A 北京通州、内蒙古赤峰、辽宁沈阳、江苏徐州、江西遂州、本实验室
Tongzhou district, Beijing; Chifeng, Inner Mongolia; Shenyang, Liaoning; Xuzhou, Jiangsu; Suizhou, Jiangxi; this laboratory
栽培料表面至子实体任意部位
Surface of the cultures and any parts of the fruiting bodies
多发生在蛹虫草生长发育后期;在子实体上形成白色菌落,覆盖于其表面,影响子实体发育,后期子实体倒伏,完全被白毛覆盖
The disease occurred at the late stage of the growth and development of C. militaris. White colonies covered the surface of fruiting bodies, affecting development of the fruiting bodies. The fruiting bodies collapsed and were completely covered by white mildew finally

B 北京通州、内蒙古赤峰、本实验室
Tongzhou district, Beijing; Chifeng, Inner Mongolia; this laboratory
栽培料表面至子实体基部
Surface of the cultures and base of the fruiting bodies
主要发病在原基形成之后,气生菌丝旺盛,菌丝体白色棉絮状,从基部向上蔓延,直至将整个蛹虫草子实体包围;被病原菌包围的子实体由深橘黄色变为浅橘黄色;侵染后期,子实体枯死
The disease mainly occurred after primordium formation. The mycelia were white, strong and cotton-like, and spread until covering the whole fruiting bodies. The infected fruiting bodies changed from dark orange into light orange, wilted and died eventually

Surface of the cultures and base of the fruiting bodies
主要发病在原基形成之后,棉絮状菌丝迅速向上蔓延,造成子实体基部变软,子实体倒伏
The disease mainly occurred after primordium formation. Cotton-like mycelia spread upward rapidly, resulting in softening of the base and lodging of the fruiting bodies

E
内蒙古赤峰
Chifeng, Inner Mongolia
栽培料表面至子实体基部
Surface of the cultures and base of the fruiting bodies
气生菌丝旺盛,呈白色丝绵状,短时间内从基部向上覆盖蛹虫草子实体,侵染状态下未见孢子产生,仅依靠菌丝致病
Aerial mycelia were vigorous and white, covering the fruiting bodies from the base to the top in a short time. No spore was found

F 北京通州、江苏徐州
Tongzhou district, Beijing; Xuzhou, Jiangsu
栽培料表面至子实体基部
Surface of the cultures and base of the fruiting bodies
发生于栽培料表面,病原菌丝迅速向四周蔓延,同时沿子实体向上蔓延,初始为白色,后产生分生孢子变成绿色,侵染后期整个子实体变成绿色
The disease occurred on the surfaces of media, spreading rapidly to the fruiting bodies. The mycelia were white at the beginning, then turned green because of conidiation, and the whole fruiting body turned green finally

G 本实验室
This laboratory
栽培料表面
Surface of the cultures
可侵染蛹虫草菌丝,侵染部位不形成原基;其仅在侵染部位蔓延,不会造成病害的大范围爆发
The pathogen infected the mycelia of C. militaris, and no primordium was formed in the infected sites. The disease was limited partially and would not cause a large-scale outbreak
