The cells ovoidal, while budding the wall structure is entroblastic. Reproduction by multilateral budding. It is not form ascospores or ballistospores; on malt agar red carotenoid pigments is synthesized.

该菌株细胞卵圆，出芽时胞壁结构为内分芽型，多端芽殖，不产生子囊孢子和掷孢子；在麦芽汁琼脂上产生红色胡萝卜素，颜色反应阳性，菌落平滑，有光泽，质地软而呈粘液状，不发酵任何糖，能同化麦芽糖、蔗糖、乳糖、棉子糖、松三糖和硝酸钾，能分解尿素；细胞水解物中含甘露糖、葡萄糖和半乳糖。

The pathogen was i dentified as Botryosphaeria ribis,which belongs to Ascomycotina.The asexual pathogen was Phoma moricola Sacc,which belongs to Deuteromycotina. The stitable conditions for germ feat growth w ere temperature: 30, pH:7.0, relative humidity 98% in 3% maltose. Carbendazim and asomate could control thi s disease effectively.

研究表明：（1）该病是由子囊菌亚门茶子葡萄座腔菌所致，无性为半知菌亚门桑茎点菌；（2）该菌适宜生长的温度为30℃，pH为7.0 ；3%麦芽糖和 98%相对湿度对无性孢子萌发极为有利；（3）多菌灵和福美砷能有效控制该病。

Microscopically, globular or ovoid cells, a number of round, ovoid shaped endospores could be observed. No hypha, ascus or blastic conidia was found upon cultivation on SDA. Based on the morphological characteristics, this isolate could be identified as Prototheca species.

结果 该菌在25℃、37℃均可生长，沙堡弱培养基、马铃薯培养基见光滑湿润的白色酵母样菌落，镜下圆形、椭圆形的孢子及裂殖成圆形或不规则形的内孢子，无菌丝、子囊、芽孢，根据形态学特征鉴定为无绿藻。

Saccharomycetales An order of the Ascomycota, containing the yeasts, in which the mycelium is poorly developed or absent, and the vegetative stage comprises mainly single cells that reproduce asexually by duding or fission.

酵母菌：隶属子囊菌纲，包括酵母。其特点为菌丝体发育不良或完全缺失，营养体主要是进行出芽生殖或裂殖的单细胞。

Sclerotiorum were screened out, sclerotia of which could germi-nate to form apothecia at 20℃ without any conditioning.

首先从158个单菌核分离物中筛选出了6个能够在高温（20℃）下直接形成子囊盘的核盘菌菌株。

The release and survival of ascospores of a UK Sclerotinia sclerotiorum isolate were studied.
