Description of CochliopodiumDiscoid or spherical in shape with a central granular hump partly or completely surrounded by a distinctive hyaline margin. With a surface layer (tectum) of fine plates or microscales. The scales are visible under the light microscope and appear as a regular, punctate pattern on the hyaline border which surrounds the granular hump of the cell. In a few isolates, this border is incomplete at the posterior. Distinct tubular configuration of tectum around pseudopodial bases of floating forms. Short clear pseudopodia sometimes furcated (branching) - frequently project from the hyaline border and trailing posterior filaments are found in some species. Cytoplasm with a single nucleus (usually vesicular) and several truncate bipyramidal crystals. This genus is common. No cyst known.
