The broad geographic range, high frequency and phylogenetic diversity of spore mats produced by EcM Pezizales suggests that a mitospore stage is important for many species in this group in terms of mating, reproduction and/or dispersal.

Truffles have evolved from epigeous (aboveground) ancestors in nearly every major lineage of fleshy fungi. Because accelerated rates of morphological evolution accompany the transition to the truffle form, closely related epigeous ancestors remain unknown for most truffle lineages. This is the case for the quintessential truffle genus Tuber, which includes species with socio-economic importance and esteemed culinary attributes. Ecologically, Tuber spp. form obligate mycorrhizal symbioses with diverse species of plant hosts including pines, oaks, poplars, orchids, and commercially important trees such as hazelnut and pecan. Unfortunately, limited geographic sampling and inconclusive phylogenetic relationships have obscured our understanding of their origin, biogeography, and diversification. To address this problem, we present a global sampling of Tuberaceae based on DNA sequence data from four loci for phylogenetic inference and molecular dating. Our well-resolved Tuberaceae phylogeny shows high levels of regional and continental endemism. We also identify a previously unknown epigeous member of the Tuberaceae - the South American cup-fungus Nothojafnea thaxteri (E.K. Cash) Gamundi. Phylogenetic resolution was further improved through the inclusion of a previously unrecognized Southern hemisphere sister group of the Tuberaceae. This morphologically diverse assemblage of species includes truffle (e.g. Gymnohydnotrya spp.) and non-truffle forms that are endemic to Australia and South America. Southern hemisphere taxa appear to have diverged more recently than the Northern hemisphere lineages. Our analysis of the Tuberaceae suggests that Tuber evolved from an epigeous ancestor. Molecular dating estimates Tuberaceae divergence in the late Jurassic (similar to 156 million years ago), with subsequent radiations in the Cretaceous and Paleogene. Intra-continental diversification, limited long-distance dispersal, and ecological adaptations help to explain patterns of truffle evolution and biodiversity.

Pyronemataceae is the largest and most heterogeneous family of Pezizomycetes. It is morphologically and ecologically highly diverse, comprising saprobic, ectomycorrhizal, bryosymbiotic and parasitic species, occurring in a broad range of habitats (on soil, burnt ground, debris, wood, dung and inside living bryophytes, plants and lichens). To assess the monophyly of Pyronemataceae and provide a phylogenetic hypothesis of the group, we compiled a four-gene dataset including one nuclear ribosomal and three protein-coding genes for 132 distinct Pezizomycetes species (4437 nucleotides with all markers available for 80\% of the total 142 included taxa). This is the most comprehensive molecular phylogeny of Pyronemataceae, and Pezizomycetes, to date. Three hundred ninety-four new sequences were generated during this project, with the following numbers for each gene: RPB1 (124), RPB2 (99), EF-1 alpha (120) and LSU rDNA (51). The dataset includes 93 unique species from 40 genera of Pyronemataceae, and 34 species from 25 genera representing an additional 12 families of the class. Parsimony, maximum likelihood and Bayesian analyses suggest that Pyronemataceae is paraphyletic due to the nesting of both Ascodesmidaceae and Glaziellaceae within the family. Four lineages with taxa currently classified in the family, the Boubovia, Geopyxis, Pseudombrophila and Pulvinula lineages, form a monophyletic group with Ascodesmidaceae and Glaziellaceae. We advocate the exclusion of these four lineages in order to recognize a monophyletic Pyronemataceae. The genus Coprotus (Thelebolales, Leotiomycetes) is shown to belong to Pezizomycetes, forming a strongly supported monophyletic group with Boubovia. Ten strongly supported lineages are identified within Pyronemataceae s. str. Of these, the Pyropyxis and Otidea lineages are identified as successive sister lineages to the rest of Pyronemataceae s. str. The highly reduced (gymnohymenial) Monascella is shown to belong to Pezizomycetes and is for the first time suggested to be closely related to the cleistothecial Warcupia, as a sister group to the primarily apothecial Otidea. None of the lineages of pyronemataceous taxa identified here correspond to previous families or subfamily classifications. Ancestral character state reconstructions (ASR) using a Bayesian approach support that the ancestors of Pezizomycetes and Pyronemataceae were soil inhabiting and saprobic. Ectomycorrhizae have arisen within both lineages A, B and C of Pezizomycetes and are suggested to have evolved independently seven to eight times within Pyronemataceae s. L, whereas an obligate bryosymbiotic lifestyle has arisen only twice. No reversals to a free-living, saprobic lifestyle have happened from symbiotic or parasitic Pyronemataceae. Specializations to various substrates (e.g. burnt ground and dung) are suggested to have occurred several times in mainly saprobic lineages. Although carotenoids in the apothecia are shown to have arisen at least four times in Pezizomycetes, the ancestor of Pyronemataceae s. str., excluding the Pyropyxis and Otidea lineages, most likely produced carotenoids, which were then subsequently lost in some clades ( and possibly gained again). Excipular hairs were found with a high probability to be absent from apothecia in the deepest nodes of Pezizomycetes and in the ancestor of Pyronemataceae s. str. True hairs are restricted to the core group of Pyronemataceae s. str., but are also found in Lasiobolus (Ascodesmidaceae), the Pseudombrophila lineage and the clade of Chorioactidaceae, Sarcoscyphaceae and Sarcosomataceae. The number of gains and losses of true hairs within Pyronemataceae s. str., however, remains uncertain. The ASR of ascospore guttulation under binary coding (present or absent) indicates that this character is fast evolving and prone to shifts. O 2013 Elsevier Inc. All rights reserved.

