Abstract

We describe four new nodulose-spored species of Inocybe from tropical regions of Africa: I. beninensis, I. flavipes, I. fuscobrunnea and I. pallidiangulata. The new species are recognised based on morphological data and phylogenetic analyses of ITS, 28S and RPB2 sequences. Phylogenetic analyses indicated that I. flavipes and I. beninensis are part of a subclade leading to the I. calida group. Inocybe fuscobrunnea appears sister to the I. asterospora group. Inocybe pallidiangulata is nested within a clade of mainly tropical species from South Asia, Africa, and South America, close to the subclade of I. lilacinosquamosa and I. ayangannae from Guyana. Complete descriptions and illustrations, including photographs and line drawings, and a key to nodulose-spored taxa of tropical African species of Inocybe are provided.
