Genus Inosperma (Kühner) Matheny & Esteve-Rav.

REMARKS

The traditional ectomycorrhizal genus Inocybe (Fr.) Fr. , with an estimated 1000 species worldwide, is still very little known on the African continent although it is not rare at all; Buyck and collaborators collected more than 25 years ago already more than 14 different species in the Zambian miombo woodlands of which only two had been officially published ( Buyck & Eyssartier 1999). The checklist of macrofungi for South Africa ( Kinge et al. 2020) only counts eleven Inocybe in this part of the continent, and more than half of them are named after European species that have little chance of being found in the remainder of Africa, unless under imported host trees. Pegler (1977) described five Inocybe from East Africa, and apart from a few articles describing one or two new tropical African species ( Watling 2001; Matheny & Watling 2004; Matheny et al. 2017), the exact African diversity of this group of fungi remains largely unexplored.

The old Friesian genus Inocybe was fairly polyphyletic ( Matheny et al. 2009) and has been recently divided into several genera: Inocybe , Nothocybe Matheny & K. P. D. Latha , Pseudosperma Matheny & Esteve-Rav. , Auritella Matheny & Bougher , Mallocybe (Kuyper) Matheny, Vizzini & Esteve-Rav. , Tubariomyces Esteve-Rav. & Matheny and Inosperma (Kühner) Matheny & Esteve-Rav. ( Matheny & Bougher 2006; Matheny et al. 2019).

With their fibrillose-rimose cap, smooth stipe and hymenium without any cystidia, the following three new species from the Zambezian miombo woodlands belong to the genus Inosperma ( Matheny et al. 2019) .