Eleven species of the genus Scutellinia (Pyronemataceae, Pezizales) are recognized in Korea by analysis of macro- and micro-morphological characteristics, substrates and geographical distributions. Eight species are recorded new to Korea, namely, S. ahmadiopsis, S. badio-berbis, S. colensoi, S. jilinensis, S. nigrohirtula, S. olivascens, S. setosa and S. patagonica. Based on the exceptional length of marginal hairs and tuberculate ascospore wall ornamentation, two Korean specimens occurring on wood are described as a new species. Infraspecific morphological variations among collections within S. scutellata and S. patagonica were found. These are tentatively treated as species complexes. The highly questionable occurrence of S. setosa in Asia was confirmed. The importance of characteristics of paraphyses for species delimitation is highlighted. Descriptions and taxonomic notes of the recognized species of Scutellinia are provided with a taxonomic key, illustrations and photographs of these species from Korea.

The obligate, biotrophic association among species of the fungal genus Cyttaria and their hosts in the plant genus Nothofagas often is cited as a classic example of cophylogeny and is one of the few cases in which the biogeography of a fungus is commonly mentioned or included in biogeographic analyses. In this study molecular and morphological data are used to examine hypotheses regarding the cophylogeny and biogeography of the 12 species of Cyttaria and their hosts, the 11 species of Nothofagas subgenera Lophozonia and Nothofagus. Our results indicate highly significant overall cophylogenetic structure, despite the fact that the associations between species of Cyttaria and Nothojagus usually do not correspond in a simple one to one relationship. Two major lineages of Cyttaria are confined to a single Nothofagus subgenus, a specificity that might. account for a minimum of two codivergences. We hypothesize other major codivergences. Numerous extinction also are assumed, as are an independent. parasite divergence followed by host switching to account for C. berteroi. Considering the historical association of Cyttaria and Nothofagus, our hypothesis may support the vicariance hypothesis for the trans-Antarctic distribution between Australasian and South American species of Cyttaria species hosted by subgenus Lophozonia. It also supports the hypothesis of transoceanic long distance dispersal to account for the relatively recent relationship between Australian and New Zealand Cyttaria species, which we estimate to have occurred 44.6-28.5 mya. Thus the history of these organisms is not only a reflection of the breakup of Gondwana but also of other events that have contributed to the distributions of many other southern hemisphere plants and fungi.

Cyttaria species (Leotiomycetes, Cyttariales) are obligate, biotrophic associates of Nothofagus (Hamamelididae, Nothofagaceae), the southern beech. As such Cyttaria species are restricted to the southern hemisphere, inhabiting southern South America (Argentina and Chile) and southeastern Australasia (southeastern Australia including Tasmania, and New Zealand). The relationship of Cyttaria to other Leotiomycetes and the relationships among species of Cyttaria were investigated with newly generated sequences of partial nucSSU, nucLSU and mitSSU rRNA, as well as TEE] sequence data and morphological data. Results found Cyttaria to be defined as a strongly supported clade. There is evidence for a close relationship between Cyttaria and these members of the Helotiales: Cordierites, certain Encoelia spp., Ionomidotis and to a lesser extent Chlorociboria. Order Cyttariales is supported by molecular data, as well as by the unique endostromatic apothecia, lack of chitin and highly specific habit of Cyttaria species. Twelve Cyttaria species are hypothesized, including all 11 currently accepted species plus an undescribed species that accommodates specimens known in New Zealand by the misapplied name C. gunnii, as revealed by molecular data. Thus the name C. gunnii sensu stricto is reserved for specimens occurring on N. cunninghamii in Australia, including Tasmania. Morphological data now support the continued recognition of C. septentrionalis as a species separate from C. gunnii. Three major clades are identified within Cyttaria: one in South America hosted by subgenus Nothofagus, another in South America hosted by subgenera Nothofagus and Lophozonia, and a third in South America and Australasia hosted by subgenus Lophozonia, thus producing a non-monophyletic grade of South American species and a monophyletic clade of Australasian species, including monophyletic Australian and New Zealand clades. Cyttaria species do not sort into clades according to their associations with subgenera Lophozonia and Nothofagus.

Medeolaria farlowii, an ascomycetous parasite of Medeola virginiana, has been included as the only member of the family Medeolariaceae and order Medeolariales. Its assignment within the Ascomycota has been problematic due to the lack of distinctive ascomatal form and ascus morphology. Asci are formed in a loosely organized hymenium on hypertrophic portions of Medeola virginiana stems. Phylogenetic analyses of nuclear 5.8S, large subunit, and small subunit rDNA gene sequences place M. farlowii in the Leotiomycetes with parsimony, Bayesian, and maximum likelihood analyses, but its position within this class remains unresolved. In general, limited taxon and gene sampling in the Leotiomycetes hampers placement of taxa within this class. A survey of available sequence data in the Leotiomycetes is given, and the implication for phylogenetic studies within the class is discussed. Medeolaria farlowii should be treated as a monotypic genus in the monotypic order Medeolariales, class Leotiomycetes.

