报道了甘肃省新发现的蛇形虫草属真菌细蛇形虫草，并对其有性型（Ophiocordycepsgracilis）和无性型羽束孢（Paraisaria dubia）的形态特征进行了描述。采集自甘肃夏河的细蛇形虫草的寄主为一种蝠蛾幼虫（Hepialus sp．），采集地海拔3500m。僵虫体表包裹黄褐色菌索；子座单生，从僵虫头前端或头背部长出，可孕部卵圆形或近球形，暗黄褐色，柄部淡黄褐色，圆柱形；子囊壳褐色，埋生，袋囊状或瓶状，子座少见。

In this paper, Ophiocordyceps gracilis is reported as a new record in Gansu Province, and the morpha both teleomorph on Hepialus larva and anamorph on culture are described. Samples were collected from Xiahe County with altitude of 3 500 m. Infected-larvae are covered by several yellow brown synnemata. Stroma are produced in solitary per host, usually from head or thorax region. Stroma consists of a stout cylindrical stipe, with a pale yellow brown,and ovoid to subglobose,dark yellow brown-colored head. Perithecia are completely immersed in head, brown-colored, saccate or flask shaped. Stroma are formed infrequently.
