Abstract

This paper sorts out the taxonomy of species affiliated withPulveroboletusraveneliiin the Guineo-soudanian and Zambezian woodlands of Africa. Morphological and genetic characters of AfricanPulveroboletuscollections were studied and compared to those of North American and Asian species. A phylogenetic analysis showed that the African specimens form a subclade, sister to the Asian and American taxa. Although clamp connections have previously never been reported fromPulveroboletus, all specimens of the African subclade show very small clamp connections. Two new African species,Pulveroboletusafricanussp. nov.andP.sokponianussp. nov., are described and illustrated. Comments concerning morphology and identification, as well as distribution and ecology, are given for both species.