We present a 6-gene, 420-species maximum-likelihood phylogeny of Ascomycota, the largest phylum of Fungi. This analysis is the most taxonomically complete to date with species sampled from all 15 currently circumscribed classes. A number of superclass-level nodes that have previously evaded resolution and were unnamed in classifications of the Fungi are resolved for the first time. Based on the 6-gene phylogeny we conducted a phylogenetic informativeness analysis of all 6 genes and a series of ancestral character state reconstructions that focused on morphology of sporocarps, ascus dehiscence, and evolution of nutritional modes and ecologies. A gene-by-gene assessment of phylogenetic informativeness yielded higher levels of informativeness for protein genes (RPB1, RPB2, and TEF1) as compared with the ribosomal genes, which have been the standard bearer in fungal systematics. Our reconstruction of sporocarp characters is consistent with 2 origins for multicellular sexual reproductive structures in Ascomycota, once in the common ancestor of Pezizomycotina and once in the common ancestor of Neolectomycetes. This first report of dual origins of ascomycete sporocarps highlights the complicated nature of assessing homology of morphological traits across Fungi. Furthermore, ancestral reconstruction supports an open sporocarp with an exposed hymenium (apothecium) as the primitive morphology for Pezizomycotina with multiple derivations of the partially (perithecia) or completely enclosed (cleistothecia) sporocarps. Ascus dehiscence is most informative at the class level within Pezizomycotina with most superclass nodes reconstructed equivocally. Character-state reconstructions support a terrestrial, saprobic ecology as ancestral. In contrast to previous studies, these analyses support multiple origins of lichenization events with the loss of lichenization as less frequent and limited to terminal, closely related species.

Dating of fungal divergences with molecular clocks thus far has yielded highly inconsistent results. The origin of fungi was estimated at between 660 million and up to 2.15 billion y ago, and the divergence of the two major lineages of higher Fungi, Ascomycota and Basidiomycota, at between 390 million y and LIP to 1.5 billion y ago. Assuming that these inconsistencies stein from various causes, we reassessed the systematic placement of the most important fungal fossil, Paleopyrenomycites, and recalibrated internally unconstrained, published molecular clock trees by applying uniform calibration points. As a result the origin of fungi was re-estimated at between 760 million and 1.06 billion y ago and the origin of the Ascomycota at 500-650 million y ago. These dates are much more consistent than previous estimates, even if based on the same phylogenies and molecular clock trees, and they are also much better in line with the fossil record of fungi and plants and the ecological interdependence between filamentous fungi and land plants. Our results do not provide evidence to suggest the existence of ancient protolichens as an alternative to explain the ecology of early terrestrial fungi in the absence of land plants.

Tuberculate ectomycorrhizae (TECM) are unique structures in which aggregates of ectomycorrhizal roots are encased in a covering of fungal hyphae. The function of TECM is unknown, but they probably enhance the nitrogen nutrition and disease resistance of host plants. Trees in the Pinaceae form TECM with species of Rhizopogon and Suillus (Suillineae, Boletales). Similar tubercules are found with diverse angiosperms, but their mycobionts have not been phylogenetically characterized. We collected TECM in Mexico and the USA that were similar to TECM in previous reports. We describe these TECM and identify both the plant and fungal symbionts. Plant DNA confirms that TECM hosts are Quercus species. ITS sequences from tubercules and sclerotia (hyphal aggregations that serve as survival structures) matched sporocarps of Boletus rubropunctus. Phylogenetic analyses confirm that this fungus belongs to the suborder Boletineae (Boletales). This is the first published report of TECM formation in the Boletineae and of sclerotia formation by a Boletus species. Our data suggest that the TECM morphology is all adaptive feature that has evolved separately in two suborders of Boletales (Suillineae and Boletineae) and that TECM formation is controlled by the mycobiont because TECM are found on distantly related angiosperm and gymnosperm host plants.

Chaetothiersia vernalis, collected from the northern High Sierra Nevada of California, is described as a new genus and species. This fungus is characterized by stiff, superficial, brown excipular hairs, smooth, eguttulate ascospores, and a thin ectal excipulum composed of globose to angular-globose cells. Phylogenetic analyses of nLSU rDNA sequence data support the recognition of Chaetothiersia as a distinct genus, and suggest a close relationship to the genus Paratrichophaea.

Molecular phylogenetic and comparative morphological studies provide evidence for the recognition of a new family, Chorioactidaceae, in the Pezizales. Four genera are placed in the family: Chorioactis, Desmazierella, Neournula, and Wolfina. Based on parsimony, likelihood, and Bayesian analyses of LSU, SSU, and RPB2 sequence data, Chorioactidaceae represents a sister clade to the Sarcosomataceae, to which some of these taxa were previously referred. Morphologically these genera are similar in pigmentation, excipular construction, and asci, which mostly have terminal opercula and rounded, sometimes forked, bases without croziers. Ascospores have cyanophilic walls or cyanophilic surface ornamentation in the form of ridges or warts. So far as is known the ascospores and the cells of the paraphyses of all species are multinucleate. The six species recognized in these four genera all have limited geographical distributions in the northern hemisphere. (c) 2007 The British Mycological Society. Published by Elsevier Ltd.

