Cyanosarcina Kovácik, 1988

Holotype species: Cyanosarcina fontana Kovácik

Original publication and holotype designation: Kovácik, L. (1988). Cell division in simple coccal cyanophytes. Algological Studies/Archiv für Hydrobiologie, Supplement Volumes 50-53: 149-190.

Description: Unicellular-colonial; colonies microscopic, 2-16-multicelled, sarcinoid, up to 50 _m in diam., later usually grouped into rich aggregations of colonies, Chroococcus-like when young, later in characteristic packet-like formations with more or less cubically packed cells, enveloped usually by narrow, tight, fine or firm, colorless, sometimes slightly lamellated gelatinous envelope. Cells spherical, oval and hemispherical when young, later irregular, polygonal with rounded corners, usually densely agglomerated, flattened at the sides neighboring to other cells; cell content blue-green or pinkish, sometimes slightly granular. Division of cells first in 3 directions perpendicular to each other in successive generations, later slightly irregular; each daughter cell dividing later more or less in 3 perpendicular planes, but daughter cells remaining gathered to packet-like sarcinoid formations. Nanocytes absent. Multiplication by the dissociation of colonies. Several species growing in metaphyton and among detritus in stagnant or streaming, usually clear waters, sometimes with plenty of aquatic plants, one species is known from moors, one is subaerophytic, three are known only from tropics, 2 were described from thermal springs. The type species is known from the periphyton of a spring with cold (stenothermal) water.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
