Description From Basionym: Synechococcus lividus Copeland, Ann. N. Y. Acad. Sci. 1936: 56, 1936: Cyanobacterial cells solitary, in irregular agglomerations, or in short, few–celled indistinct rows, narrow, with rounded ends, usually several times longer than wide, straight, strictly cylindrical or slightly curved or arcuated, without prominent slime envelopes. Cell division perpendicular in one plane in subsequent generations, symmetrical or slightly asymmetrical, with daughter cells usually separating soon after division, less frequently forming short rows of a few cells. Cytoplasm sometimes with visible narrowed peripheral chromatoplasma (= few, ± parietal thylakoids), usually pale or intensely olive–green or blue–green, without aerotopes, usually with solitary granules situated in the terminal parts of cells. – Ecology: Mostly in thermal springs from 20–40 °C (up to possibly over 80 °C, comp. Copeland 1936 under Synechococcus; other habitats not yet confirmed); in such localities probably a cosmopolitan genus. From Komarek 2020.
Cells long rod-shaped, straight or curved, 5-15 (32) x 1.2-2.2 µm; thermobiotic species at high temperatures (usually more than 50°C); several taxa were described, which are probably morphotypes and/or ecotypes of S. lividus (var. circatus Copeland 1936, var. siderophilus Copeland 1936, var. non-granulatus Emoto et Hirose 1939, S. arcuatus Copeland 1936, S. vesus Copeland 1936, S. vesus var. non-granulatus Emoto et Hirose 1940, S. sublividus Emoto et Yoneda 1940, S. praelongus Emoto et Yoneda 1940). S. boshardii Skuja 1932 (described from hot springs in high central Asia) belongs possibly also to this group; in that case it seems justified to conserve the epithet lividus. S. lividus is known from numerous hot springs all over the world (Japan, New Zealand, USA, Zimbabwe, etc.), but not yet recorded from Europe.
