拟金钱菌属的4个中国新记录种

Four new record species of Collybiopsis in China

【目的】对采集于江西省官山国家级自然保护区的9份拟金钱菌属Collybiopsis标本进行物种鉴定。【方法】依据宏观形态和显微结构比较,结合ITS和LSU基因序列系统发育进行分析与鉴定。【结果】9份拟金钱菌属标本分属于7个种,即韩国拟金钱菌(Collybiopsis. Koreana)、富尔瓦拟金钱菌(C. fulva)、梅尼胡内拟金钱菌(C.menehune)、东方缺裸拟金钱菌(C. orientisubnuda)、安杜拉塔拟金钱菌(C. undulata)、茂盛拟金钱菌(C. luxurians)和多纹拟金钱菌(C. polygramma)。【结论】参考中国截至目前已报道的拟金钱菌属物种,确定韩国拟金钱菌、富尔瓦拟金钱菌、梅尼胡内拟金钱菌和东方缺裸拟金钱菌为我国新记录种,其余3种为江西省新记录种。

[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.
