 The genus Phylloporus is a gilled bolete and a typical ectomycorrhizal mushroom which froms mycorrhizal with woody Fagaceae or Pinaceae. Collections of Phylloporus were made from Xiaozhongdian (Shangri-La), Haitang (Baoshan) and Menssong (Xishuangbanna) from May to October 2012. Morphology and sequence analysis revealed that the Phylloporus collections belonged to seven groups and five species: P. imbricatus (Xiaozhongdian, Shangri-La), P. pachcystidiatus and P. yunnanensis (Haitang, Baoshan), P. rubiginosus (Mengsong, Xishuangbanna) and P. megacystidiatus sp. Nov. (Mengsong, Xishuangbanna). In this paper we introduce one new Phylloporus species: Phylloporus megacystidiatus sp. Nov., and new record P. rubiginosus for the first time in Yunnan Province, China. The new species and the new record are described and illustrated with drawings and color photos. Also the species and new record are compared with similar taxa.