Partial sequences of nuLSU rDNA were obtained to investigate the phylogenetic relationships of Pyronemataceae, the largest and least studied family of Pezizales. The dataset includes sequences for 162 species from 51 genera of Pyronemataceae, and 39 species from an additional 13 families of Pezizales. Parsimony, ML, and Bayesian analyses suggest that Pyronemataceae is not monophyletic as it is currently circumscribed. Ascodesmidaceae is nested within Pyronemataceue, and several pyronernataceous taxa are resolved outside the family. Glaziellaceae forms the sister group to Pyronemataceae in ML analyses, but this relationship, as well as those of Pyronemataceae to the other members of the lineage, are not resolved with support. Fourteen clades of pyronernataceous taxa are well supported and/or present in all recovered trees. Several pyronemataceous genera are suggested to be non-monophyletic, including Anthracobia, Cheilymenia, Geopyxis, Humaria, Lasiobolidium, Neottiella, Octospora, Pulvinula, Stephensia, Tricharina, and Trichophaea. Cleistothecial and truffle or truffle-like ascomata forms appear to have evolved independently multiple times within Pyronemataceae. Results of these analyses do not support previous classifications of Pyronemataceae, and suggest that morphological characters traditionally used to segregate the family into subfamilial groups are not phylogenetically informative above the genus level.

Plant species in the subfamily Monotropoideae are mycoheterotrophs; they obtain fixed carbon from photosynthetic plants via a shared mycorrhizal network. Previous findings show mycoheterotrophic plants exhibit a high level of specificity to their mycorrhizal fungi. In this study we explore the association of mycorrhizal fungi and Monotropa uniflora (Mono tropoideae: Ericaceae) in eastern North America. We collected M. uniflora roots and nearby basidiomycete sporocarps from four sites within a 100 km(2) area in eastern Massachusetts. We analyzed DNA sequences of the internal transcribed spacer region (ITS) from the fungal nuclear ribosomal gene to assess the genetic diversity of fungi associating with M. uniflora roots. In this analysis we included 20 ITS sequences from Russula sporocarps collected nearby, 44 sequences of Russula or Lactarius species from GenBank and 12 GenBank sequences of fungi isolated from M. uniflora roots in previous studies. We found that all 56 sampled M. uniflora mycorrhizal fungi were members of the Russulaceae, confirming previous research. The analysis showed that most of the diversity of mycorrhizal fungi spreads across the genus Russula. ITS sequences of the mycorrhizal fungi consisted of 20 different phylotypes: 18 of the genus Russula and two of Lactafius, based on GenBank searches. Of the sampled plants, 57\% associated with only three of the 20 mycorrhizal fungi detected in roots, and of the 25 sporocarp phylotypes collected three, were associated with M. uniflara. Furthermore the results indicate that the number of different fungal phylotypes associating with M. uniflora of eastern North America is higher than that of western North America but patterns of fungal species abundance might be similar between mycorrhizae from the two locations.

The ancestors of fungi are believed to be simple aquatic forms with flagellated spores, similar to members of the extant phylum Chytridiomycota (chytrids). Current classifications assume that chytrids form an early-diverging clade within the kingdom Fungi and imply a single loss of the spore flagellum, leading to the diversification of terrestrial fungi. Here we develop phylogenetic hypotheses for Fungi using data from six gene regions and nearly 200 species. Our results indicate that there may have been at least four independent losses of the flagellum in the kingdom Fungi. These losses of swimming spores coincided with the evolution of new mechanisms of spore dispersal, such as aerial dispersal in mycelial groups and polar tube eversion in the microsporidia ( unicellular forms that lack mitochondria). The enigmatic microsporidia seem to be derived from an endoparasitic chytrid ancestor similar to Rozella allomycis, on the earliest diverging branch of the fungal phylogenetic tree.

The Pezizomycetes (order Pezizales) is an early diverging lineage within the Pezizomycotina. A shared derived character, the operculate ascus, supports the Pezizales as monophyletic, although functional opercula have been lost in certain taxa. Phylogenetic relationships within Pezizales were studied using parsimony and Bayesian analyses of partial SSU and LSU rDNA sequences from 100 taxa representing 82 genera and 13 of the 15 families currently recognized. Three primary lineages are identified that more or less correspond to the A, B and C lineages resolved in previous analyses using SSU rDNA: (A) Ascobolaceae and Pezizaceae; (B) Discinaceae-Morchellaceae and Helvellaceae-Tuberaceae; (C) Ascodesmidaceae, Glaziellaceae, Pyronemataceae, Sarcoscyphaceae and Sarcosomataceae. In contrast the monotypic Rhizinaceae and Caloscyphaceae are resolved as two independent lineages. Bayesian analyses support a relationship among Rhizina and two species of Psilopezia (Pyronemataceae). Only lineage C is highly supported. The B and C lineages form a strongly supported monophyletic group. None of these lineages corresponds to earlier proposed suborders. The A and B lineages are supported by certain morphological features (e.g. ascus bluing reaction in iodine, cytology of spores and paraphyses, septal pore structures and excipulum structure); these characters have been Subject to homoplasy. Lineage C is the largest and most heterogeneous, and no unifying morphological features support its recognition. The Pyronemataceae, in which almost half of the species in the order are found, is not monophyletic because the Ascodesmidaceae and Glaziellaceae are nested within it. The relationships among all families in the C lineage remain uncertain. The origin of various forms of ascomata, including hypogeous forms (truffles and truffle-like), epigeous cleistothecia, simple reduced apothecia and highly elaborate, stipitate forms (helvelloid and morchelloid), are discussed.

