Tetrachlorella tetrachlorelloides (Buck) Hindak.

Occurrence site: Seogangdaegyo, Han River (WT 30℃, EC 376 μs/cm).

Description: Colonies composed of 2, 4, 6, 8 or 16 cells, apparently lacking a mucilaginous sheath, but with a persistent mother cell wall. Cells ellipsoidal or oval, surrounded by a distinct mother cell wall, 12-16 μm in length and 8-13 μm in width.

Distribution: Eutrophic lakes of England, Austria, Switzerland ( Komárek and Fott, 1983).

Specimen: NIBRCL0000112291; DAJIN-201500709-1.

Remark: This species was included in the family Oocystaceae , order Chlorococcales by Komarek and Fott (1983), but was moved to the family Oocystaceae , order Chlorellales , class Trebouxiophyceae by Guiry and Guiry (2016). Hindak (1980) included this species in Tetrachlorella Korshikov as a synonym, but Komarek and Fott (1983) transferred it into Fotterella from Tetrachlorella , which has solitary or architectonie of cells in colonies.
