Taxonomy

Description
Polyakova et al., 2023: Dark green, light green, or olive green cocci 2.7 ± 0.3–3.6 ± 0.2 μm long (min–max, 2.1–4.5 μm) and 2.4 ± 0.3–3.2 ± 0.2 μm wide (min–max, 1.5–3.7 μm). Binary fission in one plane (preferentially), or in two perpendicular planes (occasionally); single, in pairs, or in tetrads. Sheath and capsule absent, mucilage produced. Parallel rows of thylakoids stretched from cell pole to pole. Loose cell precipitate in unstirred culture; homogeneous growth in stirred culture. Colonies on 1.2% agar round, with slightly waveform edge and smooth shiny surface, moderately granular, bordered with slime. Freshwater, stenohaline: growth inhibited at ≥0.3% NaCl addition to modified BG-11 medium (1/5 nitrate amount; 0.05% total salt). PE produced; complementary CA2. Pairwise identity of 16S rRNA gene sequences with published strains of the genus Geminocystis 94.5–97.9%; species-specific nucleotide sequence and folding of D1–D1′ and B box domains of the 16S–23S ITS region.
