Two new forest pathogens in (Polyporales, Basidiomycota) on Chinese coniferous trees were confirmed by molecular phylogeny.

(Fr.) Pat. was originally described in Europe and is considered a common forest pathogen on conifers in the Northern Hemisphere. Our molecular phylogeny based on samples from China, Europe, and North America confirms that is a species complex, including six taxa. sensu stricto has a distribution in Eurasia; the samples from Northeast and Southwest China are distantly related to sensu stricto, and two new species are described after morphological, phylogenetic, and geographical analyses. The species growing on , and in Northeast China is described as . Another species mostly occurring on in Southwest China is . In addition, three taxa distributed in North America differ from sensu stricto. (Berk.) Pat. is in Southeast North America, "-1" in Northeast North America, and "-2" in western North America.
