@article {1332105, title = {New species of Pseudosperma (Agaricales, Inocybaceae) from Pakistan revealed by morphology and multi-locus phylogenetic reconstruction}, journal = {MycoKeys}, year = {2020}, pages = {1-31}, abstract = {During fungal surveys between 2012 and 2014 in pine-dominated forests of the western Himalayas in Pakistan, several collections of\ Pseudosperma\ (Agaricales,\ Inocybaceae) were made. These were documented, based on morphological and molecular data. During this work, three new species came to light, which are here formally described as\ Pseudosperma\ brunneoumbonatum,\ P.\ pinophilum\ and\ P.\ triacicularis. These species belong in the genus\ Pseudosperma\ fide\ Matheny et al (2019)\ =\ Pseudosperma\ clade\ fide\ Matheny (2005)\ =\ Inocybe\ sect.\ Rimosae\ s.s.\ fide\ Larsson et al. (2009). Macro- and micro-morphological descriptions, illustrations and molecular phylogenetic reconstructions of the studied taxa are provided. The new species are differentiated from their close relatives by basidiospore size and colouration of basidiomata. Molecular phylogenetic relationships are inferred using\ ITS\ (ITS1{\textendash}5.8S{\textendash}ITS2),\ nrLSU\ and\ mtSSU\ sequence data. All three newly-described taxa likely share an ectomycorrhizal association with trees in the genus\ Pinus. In addition, five names are recombined in\ Inosperma,\ Mallocybe\ and\ Pseudosperma. These are\ Inosperma\ vinaceobrunneum,\ Mallocybe\ erratum,\ Pseudosperma\ alboflavellum,\ Pseudosperma\ friabile\ and\ Pseudosperma\ neglectum.}, url = {https://doi.org/10.3897/mycokeys.69.33563}, author = {Saba, Malka and Haelewaters, Danny and Pfister, Donald and Khalid, Abdul Nasir} }
