CORDYCEPS SPP. AND SOME OTHER ENTOMOPATHOGENIC FUNGI FROM THE EMEI MOUNTAIN PRESERVE IN CHINA

采自四川省峨眉山自然保护区的虫草及其相关昆虫病原真菌，其中除有常见的蛹虫草Cordycepsmilitaris（Vuill．）Fr，粉被虫草（CordycepspruinosaPetch），蝉拟青霉Paecilomycescicadae（Miquel）Samson，球孢白僵菌Beauveriabassiana（Bals．）Vuill等昆虫病原真菌外，将主要描述峨眉虫草新种（CordycepsemeiensisA.Y.LiuetLiangsp.nov.），龙洞虫草新种（CordycepslongdongensisA.Y.LiuetLiangspnov．），暗绿虫草新记录种（CordycepsatrovirensKob．etShim．）和蛹虫草球头变种新记录种Cordycepsmilitarisvar.sphaerocephala（Schw）Fr．等几种虫草菌。

Eight species of entomogenous fungi were collected from the EmeiMountain Preserve in Sichuan Province. They are Cordeceps emeiensis sp. nov., C.Iogndongensis sp, nov., C. atrovirens (new record), C militaris var. sphaerocephala(new record), C militaris C pruinosa, Paecilomyces cicadae, and Beauveria basiana. Cemeiensis is characterized by it's superficial perithecia, and linear ascosporesmeasuring 45 ～ 60×1.5μm. The ascospores are multiseptate, with an interval of9.8 ～ 16μm between septa. C longdongensis is characterized by its vertically immersedperithecia. The secondary ascospores measure 2.4 ～ 3.6×0.5 (～ 0.6)μm. There ismycelial strand joining stromata and host.
