摘要
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(Ophiocordyceps graci-lis)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(Hepialussp.),采集地海拔3 500 m。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.
