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


ABSTRACT: Here, we describe three new species of Inosperma from Tropical Africa: Inosperma africanum, I. bulbomarginatum 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 clade 1 with weak support, I. bulbomarginatum is sister of Old World Tropical clade 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.
