Abstract
During a survey of polypores in the montane forest of the Ôbo de São Tomé National Park, in the western African, equatorial island of São Tomé, a specimen that was, a priori, related to Fomitopsis showed deviating features including subglobose basidiospores with a large gutta. The gross morphology of the basidiome, the hyphal system, the subglobose basidiospores and a brown rot pointed toward Niveoporofomes. Phylogenetic inferences based on multiple loci dataset (ITS-LSU-SSU-TEF1-RPB2) confirmed the placement, and Niveoporofomes oboensis is described as new. The species is compared to Fomitopsis widdringtoniae, known from southeast Africa, which is characterized also by subglobose basidiospores; hence, the new combination N. widdringtoniae is proposed. The new combination Niveoporofomes globosporus (basionym Trametes globospora) is also proposed based on phylogenetic analyses. A key to the species of Fomitopsis, Niveoporofomes, Rhodofomes and Rhodofomitopsis in Tropical Africa is presented.