To provide a robust phylogeny of Pezizaceae, partial sequences from two nuclear protein-coding genes, RPB2 (encoding the second largest subunit of RNA polymerase II) and β-tubulin, were obtained from 69 and 72 specimens, respectively, to analyze with nuclear ribosomal large subunit RNA gene sequences (LSU). The three-gene data set includes 32 species of Peziza, and 27 species from nine additional epigeous and six hypogeous (truffle) pezizaceous genera. Analyses of the combined LSU, RPB2, and β-tubulin data set using parsimony, maximum likelihood, and Bayesian approaches identify 14 fine-scale lineages within Pezizaceae. Species of Peziza occur in eight of the lineages, spread among other genera of the family, confirming the non-monophyly of the genus. Although parsimony analyses of the three-gene data set produced a nearly completely resolved strict consensus tree, with increased confidence, relationships between the lineages are still resolved with mostly weak bootstrap support. Bayesian analyses of the three-gene data, however, show support for several more inclusive clades, mostly congruent with Bayesian analyses of RPB2. No strongly supported incongruence was found among phylogenies derived from the separate LSU, RPB2, and β-tubulin data sets. The RPB2 region appeared to be the most informative single gene region based on resolution and clade support, and accounts for the greatest number of potentially parsimony informative characters within the combined data set, followed by the LSU and the β-tubulin region. The results indicate that third codon positions in β-tubulin are saturated, especially for sites that provide information about the deeper relationships. Nevertheless, almost all phylogenetic signal in β-tubulin is due to third positions changes, with almost no signal in first and second codons, and contribute phylogenetic information at the "fine-scale" level within the Pezizaceae. The Pezizaceae is supported as monophyletic in analyses of the three-gene data set, but its sister-group relationships is not resolved with support. The results advocate the use of RPB2 as a marker for ascomycete phylogenetics at the inter-generic level, whereas the β-tubulin gene appears less useful. {\textcopyright} 2005 Elsevier Inc.

Parsimony, maximum-likelihood and Bayesian analyses of SSU rDNA sequences of representative Laxa of Pezizomycetes, Eurotiomycetes, Dothideomycetes. Leotiomycetes and Sordariomycetes, all strongly support the cleistothecial fungi Orbicula parietina and Lasiobolidium. orbiculoides to be of pezizalean origin. Previous hypotheses of close affinities with cleistothecial Or highly reduced fungi now placed in the Thelebolales, Eurotiales or Onygenales are rejected. Orbicula parietina and L. orbiculoides are deeply nested within Pyronemataceae (which subsumes the families Ascodesmidaceae, Glaziellaceae and Otideaceac). LSU rDNA sequences suggest that Orbicula is nested within the apothecia-forming genus Pseudombrophila (including Nannfeldtiella and Fimaria) and that L. orbiculoides is closely related. Ascodesmis and Lasiobolus, which have been suggested as closely related to Orbicula and Lasiobolidium, are identified as a sister lineage to the Pseudombrophila lineage. Cleistothecial forms that have lost the ascus operculum and ability to discharge spores actively have evolved at least once in the Pseudombrophila lineage. Some species of Pseudombrophila produce subglobular ascomata initials that are closed early in development and open only in the mid-mesohymenial phase. We hypothesize that, in the Pseudombrophila, lineage, ascomata forms that never open are derived from ascomata that open late in development. The placement of O. parietina and L. orbiculoides within Pseudombrophila is supported by morphological characters, ecology and temperature optima for fruiting.

Based on an overview of progress in molecular systematics of the true fungi (Fungi/Eumycota) since 1990, little overlap was found among single-locus data matrices, which explains why no large-scale multilocus phylogenetic analysis had been undertaken to reveal deep relationships among fungi. As part of the project {\textquoteleft}{\textquoteleft}Assembling the Fungal Tree of Life{\textquoteright}{\textquoteright} (AFTOL), results of four Bayesian analyses are reported with complementary bootstrap assessment of phylogenetic confidence based on (1) a combined two-locus data set (nucSSU and nucLSU rDNA) with 558 species representing all traditionally recognized fungal phyla (Ascomycota, Basidiomycota, Chytridiomycota, Zygomycota) and the Glomeromycota, (2) a combined three-locus data set (nucSSU, nucLSU, and mitSSU rDNA) with 236 species, (3) a combined three-locus data set (nucSSU, nucLSU rDNA, and\ RPB2) with 157 species, and (4) a combined four-locus data set (nucSSU, nucLSU, mitSSU rDNA, and\ RPB2) with 103 species. Because of the lack of complementarity among single-locus data sets, the last three analyses included only members of the Ascomycota and Basidiomycota. The four-locus analysis resolved multiple deep relationships within the Ascomycota and Basidiomycota that were not revealed previously or that received only weak support in previous studies. The impact of this newly discovered phylogenetic structure on supraordinal classifications is dis- cussed. Based on these results and reanalysis of subcellular data, current knowledge of the evolution of septal features of fungal hyphae is synthesized, and a preliminary reassessment of ascomal evolution is presented. Based on previously unpublished data and sequences from GenBank, this study provides a phylogenetic synthesis for the Fungi and a framework for future phylogenetic studies on fungi.

