Portrait of Dictyosphaerium pulchellum (Nägeli,1849), a colonial green alga. The small cells are ovoid to reniform and are borne at the ends of colorless branching threads in groups of four. The threads are remnants of parental cell walls. Each cell has a cup-shaped chloroplast and solitary pyrenoid.The entire colony is embedded in a nearly invisible spherical gelatinous matrix. Collected from a freshwater pond near Boise, Idaho June 2004. DIC optics.

Dictyosphaerium pulchellum is a common chlorophyte of Lake Kinneret, relatively more abundant in winter, but never dominant. This specimen was sampled at the shore of the lake in March 2006.

Dictyosphaerium pulchellum is a common chlorophyte (Chlorococcales) of Lake Kinneret, relatively more abundant in winter, never abundant or dominant. Note that the sphaerical cells are in clusters of 4, attached by parental cell wall fragments radiating from a common center. The chloroplasts are parietal and cup shaped with a single pyrenoid. This specimen was sampled at the shore of the lake in March 2006.
