MycoKeys 77: 97–116. https://doi.org/10.3897/mycokeys.77.60084 Abstract Here, we describe three new species of Inosperma from Tropical Africa: Inosperma africanum, I. bulbomar- ginatum 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.
