Molecular and morphological data reveal two new polypores (Polyporales, Basidiomycota) with reddish brown to orange basidiomata from China.

Two taxonomically controversial polypore genera with reddish brown to orange basidiomata that stain reddish with KOH solution, and , are revised based on additional sampling, morphological examination, and phylogenetic analysis of a combined dataset of ITS1-5.8S-ITS2-nLSU sequences. is a monophyletic genus belonging to Phanerochaetaceae, whereas is a polyphyletic genus belonging to Meruliaceae. and s. str. are circumscribed, and two new species - and - are described and illustrated from temperate China. In addition, four new combinations, viz. , , and , are proposed based on morphology and phylogenetic analysis. The relationships between and are discussed.
