  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.
