New species of Mallocybe (Agaricales, Inocybaceae) from Pakistan based on morphological and molecular evidence.

The Inocybaceae Jülich is a monophyletic family encompassing ectomycorrhizal fungi with worldwide distribution and is estimated to contain 1050 species. Mallocybe (Kuyper) Matheny, Vizzini & Esteve-Rav was first described as a subgenus of Inocybe (Fr.) Fr. but recently Matheny et al. elevated Mallocybe to one of seven genera in Inocybaceae. Within the family Inocybaceae, many species of Mallocybe have been reported, but there are only a few reports of this genus from Pakistan. In this study, six collections of Mallocybe were studied by morphological and phylogenetic methods. Phylogenetic analyses based on sequence data from two different loci (ITS and LSU) using maximum likelihood and maximum parsimony methods were performed to infer species relationships within Mallocybe. Results indicated that these six collections encompass two new species of Mallocybe i.e. M. pakistanica and M. pinicola, from Pakistan. Their detailed morphological descriptions and illustrations are also provided. In addition, comparison with morphologically closely related taxa is also discussed. A key to the described taxa of Mallocybe from Pakistan is also provided. This genus is poorly known in Pakistan, with only two species that were known before this study: M. leucoblema (Kühner) Matheny & EsteveRav. and M. velutina Saba & Khalid. With the contribution of this research work, the number of known taxa of this genus has been raised to sixty worldwide while four from Pakistan. However, a considerable number of taxa have yet to be formally described, and the number of the species will likely increase as more collections are studied from under-explored localities.