A study of Chorioactis geaster (Sarcosomataceae) has shown the presence of several unreported or unconfirmed characters for this unusual and rare operculate discomycete. The ascospores are ornamented, they mature more or less simultaneously in all asci of a single ascoma, and asci have a thin hyphal base. The species is compared with species of the genera Cookeina and Microstoma (Sarcoscyphaceae) that also have this character. SEM shows open asci have a two-layered opercular region confirming TEM reports of differentiated wall layering in this region of the ascus. These features are discussed and the isolated systematic position of Chorioactis suggested by previous studies is confirmed.

An expedition to the Dominican Republic to survey discomycetes was conducted in January 2002. In this expedition, 111 discomycete samples were collected: 22 Pezizales, 81 Helotiales, 6 Ostropales and 2 Rhytismatales. This field trip added 39 new reports for the Dominican Republic. To date, 79 species of discomycetes are known in the Dominican Republic in the following orders: 34 Pezizales, 42 Helotiales, 2 Ostropales and 1 Rhytismatales. The great majority (87\%) of these species are our new reports for the Dominican Republic and about 38\% are new for the Greater Antilles and the Caribbean region. Most of the species of discomycetes known in the Dominican Republic are of tropical origin. Some of the reports are discomycete species from north temperate regions: Morchella, Gyromitra, Helvella, Pseudoplectania nigrella, Plectania melastoma, Leotia viscose, Podophacidium xanthomelum and Lachnum virgineum. Based on our work from Dominican Republic, we can conservatively predict 20\% of the material collected should represent new records and new taxa.

Species delimitation within the core group of Peziza is highly controversial. The group, typified by P. vesiculosa, is morphologically coherent and in previous analyses of LSU rDNA sequences it formed a highly supported clade. Phylogenetic diversity and species limits were investigated within the group using sequences from the complete ITS region (ITSI-5.8S-ITS2). Eighty-three specimens were selected for molecular study from a larger sample of material studied morphologically to explore the intra- and interspecific variation of each putative species. The sister group taxon, P. ampelina was used as the outgroup and two specimens of P. subcitrina were additionally included. Seven independent lineages of rDNA were identified (I-VII), each representing one to several species. These lineages form two larger clades, A (II, and I or III) and B (IV-VII), supported by macromorphology: small (generally \< 2 cm), shallowly cup- to disc-shaped apothecia (A) and large (up to 15 cm), deeply cup-shaped to expanded apothecia (B). The overall exciple structure (a stratified or non-stratified medullary layer) and to some degree spore surface relief, likewise support the groupings. Clade A contains taxa with smooth or nearly smooth spores (except for P. lohjaensis), while clade B contains taxa with a range of spore ornamentations, from smooth, finely warty to distinctly warty, and spiny. The position of groups I (P. vesiculosa and P. ammophila) and III (P. lohjaensis) are uncertain, and these taxa also deviate morphologically from the other clade A members. The following species are recognized based on morphology and ITS rDNA analyses: P. ammophila and P. vesiculosa (I); P. alcis, P. ampliata, P. domiciliana, P. fimeti, P. nivalis, and a number of putative species or intraspecific entities (II); P. lohjaensis (III); P. sp. c (IV); P. arvernensis (V); P. echinispora and P. sp. d (VI); and P. varia (VII). The nomenclature of these species is analyzed and taxa are typified as necessary. Based on ITS and morphology, we found no justification for recognizing more than one species in the {\textquoteright}P. varia complex{\textquoteright}, including 27 specimens that have been referred to under the names P. cerea, P. micropus and P. repanda, from an array of substrates and different geographical areas. Morphological characters previously used to delimit species within this complex, such as colour variation of the apothecia, presence or absence of a stipe, stratified or non-stratified medullary exciple (or thickness of the excipular layers), cell types in the outermost exciple and moniliform vs filiform paraphyses were not correlated with the subgroups supported by ITS analyses and appeared to be plastic. Therefore, P. cerea and P. micropus are placed in synonymy with P. varia. The name P. repanda is rejected. Levels of sequence divergence were low within group II, comprising 33 small apothecial specimens. Twelve fine-scale lineages were identified, but the analyses did not resolve relationships among these. P. granulosa sensu Boudier is considered a synonym of P. fimeti. These have previously been distinguished mainly by occurrence on various soil types, including burnt soil and soil mixed with sawdust or woodchips vs on dung. The substrate and habitat have been much emphasized in the taxonomy of Peziza, but the results obtained here indicate that populations on a diverse array of substrates may be closely related, or indeed, conspecific.

