摘　　要：我国重要药用真菌蝉花的分类地位和学名在国内外长期混乱,因其有性型未被发现,长期以来误作为根据巴西标本命名的Isaria (Paecilomyces) cicadae。作者最近在井冈山发现了其有性型,研究了标本及分离物的形态特征及多位点系统发育特征,并与GenBank中相关种类的序列进行了对比,证明I.cicadae是物种复合群,确定蝉花是虫草科虫草属中的新种,使用传统药用真菌蝉花的古老名称将其命名为Cordycepschanhua。蝉花子座淡橙色到淡桔黄色,子囊壳半埋生,475–602×222–319μm,子囊孢子246–360×1.5–1.8μm,分孢子圆筒形,6.4–13.8×2.1–3.1μm。孢梗束淡黄色至淡黄褐色,分生孢子长椭圆形或圆筒形,3.5–10.5×1.5–4.5μm。The systematic position and scientific name of"chanhua",an important cordycipitoid mushroom has long been chaotic.Because its teleomorph was unknown,it has long been regarded as Isaria(Paecilomyces)cicadae named based on a Brazilian specimen.The teleomorph of this taxon was recently discovered from Mt.Jinggangshan,Eastern China.In the present paper,the teleomorph and anamorph of the species were studied morphologically and multigene-phylogenetically,the hypothesis that I.cicadae was a species complex was demonstrated,and"chanhua"was verified as a new species in the genus Cordyceps of Cordicipitaceae and then Cordyceps chanhua was proposed using the ancient Chinese name"chanhua"as its epithet.Stromata of C.chanhua are light orange to light saffron,ovoid,476–602×222–319μm;ascospores are filiform,246–360×1.5–1.8μm and part spores are 6.4–13.8×2.1–3.1μm.Conidia are long ellipsoid or cylindrical,3.5–10.5×1.5–4.5μm.
