Cosmarium turpinii BREB. var. eximium WEST & G. S. WEST The cells are only a little longer than wide and sexangular in shape. The cell halves are strongly tapered towards the flat, weakly emarginated cell ends. The central cut ist closed and right-anglularly opened at the outside end. The cell wall wears rows of warts. In the center of each cell half there is a clearly visible hemispheric bump. Dimension: Length: 60 â 70 µm, width: 50 â 60 µm Ecology: Sometimes in plancton of lakes and ponds. Occurrence: Ubiquitous in temperate zones.
