ABSTRACT=<p><italic>Phaeolus schweinitzii</italic> (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 <italic>P. schweinitzii</italic> is a species complex, including six taxa. <italic>P. schweinitzii</italic> sensu stricto has a distribution in Eurasia; the samples from Northeast and Southwest China are distantly related to <italic>P. schweinitzii</italic> sensu stricto, and two new species are described after morphological, phylogenetic, and geographical analyses. The species growing on <italic>Larix, Picea</italic>, and <italic>Pinus</italic> in Northeast China is described as <italic>Phaeolus asiae-orientalis</italic>. Another species mostly occurring on <italic>Pinus yunnanensis</italic> in Southwest China is <italic>Phaeolus yunnanensis</italic>. In addition, three taxa distributed in North America differ from <italic>P. schweinitzii</italic> sensu stricto. <italic>Phaeolus tabulaeformis</italic> (Berk.) Pat. is in Southeast North America, “<italic>P. schweinitzii</italic>-1” in Northeast North America, and “<italic>P. schweinitzii</italic>-2” in western North America.</p>
