ABSTRACT: A morphological analysis of 35 species of Phellinus collected in southern Brazil resulted in the recognition of a group of nine species with a set of differentiating characters – presence of hymenial setae, incrusted generative hyphae, and hyaline, thin-walled, non-dextrinoid and acyanophilous basidiospores. These features define the genus Fuscoporia, and the nine species are accepted in this genus. Three new combinations are proposed.
