Eleven taxa of s.s., , and in Polyporales are included in the phylogenetic analyses of nuc rDNA ITS1-5.8S-ITS2 (ITS), D1-D2 domains of nuc 28S rDNA (28S) and RNA polymerase II second-largest subunit () sequences. New species and are described and illustrated. , from south-eastern China, is closely related to , and , from northern China, is related to and . specimens from temperate to tropical areas with varied hymenophore configurations all cluster together in a fully supported clade. and are shown to be synonyms of , which is phylogenetically related to . Four new combinations, , , and , are proposed. Revised generic descriptions of and are provided with keys to the six accepted species in each genus. A list of all names in and are presented with their current taxonomic status. Type specimens of and were examined and determined to be later synonyms of and , respectively.
