Marine. Filamentous; unbranched thallus. Erdschreiber’s medium.

Characterized by reddish plastids (rhodoplasts).

Freshwater. Unicellular; heart-shaped cell. Soil-water medium.

Characterized by a lack of rigid cellulosic walls, instead these organisms have pellicles made of protein. They store paramylon instead of starch.
