Scenedesmus denticulatus
Lagerheim var. denticulatus
= Desmodesmus denticulatus (Lagerheim) E. Hegewald
Genus: Colonies of 4 (or 2, 8, 16) cells attached side by side, arranged linearly or zigzag;
cell body elliptical or spindle or crescent in shape; terminal cells with spiny projections in many species;
cell wall usually smooth, but in some species granulated or dented or ridged
(Illustrations of The Japanese Fresh-water Algae, 1977).
Species [ var. denticulatus ]:
Colonies of 4-8 cells arranged in a slightly zigzag pattern or straight;
cells at both ends have 2-3 dented projections at both termini,
inner cells have such projections at only one terminus;
cell body 10-15 μm long, 5-10 μm diam.
(Illustrations of The Japanese Fresh-water Algae, 1977).
