Zusammenfassung:Brasilioporus olivaceoflavidus, gen. et sp. nov., Brasilioporus simoniarum, sp. nov., Neotropicomus australis, gen. et sp. nov., and Nevesoporus nigrostipitatus, gen. et sp. nov. (Boletaceae, Boletales, Basidiomycota), are described from the endangered Atlantic Forest biome of eastern Brazil. New combinations into these new genera are proposed for the Guyanese taxa Xerocomus parvogracilis, Tylopilus rufonigricans, and Tylopilus exiguus. Boletaceae subfamily Chalciporoideae was recircumscribed to include the new genus Nevesoporus. Molecular phylogenetic analyses using a multilocus data set (ITS+28S+TEF1+RPB1+RPB2) from a large taxon set across the Boletaceae justify recognition of the new genera. Morphological, ecological, and DNA sequence data are provided for the new species. A key to known native and introduced bolete species from the Brazilian Atlantic Forest is provided.
