摘要从云南、贵州两省兰科8属植物上分离到8种炭疽菌22个菌株。14个菌株来自病斑并且是病原体，4个来自掉落/死亡的花或茎，4个作为内生菌分离。通过形态学研究和多位点系统发育分析（ACT、Tub 2、CAL、CHS I、GPDH和ITS）对菌株进行表征。根据形态特征和多位点序列数据，对兰花炭疽菌（Colletotrichum orchidearum）和新种卡氏炭疽菌（Colletotrichum karstii）进行了描述和图解。收集的其他Colletotrichum物种的报告与说明。
Abstract Twenty-two strains of Colletotrichum, representing eight species, were isolated from eight genera of Orchidaceae in Yunnan and Guizhou provinces in China. Fourteen strains were from lesions and are pathogens, four were from fallen/dead flowers or stems and four were isolated as endophytes. The strains are characterized through morphological studies and multilocus phylogenetic analysis (ACT, Tub 2, CAL, CHS I, GPDH and ITS). Colletotrichum orchidearum and the new species Colletotrichum karstii are described and illustrated, based on morphological characters and multilocus sequence data. Collections of the other Colletotrichum species are reported with notes.
