Four new resupinate species, Perenniporia hainaniana, P. macropora, P. russeimarginataand P. subtephropora, are described as new from southern China on the basis of morphological and molecular examination. Perenniporia hainanianais characterized by a perennial growth habit, cream to buff pore surface, a dimitic to trimitic hyphal system with amyloid skeletal hyphae and presence of dendrohyphidia. Perenniporia macroporais distinguished by an annual growth habit, large pores (2–3 per mm), a dimitic hyphal system with branched skeletal hyphae and presence of dendrohyphidia. Perenniporia russeimarginatadiffers from other species in the genus by a perennial growth habit, white to cream pore surface and reddish to reddish brown sterile margin. Perenniporia subtephroporais characterized by a perennial growth habit, cream-buff to grayish buff pore surface, hymenophoral trama becoming black in KOH and a dimitic hyphal system with branched skeletal hyphae. Phylogenetic analysis inferred from the ITS and LSU-rDNA regions revealed eight clades for Perenniporiasensu lato with the four new species recognized in Perenniporiasensu stricto. The Perenniporia ochroleucagroup, P. vicinagroup, P. martiagroup, P. subacida, Microporellus, Perenniporiellaand Abundisporus, formed monophyletic entities respectively, and they are not related to P. medulla-panis(generic type), which belongs to Perenniporiasensu stricto. Abundisporus, Microporellusand Perenniporiellawere widely applied as generic names. Other generic or clade names, Hornodermoporus, Truncospora, Vanderbyliaand the P. subacidaclade, have not been widely applied, but they are valid higher level taxa containing former species of Perenniporia. A key to genera and clades allied with Perennioporiasensu stricto and a key to species of Perennioporiaare provided.
