الوصف:

Portrait of two cells of the chrysophyte, Pseudodendromonas (Bourrelly,1953). The colorless cells are triangular in shape in lateral view and have two subequal flagella emerging from one corner curving over the anterior side. The small cytostome is located at the anterior corner of the cell opposite the insertion of the flagella. EM reveals that the cell surface is covered by organic scales produced in the Golgi apparatus. There are one or two contractile vacuoles and a single nucleus. EM is required to make identification at the species level. This genus is colonial, with the cells forming a crown at the end of a dichotomously branching stalk system. Bacterivorous. Collected from standing freshwater near Boise, Idaho. DIC.
