Diagnosis:
Gomont (1892)
: Trichomata cylindracea, libera, evaginata, aut rarius vaginis pertenuibus, fragilibus, mucosis inclusa, interdum ad genicula constricta, haud moniliformia, pice saepius attenuata recta curvata vel plus minusve regulariter terebriformia, in speciebus nonnullis vulgo, sed non constanter, per totam longitudiem spiralia; membrana cellulae apicalis in speciebus pluribus superne incrassata.
Type species:Oscillatoria princeps Vaucher ex Gamont 1892. - About 30 species.
Descriptions:
Komárek (1992):
Filamentous; filaments simple, never branched, usually in fine, smooth, layered (but not leathery) strata (mats), microscopic or (later) macroscopic up to several cm in diameter, rarely solitary or in small groups, without sheaths, only in suboptimal (extreme) conditions (or sometimes in cultures) enveloped by thin, colourless, firm sheaths, opened at the apex. Trichomes isopolar! Straight or slightly waved, usually wider than 8 μm (up over 60 μm wide), uniserial, composed of shortly cylindrical or barrel-like (discoid) cells (always shorter than wide, usually several times), constricted or unconstricted at the cross walls, not attenuated or shortly attenuated to the ends, motile under convenient environmental conditions (waving, trembling, oscillation). Cells without aerotopes but with fine granulation (sometimes prominent at the cross walls) or with solitary granules, blue-green, brownish or pinkish, with coiled thylakoids, situated usually irregularly throughout the whole cell content. End cells widely rounded, sometimes capitate or with narrow calyptra. False branching, heterocytes and akinetes absent.
Genotype differences, molecular data:
Reproduction strategies, life cycles, cell division:
Komárek (1992): Cell division crosswise, perpendicularly to the long axis of a trichome, in a rapid sequence. Sometimes occur irregular meristematic zones. Reproduction by +/- short, motile hormogonia, which separate from the ends or from whole trichomes by help of necridic cells.
Ultrastructure:
Taxonomic position, higher hierarchy: Cyanophyceae,
Oscillatoriales, Oscillatoriaceae, Oscillatorioideae
Notes to taxonomy, misinterpretations:
Ecology, ecophysiology, ecological significance:
Komárek (1992): All species grow in mats on different substrates (mud, stones, sandy bottom, etc.), mainly in shallow water biotopes, in littoral regions of freshwater reservoirs and seas, in pools, rarely on wet soils. Characteristic are the "floating Oscillatorieta", developing primarily benthic, later floating as macroscopic clusters on the water surface (sometimes in masses). Distribution allover the world, but several species have the geographically limited areas of distribution.
Gomont (1892): Plantae hydrophilae, thermales vel halophilae, raro et casu terram humidam incolenles.
