摘　　要：对采自我国不同地区的菌寄生属标本进行分类研究,发现了该属的3个新种。鹅膏菌寄生Hypomyces amaniticola生长于鹅膏属真菌的子实体上,子囊壳埋生或半埋生于菌丝层中,橘黄色至黄褐色,卵圆形至梨形;子囊圆柱形,具8个孢子;子囊孢子长椭圆形至椭圆形,两端钝圆,无分隔,表面光滑。拟完整菌寄生H.completiopsis以牛肝菌为寄主,子囊壳橘黄色至黑褐色,梨形至近球形;子囊圆柱形,具8个孢子;子囊孢子纺锤形至披针形,两端具细尖,表面具疣。云南菌寄生H.yunnanensis子囊壳半埋生或近表生,黄褐色至褐色,梨形至近球形;子囊孢子近纺锤形,两端具细尖,1个分隔,表面具疣。提供了新种的详细宏观和微观特征描述及图示。此外,发现该属的2个中国新记录种,即小孢菌寄生H.microspermus和盘菌菌寄生H.stephanomatis,对我国材料的形态特征与原始描述进行了比较。Collections of the mycoparasitic genus Hypomyces from different regions of China were surveyed. Three new species are introduced based on samples from Yunnan Province. Hypomyces amaniticola on fruitbodies of Amanita is characterized by perithecia semi-immersed to immersed in subiculum, oval to pyriform, orange yellow to brownish yellow; cylindrical asci containing 8 spores; and long ellipsoidal to ellipsoidal ascospores which are unicellular, non-apiculate and smooth. Hypomyces completiopsis on Boletus has pyriform to subglobose, orange yellow to blackish brown perithecia; cylindrical asci with 8 spores; and fusiform to lanceolate ascospores with a verrucose surface and a conspicuous apiculus at both ends. Hypomyces yunnanensis is distinguished by perithecia semi-immersed or nearly superficial, pyriform to subglobose, yellow-brown to warm brown; and ascospores subfusiform, apiculate unequally bicellular and with a verrucose surface. Morphological features of the new species are described and illustrated comprehensively and compared with their related fungi. In addition, Hypomyces microspermus and H. stephanomatis are reported for the first time in China.
