Cyanocatena Hindák, 1975

Holotype species: Cyanocatena planctonica Hindák

Original publication and holotype designation: Hindák, F. (1975). Einige neue und interessante Planktonblaualgen aus der Westslowakei. Arch. Hydrobiol./Algolog. Stud. 15: 330-353.

Description: Unicellular - colonial; colonies free-floating, always microscopic, irregular in outline, with few of many freely, irregularly arranged cells, enveloped by very fine, indistinct, diffluent, colorless, wide mucilage, sometimes visible only after staining. Cells pale blue-green or pale gray, without gas vesicles, almost spherical up to cylindrical, straight or slightly arcuated, widely rounded at ends, with circular, blackish ferric precipitations on the cell surface and between cells; precipitations arise often at the place of cell division and remain sometimes free within common mucilage. Cell division by binary fission, perpendicularly to the longer cell axis. After division daughter cells sometimes remain connected for a short time (with remaining iron-oxide precipitates), later separate one from another. Reproduction by the dissociation of colonies. Planktonic in eutrophic freshwater, known from the central Europe (Austria, Czechoslovakia, Germany). Very similar to some Cyanodictyon species (cf. ).

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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