摘　　要：报道了团藻目衣藻科拟衣藻属一新种。此种从中国科学院武汉植物研究所一浇园粪缸中采得 ,在分离室内单种培养过程中 ,对其形态学和生活史进行了研究。营养细胞具多个盘状色素体 ,与拟衣藻属已知的种类有明显的差别。经培养观察 ,作者发现除细胞分裂、无性生殖外 ,还有同宗异配式有性生殖 ,在生活史各阶段该藻叶绿体中均未见蛋白核 ,因此 ,拟衣藻作为分类单元是一个有效的属。This paper deals with the morphology and life cycle of a new species of Chloromonas sinica H.J.Hu et C.T.Yin (Chlamydomanaceae,Volvocales) from Wuhan,P.R.China.The alga (smaller discoid chloroplast and special habitate ) seems to be morphologically rather distinct from the other members of Genus Chloromonas. The investigation of the life history of this alga in the cultural condition reveals vegetative division,asexual reproduction and sexual reproduction which is homothallic,heterogametic and produces smaller male gametes and larger female gametes.The study has proved that there are not pyrenoid on the chloroplast in the all stages of the life history of this alga.Therefore,Chloromonas as a taxa is valid genus.
