Diagnosis:
Gomont(1892): Fila vaginata, libera, simplicia, nunc caespitosa, nunc in stratum floccosum vel pannosum intricata. Vaginae firmae, tenues aut, aetate provecta, crassae et lamellosae, hyalinae, rarius luteo-fuscae. Trichomata in speciebus nonnullis ad genicula constricta, apice recta, aequalia aut leviter attenuata; membrana cellulae apicalis nonnunquam in calyptram incrassata.
Type species: Lyngbya confervoidesC. Agardh ex Gomont, 1892: - About 30 species.
Descriptions:
Komárek (1992):Filamentous; filaments thick, rarely solitary, usually connected into thick, layered, sometimes leathery strata (mats), rarely tangled into free clusters of coiled filaments, usually macroscopic, up to several cm or dm in diameter, with firm sheaths, which are sometimes layered or stratified and brownish coloured, opened at the ends; very rarely without sheaths (usually only reproduction hormogonia); unbranched or slightly falsely branched with short and sporadical branches. Trichomes
isopolar, straight or slightly waved, thick (5.5-60 um), uniserial, composed of shortly cylindrical or barrel-shaped discoid tells, unconstricted or constricted at the cross walls, not attenuated or attenuated to the ends, not motile or slightly motile (but with motile hormogonia !). Cells very short, always shorter (usually several times) than long, without or (rarely) with facultative aerotopes, usually finely granulated, sometimes more at the cross walls; cell content blue-green, olive green, yellowish, brownish or pinkish, with coiled tylakoids, situated more or less over the whole cell content; end cell with thickened outer cell wall or with prominent calyptra. 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, usually in a rapid sequence. Sometimes irregular meristematic zones. Reproduction by +/- short, motile hormogonia, which separate from trichomes by help of necridic cells. Disintegration of mats.
Ultrastructure:
Taxonomic position, higher hierarchy: Cyanophyceae,
Oscillatoriales, Oscillatoriaceae, Oscillatorioideae
Notes to taxonomy, misinterpretations:
Ecology, ecophysiology, ecological significance:
Komárek (1992): Usually growing in mats covering different subaerophytic or submerse substrates, several species are marine or brackish. Rarely occur in clusters of tangled filaments in metaphyton of not very polluted water bodies with_numerous water plants. Few species occur in plankton as solitary trichomes (rarely -L. birgei, etc.). Common all over the world (mainly the halophilic species).
Gomont (1892): Plantae aquae salsae, dulcis aut thermalis, nunquam terrestres.
