Trochiscia naumannii Kol ( Fig. 2d, e )

References: Komárek and Fott 1983: 456, pl. 136, fig. 5. Occurrence site: Chukdong reservoir (WT 28.3℃, pH 8.3. EC 213 μs/cm).

Description: This species is unicellular or solitary, and has a spherical to subspherical shape. The cell walls are thick, with numerous short projections. The cells have a single chloroplast containing a pyrenoid, and are 20-30 μm in diameter.

Specimen: DAEJIN-20150603-1.

Remark: This species was first described by Kol (1937), but has not subsequently been clearly identified. Komárek and Fott (1983) reported this species but did not provide descriptions or original figures (only presented the figure of Kol, 1968). This species was initially classified in the family Oocystaceae , order Chlorococcales by Komárek and Fott (1983), but Guiry and Guiry (2016) included it in the family Oocystaceae and order Chlorellales in the class Trebouxiphyceae.
