Siderocelis estheriana Hortobagyi ( Fig. 3 e-g)

References: Komárek and Fott 1983: 561, pl. 162, fig. 2; Hajdu 1975: 29, Hortobagyi 1957: 341, fig. 1.

Synonym: Coenocystis estheriana (Hortobagyi) Budapest.

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

Description: This species occurs as unicells or groups of four cells. The cells are oval or ellipsoidal in shape, and slightly concave at the sides. The cell wall is relatively thick, light brown, and the surface is covered with fine granules. A chloroplast is located in the center of each cell, and contains a pyrenoid. The cells are 11-16 μm in length and 7-14 μm in width.

Distribution: Hungary ( Hortobagyi, 1957; Hajdu, 1975; Komárek and Fott, 1983).

Specimen: DAEJIN-20150709-2.

Remark: This species is first reported by Hortobagyi (1948). Hajdu (1975) reported Coenocystis estheriana as the new species and merged S. estheriana into C. estheriana . However, any other species in the family Radiococcaceae were not granules on the cell wall surface. Therefore Komárek and Fott (1983) replaced C. estheriana into S. estheriana .
