A new poroid wood-inhabiting fungal genus, Flammeopellis, is proposed based on morphological characters and molecular evidence. The genus is typified by Flammeopellis bambusicola sp. nov., which macroscopically is characterized by an annual growth habit and stipitate basidiocarps with a reddish-brown pileal cuticle. Microscopically, it has a dimitic hyphal system with generative hyphae frequently with simple septa, occasionally with clamp connections, strongly dextrinoid and cyanophilous skeletal hyphae, and ellipsoid to drop-shaped, pale yellowish, thick-walled, smooth, weakly dextrinoid and cyanophilous basidiospores. Phylogenetic analysis based on molecular data of ITS+LSU nrRNA gene regions indicates that Flammeopellis belongs to the core polyporoid clade and is closely related to Perenniporiella. Combined ITS+nLSU+mtSSU+TEF1 sequence data of representative taxa in Perenniporia sensu lato demonstrated that Flammeopellis bambusicola grouped with the Perenniporiella clade, but formed a monophyletic lineage with a strong support (100 % BP, 1.00 BPP). The morphological and molecular evidence confirmed the placement of the new genus in the core polyporoid clade and established its relationships with similar genera.