Cookeina, with seven recognized species, is one of the commonly encountered genera of the Sarcoscyphaceae (Pezizales) in tropical and subtropical areas around the world. Morphologically the species are distinguished by combinations of several features including ascospore shape and surface relief, presence and origin of apothecial hairs and presence or absence of gelatinous material within the cortical layer of the excipular tissue. Color of the hymenium, attributed to carotenoid pigments, is particularly variable in some collections especially those referred to as C. speciosa. In this study phylogenetic analyses were carried out using rDNA ITS and rDNA LSU sequences. Forty-four collections were studied which included a broad sampling of color variants of C. speciosa from a field site in Venezuela. The genus was shown to be monophyletic with several well-supported lineages. These analyses generally support the established, morphologically distinguished taxa within a monophyletic genus Cookeina. Collections referred to as C. speciosa segregate within a clade in which hymenial color differences are associated with groups within the clade. Cookeina sinensis is sister to C. tricholoma but is distinct from it; C. indica fails to resolve with any of the major clades. The placement of C. insititia is ambiguous but it falls within Cookeina and thus is considered in the genus Cookeina rather than in a separate genus, Boedijnopeziza.

A fungus collected in western Sichuan, China in 1997 is recognized as a new species of Pezicula based on morphological characters. The species is named Pezicula magnispora due to its large ascospores and comparatively small apothecia. Ascospores are brown and septate to muriform when discharged, but remain hyaline within the asci. The fungus grows oil the stem of a dead herbaceous plant. The distinctively large spores and type of substrate establish this as a new species.

Phylogenetic relationships among members of the Pezizaceae were studied using 90 partial LSU rDNA sequences from 51 species of Peziza and 20 species from 8 additional epigeous genera of the Pezizaceae, viz. Boudiera, Iodophanus, Iodowynnea, Kimbropezia, Pachyella, Plicaria, Sarcosphaera and Scabropezia, and 5 hypogeous genera, viz. Amylascus, Cazia, Hydnotryopsis, Ruhlandiella and Tirmania. To test the monophyly of the Pezizaceae and the relationships to the genera Marcelleina and Pfistera (Pyronemataceae), 6 species from the families Ascobolaceae, Morchellaceae and Pyronemataceae were included. Maximum parsimony and maximum likelihood analyses of these sequences suggest that the Pezizaceae is paraphyletic, because the non-amyloid Marcelleina is nested within it. If Marcelleina were transferred to the Pezizaceae, then the family would be monophyletic. Although the Pezizaceae is traditionally characterized by amyloid asci, our results indicate that the amyloid reaction is a symplesiomorphy, which has been lost in some lineages, e.g., in those including Marcelleina and Cazia. Nodes deep in the tree could not be resolved, but 7 groups of species (I-VII) are generally well supported or present in all trees. Peziza species, which constitute the core of the family, are present in all groups except group III, confirming the non-monophyly of the genus. The analyses suggest that the other included genera of the Pezizaceae are all nested within Peziza, the placement of Iodophanus being unresolved. The morphologically distinct Peziza gerardii, which forms a clade with Marcelleina, appears to be the sister group to the rest of the Pezizaceae. Morphological features were studied and evaluated in the context of the phylogeny. Distinct types of ascus amyloid reactions were found to support different rDNA lineages, e.g., a distinct amyloid ring zone at the apex is a synapomorphy for group IV, an intense and unrestricted amyloid reaction of the apex is mostly found in group VI, and asci that are weakly or diffusely amyloid in the entire length are present in group II. Other morphological features, such as spore surface relief, guttulation, excipulum structure and pigments, while not free from homoplasy, do support the groupings. Anamorphs likewise provide clues to higher-order relationships within the Pezizaceae. Several macro- and micromorphological features, however, appear to have evolved several times independently, including ascomatal form and habit (epigeous, semihypogeous or hypogeous), spore discharge mechanisms, and spore shape. Parsimony-based optimization of character states on our phylogenetic trees suggested that transitions to truffle and truffle-like forms evolved at least three times within the Pezizaceae (in group III, V and VI). The 9 hypogeous species included are nested in lineages with epigeous pezizaceous taxa. Species with apothecia of various shapes and with forcible spore discharge are spread among all groups and the apothecium is suggested to be symplesiomorphic in the Pezizaceae. The results indicate that the apothecia forming Pezizaceae have given rise to at least 3 different forms of hypogeous ascomata without forcible spore discharge: ptychothecia, stereothecia and exothecia.

A new genus Wenyingia (Otideaceae, Pezizales), based on Wenyingia sichuanensis, a new species, is reported from western Sichuan, China. An unusual membrane covering the hymenium, the structure and origin of which are discussed in this paper, distinguishes this genus from others in the family. The structure of the excipulum, size, shape and ornamentation of spores and pigmentation of the apothecia place this genus close to Tarzetta.

