Pseudokirchneriella

Pseudokirchneriella is a genus of green algae in the family Selenastraceae. It is found as phytoplankton in freshwater ponds, lakes, and pools. It has been reported from Europe and North America.

Description
Pseudokirchneriella usually consists of colonies of cells within a thin layer of mucilage. Usually two to 32 are present within a colony. Cells are crescent-shaped, with pointed to rounded ends. The cell wall is uniformly smooth without any ornamentation. Cells are uninucleate (with a single nucleus) and a single parietal chloroplast. Cells are irregularly distributed within the mucilage.

Pseudokirchneriella was split off from its congener Kirchneriella by the absence of a pyrenoid. Not all authors recognize the two genera as being distinct.
