Abstract

Ophiocordyceps is the largest genus in Ophiocordycipitaceae and has a broad distribution with high diversity in subtropical and tropical regions. In this study, two new species, pathogenic on lepidopteran larvae are introduced, based on morphological observation and molecular phylogeny. Ophiocordycepsfenggangensissp. nov. is characterised by having fibrous, stalked stroma with a sterile tip, immersed perithecia, cylindrical asci and filiform ascospores disarticulating into secondary spores. Ophiocordycepsliangiisp. nov. has the characteristics of fibrous, brown, stipitate, filiform stroma, superficial perithecia, cylindrical asci and cylindrical-filiform, non-disarticulating ascospores. A new combination Ophiocordycepsmusicaudata (syn. Cordycepsmusicaudata) is established employing molecular analysis and morphological characteristics. Ophiocordycepsmusicaudata is characterised by wiry, stipitate, solitary, paired to multiple stromata, yellowish, branched fertile part, brown stipe, immersed perithecia, cylindrical asci and cylindrical-filiform, non-disarticulating ascospores.

贵州的蛇虫草（Hypocreales，Ophiocordycipitaceae）的两个新种和一个新组合。

麦角虫属是麦角虫科（Ophiocordycipitaceae）中最大的属，分布广泛，在亚热带和热带地区具有很高的多样性。本研究根据形态学观察和分子系统发育，介绍了两种对鳞翅目幼虫具有致病性的新种。Ophiocordycepsfenggangensissp.nov.的特征是具有纤维状、带柄的基质，顶端不育，有浸泡的包囊，圆柱形的子囊和丝状的子囊孢子分裂成次级孢子。Ophiocordycepsliangiisp.nov.具有纤维状、棕色、具柄、丝状基质、表层珠孔、圆柱形子囊和圆柱丝状、不脱节的腹孢子等特征。利用分子分析和形态特征，建立了一个新的组合 Ophiocordycepsmusicaudata（同 Cordycepsmusicaudata）。Ophiocordycepsmusicaudata 的特征是：具柔毛、具柄、单生、成对或多生的基质，淡黄色、分枝的可育部分，棕色柄，沉浸的外生菌丝，圆柱形的子囊和圆柱丝状、不脱节的外生孢子。
