Pseudodidymocystis

Pseudodidymocystis is a genus of green algae in the family Scenedesmaceae.

Pseudodidymocystis consists of single cells or two-celled colonies. When in colonies, the two cells are typically oval to ellipsoidal in shape, whereas single cells are nearly spherical. The cell wall has two layers: a fibrous inner layer and an outer layer of sporopollenin which is often granulated.
