摘　　要：分别从云南省剑川县和香格里拉县采集到鸡油菌属(Cantharellus)真菌的东亚/北美/大洋洲间断分布种红鸡油菌(C.cinnabarinus)和东亚/北美间断分布种太平洋金色鸡油菌(C.formosus)。对两者进行了形态学描述和基于核糖体大亚基(LSU nrDNA)的分子系统学分析。研究结果表明中国原被定为C.cinnabarinus的标本代表着一个尚未发表的新分类单元,而本文报道的红鸡油菌为真正的C.cinnabarinus;太平洋金色鸡油菌为中国新纪录种,以其暗褐色的子实体区别其近似种C.cibarius。研究标本保存于中国科学院昆明植物研究所隐花植物标本馆。Based on materials obtained from Jianchuan and Shangri-La,Yunnan,China,two species with intercontinental disjunct distribution pattern of the genus Cantharellus were reported here： Eastern Asia-Australasia-North America disjunct C.cinnabarinus and Eastern Asia-North America C.formosus.Morphological description and phylogenetic analysis based on LSU nrDNA were made.The results showed that Chinese specimens formerly labeled as C.cinnabarinus turn out to be a taxon to be described and the material presented here represents the true C.cinnabarinus.C.formosus is a new record to China.It is distinguished from its closely related C.cibarius by the much duller Basidiomata.Specimens studied are deposited in Herbarium of Cryptogams,Kunming Institute of Botany,Chinese Academy of Sciences（HKAS）.
