Korschik。（Pascher, 1927, p. 271）和C. minutissima Korschik。土壤11；后两项是这个国家的新纪录。亚甲基蓝染色显示，桔梗的部分个体呈弯曲状，而细碎的部分个体呈微小的乳头状。新种如下：亚纲衣藻（Chlamydomonas subangulosa n. sp.）1 c)。细胞宽椭球状，两端圆形，前部具一宽平的乳头。膜薄。叶绿体杯状，在老细胞中微裂，基部具大卵形，偶有棱角，类核细胞占细胞的一半以上。核在类核蛋白上方。眼斑小，近前端。鞭毛略短于身体。师通常分为4个，第一个师纵向。具有无结构粘液的掌叶期。细胞16-20 n宽；20-4英寸长。
Korschik.(Pascher, 1927, p. 271) in the same soil, and C. minutissima Korschik. in soil 11; the last two are new records for this country. Some of the individuals of C. platyrhyncha were curved, while those of C. minutissima showed a minute papilla on staining with methylene blue. The new species are as follows:Chlamydomonas subangulosa n. sp.(Fig. 1, c). Cells broadly ellipsoidal, both ends rounded, the anterior with a broad flat papilla. Membrane thin. Chloroplast cup-shaped, faintly lobed in the older cells, the basal portion with the large oval, occasionally angular, pyrenoid filling more than half the cell. Nucleus above the pyrenoid. Eye-spot small, near the anterior end. Flagella slightly shorter than the body. Division usually into 4, first division longitudinal. Palmella-stages with structureless mucilage. Cells 16-20 n broad; 20-4¡ jl long.
