Koliellaceae

Koliellaceae is a family of green algae in the order Prasiolales.

Koliellaceae was circumscribed by František Hindák in 1996 to include various green algae that reproduce mainly by simple cell division. Cells are solitary or found in small colonies or filaments. Cells are cylindrical to spherical, with or without a layer of mucilage. The cell wall may be smooth or covered with granulations. Cells contain a single, parietal chloroplast with or without a pyrenoid. Reproduction is typically by cell division into two equally sized cells; however, aplanospores or zoospores may be formed occasionally. Sexual reproduction is oogamous.