The internal transcribed spacers (ITS) of the nuclear ribosomal DNA have been sequenced from 29 collections of Phillipsia, mainly from the New World. The P domingensis complex, collections with a range of colors but otherwise referable to P domingensis s.l. based on spore ornamentation, were studied. Three distinctive species of Phillipsia also were included. The sequences were analysed to infer phylogenetic relationships within Phillipnsia, using parsimony. Morphological features were studied separately, and then evaluated in the context of the ITS phylogeny. Four distinct rDNA lineages, supported by ascospore ornamentation, were identified: the P. crispata the P. domingensis, the P. olivacea and the P. carnicolor lineages. SEM photographs of the ascospores are presented. Phillipsia lutea and another yellow form were nested within the P. dominagensis complex, of those with reddish hymenial colors. Color has been emphasized in taxonomy of Phillipsia, but these results suggest that individuals with strikingly different coloration may be closely related. Levels of ITS sequence divergence in the P. domingensis lineage were low. Based on these data, and morphology as studied thus far; there is no justification for recognizing segregate species within the P. domingensis complex. The Old World collections of the P. domingensis complex were nested within the New World collections, which implies that the P. domingensis lineage is geographically widespread. Phillipsia rugospora is plated in synonymy with P. olivacea and a detailed description of this taxon is given. A lectotype is designated for P. olivacea.

The order Pezizales has been divided into two suborders. One suborder, the Sarcoscyphineae, was originally described to include members whose asci were characterized by an unusual apical structure, the suboperculum. Disagreements as to how this structure should be defined, and indeed, whether or not it exists at all, have rendered the status of the suborder controversial. The two families within this suborder are the Sarcoscyphaceae and the Sarcosomataceae. Recent ultrastructural work demonstrates that there is an apical thickening which is restricted to the Sarcoscyphaceae. In order to test the monophyly of the suborders of the Pezizales and examine the relationships within the Sarcoscyphineae, phylogenetic analyses were carried out using DNA sequence data from the 18S rRNA gene. The strict consensus tree based upon these data shows both the Sarcoscyphineae and the Pezizineae as paraphyletic. These data suggest that the subordinal taxa currently recognized within the Pezizales should be abandoned and the taxonomy revised to reflect phylogenetic relationships. Strongly supported clades (i.e., greater than 95\% bootstrap value, 1500 replicates) include: the Pezizaceae, the Morchellaceae, the Sarcoscyphaceae, the Helvellaceae, and a clade that includes the Sarcosomataceae (which is paraphyletic), and the Otidiaceae (represented only by 2 taxa). The genus Pindara, formerly placed in the Sarcoscyphaceae, is nested within the Helvellaceae, and Wynnea, assigned to the Sarcosomataceae by some authors, is positioned in the Sarcoscyphaceae.

The literature on teleomorph-anamorph connections in the Orbiliaceae and the position of the family in the Leotiales is reviewed. 18S data show that the Orbiliaceae occupies an isolated position in relationship to the other members of the Leotiales which have so far been studied. The following form genera have been studied in cultures derived from ascospores of Orbiliaceae: Anguillospora, Arthrobotrys, Dactylella, Dicranidion, Helicoon, Monacrosporium, Trinacrium and conidial types that are referred to as being Idriella-like. Characteristics of the anamorphs are discussed and illustrated. Analyses of the ITS region of several of the isolates indicate that there are several well-supported clades within the Orbiliaceae. These clades can be recognized based on the anamorphs produced. They are: an Arthrobotrys-Monacrosporium clade, a Dicranidion clade, and a Helicoon clade. Outside of these clades is a well-supported clade which contains two Arthrobotrys isolates which were derived from conidia produced on natural substrates. The taxonomic and phylogenetic implications of this information are discussed. The Orbiliaceae occur in nature on substrates that are either continually wet or on substrates that periodically dry out. Field observations indicate that those taxa which occur on wet substrates produce perennial mycelia. Some discussion is provided on the way in which scientific information is viewed and can be used.

Cultures derived from ascospores of two collections both referable to Orbilia auricolor produced anamorphs which were assigned to Arthrobotrys cladodes var. macroides and A. oligospora var. oligospora. These morphologically distinct isolates formed nematode-capturing hyphal networks when nematodes were present. Descriptions of the Arthrobotrys isolates are given. At least one other nematophagous hyphomycete is connected with a teleomorph that can be referred to O. auricolor suggesting that O. auricolor is not a single entity but a species complex.

Cultures derived from a collection of Orbilia fimicola produced an Arthrobotrys anamorph. This anamorph was identified as A. superba. A discomycete agreeing closely with O. fimicola was previously reported to be associated with a culture of A. superba but no definitive connection was made. In the present study, traps were formed in the Arthrobotrys cultures when nematodes were added. The hypothesis is put forth that other Orbilia species might be predators of nematodes or invertebrates based on their ascospore and conidial form.

Byssonectria, previously placed in the Hypocreales, is treated as a member of the Pezizales; Pseudocollema and Inermisia are considered synonyms. Four species are recognized from North America: B. terrestris, a new combination which provides the oldest traceable name for the common North American and European species; B. cartilagineum, also a new combination, is based on the type species of Pseudocollema; B. fusispora; and B. seaveri, a new species for a large-spored North American collection. The ascomata of Byssonectria cartilagineum and B. terrestris are initially cleistohymenial. They open during the mesohymenial phase. The ascogonium is a multicellular filament, one cell of which produces ascogenous hyphae. This filament becomes surrounded by vegetative hyphae which build up the body of the ascoma. Young cleistohymenial ascomata could be mistaken for perithecia; such a mistake seems to account for original placement of the type species of Byssonectria in the Hypocreales.
