Class: Prymnesiophyceae

Size: Cells 3.5-7 micron in diameter.

Color: Cells are golden brown.

Cells are spherical in shape. Two long equal flagellate emerge from the anterior end. Chromatophore parietal, saucer shaped, smooth (in young cells) and two in number. The space in between the two chromatophores is occupied by the reserved food materials such as leucosin granules and oil bobies, nucleus and contractile vacuoles are also present. Nucleus is very small and lies at the anterior end, along with the contractile vacuole. Leucosin granules are globular in shape and basal in position. In order cells these granules are very large and occupy the major portion of the cell.

Reproduction takes place by binary fission of the motile cells. Cysts with silicified walls are noticed in old culture. Palmelloid stages also occur commonly.
