[Objective]This study was conducted to identify nine specimens of Collybiopsis genus collected from Guanshan National Nature Reserve in Jiangxi Province.[Method]The specimens were identified through macroscopic morphology and microstructure observations,along with phylogenetic analysis by using ITS and LSU.[Result]The results showed that there were seven distinct species,including C.koreana,C.fulva,C.menehune,C.orientisubnuda,C.undulata,C.luxurians and C.polygramma.[Conclusion]In review of Collybiopsis species reported hitherto,it was confirmed that four species were reported for the first time in China:C.koreana,C.fulva,C.menehune and C.orientisubnuda.Additionally,three species,namely C.undulata,C.luxurians and C.polygramma,were new records for Jiangxi Province.
