Synechocystis Sauvageau, 1892
Holotype species: Synechocystis aquatilis Sauvageau
Original publication and holotype designation: Sauvageau, C. (1892). Sur les algues d'eau douce recoltées en Algérie pendant le session de la Societé Botanique en 1892. Bulletin de la Société Botanique de France 39: civ-cxxviii, pl. VI.
Description: Unicellular; cells solitary or agglomerated, but without common mucilage, spherical or slightly widely oval before division, sometimes enveloped by own thin, fine, colorless, diffluent mucilaginous envelope (staining !), with homogeneous content or with several prominent granules, sometimes with visible chromatoplasm, pale blue-green, olive-green, bright green or pinkish. Cell division (pinching) always in two perpendicular planes in successive generations (recognizable only on solid substrates); daughter cells separate soon after division and grow into the original size and shape before next binary fission. Reproduction by solitary cells. Several species are planktonic in fresh water reservoirs or in saline or sea waters, other grow in metaphyton of pools, of thermal and mineral springs, of saline (brackish) swamps or in moors. The "Marine-cluster of Synechocystis", defined by Waterbury (1989), belongs evidently to this genus. The "Aphanocapsa"-species found within hollow hairs of polar bears in zoos (comp. Lewin 1979) is evidently also a Synechocystis-species.

Verification of Data

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.
Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
