Studies in Perenniporia s.l. (Polyporaceae): African taxa VII. Truncospora oboensis sp. nov., an undescribed species from high elevation cloud forest of São Tome

In the frame of an ongoing survey of the genus Perenniporia sensu Ryvarden & Johansen (1980) (Basidiomycota) in sub-Saharan Africa, the status of some collections from high elevation, cloud forest of Obô National Park, São Tomé, and their relation to Perenniporia sensu stricto and Truncospora have been analyzed. The genus Truncospora is redefined and a new species, Truncospora oboensis is proposed. The new combination Truncospora detrita is also proposed. In sub-Saharan Africa, Truncospora is now represented by two species: Truncospora ochroleuca sensu Ryvarden & Johansen (1980) occurring mainly in open woodlands and Truncospora oboensis, known from high altitude cloud forest of São Tomé.
