摘要
新定名的甘肃虫草Cordyceps gansuensi与冬虫夏草Cordyceps sinensi形态相似。 蛹虫草Cordyceps militaris具有拟青霉型（Paecilomyces-type）和轮枝孢型（Verticillium-type）两类无性型。此研究对5.8S rRNA基因 及ITS2间区DNA序列的分析结果表明，甘肃虫草和冬虫夏草的DNA序列相同，属于同一种；蛹虫草的两类无性型具有分子水平上的遗传趋异性。
Cordyceps gansuensis, C. sinensis and C. militaris are reexamined in this study.Cordyceps gansuensis morphologically resembles C.sinensis, while C.militaris has two different types of anamorphs, the Paecilomyces-type and the Verticillium-type. Analysis of DNA sequences of the 5.8S rRNA gene and partial internal transcribed spacer (ITS2) region of the fungi indicate that C.gansuensis and C.sinensis are conspecific and that the two types of anamorphs of C.militaris are diverse at molecular level.
