An endophytic strain (designated as strain SYPF 8335) was isolated from a root of Panax notoginseng in Wenshan district, Yunnan province of China. Strain SYPF 8335 grew very slowly and formed white colonies. Phylogenetic analysis of four loci indicated that strain SYPF 8335 was placed in the Drechmeria clade with Drechmeria campanulata as its closest phylogenetic neighbour. The nucleotide differences between strain SYPF 8335 and D. campanulata are 30 substitutions in the internal transcriber region region. A key morphological feature that differentiates the two fungi is that D. campanulata produces campanulate conidia. Combined with the morphology and molecular analyses, a new species named Drechmeria panacis sp. nov., is proposed.
从中国云南省文山地区三七的根部分离出一株内生菌株（命名为SYPF 8335菌株）。SYPF 8335菌株生长非常缓慢，形成白色菌落。对四个基因座的系统发育分析表明，SYPF 8335菌株与钟形腐霉同属腐霉分支，且与钟形腐霉的亲缘关系最近。SYPF 8335菌株与钟形腐霉之间的核苷酸差异在内转录间隔区有30个替换。区分这两种真菌的一个关键形态特征是钟形腐霉产生钟形分生孢子。结合形态学和分子分析，提出了一个新物种，命名为钟形人参腐霉（Drechmeria panacis sp. nov.）。
