Three new species of Inosperma (Agaricales, Inocybaceae) from Tropical Africa

Here, we describe three new species of Inosperma from Tropical Africa: Inosperma africanum, I. bulhomarginatum and I. flavobrunneum. Morphological and molecular data show that these species have not been described before, hence need to be described as new. The phylogenetic placements of these species were inferred, based on molecular evidence from sequences of 28S and RPB2. Additional analysis using ITS dataset shows interspecific variation between each species. Phylogenetic analyses resolve I. flavobrunneum in Old World Tropical lade I with weak support, I. bulbomarginatum is sister of Old World Tropical clack 1 and I. africanum is indicated as sister to the rest of Inosperma. Complete description and illustrations, including photographs and line drawings, are presented for each species. A new combination of Inocybe shawarensis into Inosperma is also proposed.

Automated summary

Three new species of Inosperma from Tropical Africa were described, with morphological and molecular data confirming their novelty. Phylogenetic placements of these species were inferred based on molecular evidence, alongside interspecific variation analysis using ITS dataset. Complete descriptions, illustrations, and a new combination proposal were provided for each species.
