Inonotus rwenzonanus (Basidiomycota, Hymenochaetales) is described as new from the Rwenzorei Mountain range, in the Democratic Republic of Congo The species is above all characterized by the combination of a thick, resupmate basidiomata, small pores, long extra-hymenial setae (setal hyphae) in the hymenophoral trama and the subiculum, abundant, variable shaped hymenial setae, and mostly ellipsoid, slightly thick-walled, very pale yellowish basidiospores. It is compared ot I pegleri, which is morphologically the closest species, also occurring in Africa. Its phylogenetic affinities are clearly within the Inontus clade sensu Fischer and Wagner, but the relationships within this clade are, for the time being, still poorly resolved.
