Rommelaarsia flavovirens gen. et sp. nov. (Helotiales), a new discomycete on Equisetum with a peculiar asexual state.
Ascomycete.org , 7 (6) , pp. 321-330.
AbstractRommelaarsia avovirens gen. et sp. nov. is proposed. This inoperculate discomycete is known only from two collections in Western Europe, fruiting in spring on dead stems of Equisetum arvensis. An a - liation with the family Hyaloscyphaceae is suggested by the presence of short hairs on the super cially gro- wing apothecium. The species is associated with an unusual, likewise unknown asexual state with large multiguttulate, holoblastic phragmoconidia formed in sporodochia. Phylogenetic analyses of the internal transcribed spacer (ITS) and large subunit (LSU) ribosomal DNA show that Rommelaarsia has an uncertain position within the Helotiales. Our analyses consistently show a close relationship to Cistella and Psilachnum, but there is no support for this placement. Bayesian analysis moderately supports the Cistella + Psilachnum+ Rommelaarsia clade, which hints at the placement of Rommelaarsia within Hyaloscyphaceae. This agrees with the morphological data.

Cookeina korfii, a new species hidden in Cookeina tricholoma.
Ascomycete.org , 7 (6) , pp. 331-335.
AbstractCookeina kor i (Ascomycetes, Pezizales, Sarcoscyphaceae) is described from the Philippines. Ascospores are smooth, smaller than Cookeina tricholoma (Mont.) Kuntze, and hairs are more exuous than in C. tricholoma. Analyses of the ITS region shows it to be close to Cookeina tricholoma and Cookeina sinensisZ. Wang.

Pezizacea taxonomy and classification: Boudier, Cooke and Korf.
Ascomycete.org , 7 (6) , pp. 239-244.
AbstractRichard Korf is an important gure in the study of discomycetes. His contribution as teacher and scholar in relationship to Boudier’s masterwork, the Icones Mycologicae, is commented upon particularly in regard to the classi cations used for the Pezizaceae. Although it has been common practice to recognize a single genus Peziza for most of the species in the Pezizaceae, molecular phylogenetic studies have shown that the genus Peziza is diverse and is not monophyletic. Boudier’s classi cation shows a more accurate pic- ture of the diversity within the family than later classi cations. Comments on the Icones and Cooke’s Myco- graphia are included as they relate to graduate training and opportunities o ered by Richard Korf in his long career as a teacher.

Bringing Laboulbeniales into the 21st century: enhanced techniques for extraction and PCR amplification of DNA from minute ectoparasitic fungi.
IMA Fungus , 6 (2) , pp. 363–372.
AbstractLaboulbeniales is one of the most peculiar oders of Ascomycota. These fungi are characterized by an ectoparasitic life-style on arthropods, determinate growth, lack of an asexual stage, high species richness, and intractability to culture. The order Laboulbeniales, sister to Pyxidiophorales, has only recently been assigned a separate class, the Laboulbeniomycetes, based on very fewribosomal DNA sequences. So far, DNA isolations and PCR ampli cations have proven dif cult. Here,we provide details of isolation techniques and the application of commercially available kits that enableef cient and reliable genetic analyses of these fungi. We provide 43 newly generated Laboulbenialesribosomal DNA sequences, among which are the rst published sequences for species in the generaGloeandromyces, Herpomyces, Laboulbenia, Monoicomyces, and Polyandromyces. DNA extractions were possible using from 1 to 30 thalli from hosts preserved in ethanol (70–100 %). In two cases, we successfully isolated DNA from thalli on dried insect collections. Laboulbeniales molecular systematics could be substantially enhanced through these improved methods by allowing more complete sampling of both taxa and gene regions.

Laboulbeniales (Ascomycota) of the Boston Harbor Islands I: species parasitizing Coccinellidae and Staphylinidae.
Northeastern Naturalist , 22 (3) , pp. 459-477.
AbstractThis paper, based on a recent comprehensive sampling of insects, is the rstreport of Laboulbeniales from the New England region since the 1930s. We present 7 new records of laboulbenialean parasites on Staphylinidae (rove beetles) and Coccinellidae (lady beetles) from the Boston Harbor Islands National Recreation Area. These are Clonophoro- myces nipponicus Terada & I.I. Tav., Hesperomyces virescens Thaxt., Ilyomyces cf. maireiF. Picard, Laboulbenia philonthi Thaxt., Peyritschiella protea Thaxt., Stichomyces conoso- matis Thaxt., and Teratomyces actobii Thaxt. One of these parasite species, C. nipponicus, has not been found previously outside of its type locality in Japan. Examination of Roland Thaxter’s 1891–1932 slides led to the designation of lectotypes for L. philonthi, P. protea,S. conosomatis, and T. actobii. The following synonymy is established: Teratomyces brevi- caulis Thaxt. = T. actobii. In addition, we discovered new localities for H. virescens (from Canada, Cuba, Guatemala, and Japan) and L. philonthi (from Canada, Grenada, Panama, Trinidad, and Venezuela).
