| Diagnosis:
|
| Type species: Leptolyngbya boryana (Gomont) Anagnostidis et Komárek 1988. - Very common genus with many described species (about 80), which all need taxonomic re-evaluation and definition of diacritical features; many species were described under the generic names "Lyngbya", "Phormidium" and "Plectonema".
|
Descriptions:
Komárek (1992): Filamentous; filaments long, solitary or coiled into clusters and fine mats (which are sometimes up to macroscopic and several cm in diameter), arcuated, waved or intensely coiled, isopolar, thin, fine, 0.5-3.2 um wide, with simple, thin but firm, usually colourless facultative sheaths opened at the apical end; sheaths joined to the trichomes or slightly distant from them, enveloping only one, very rarely (in short sections) two trichomes; rarely up to very rarely false branching (more common under special cultivation conditions), usually with only one lateral branch. Trichomes fine, cylindrical, usually not attenuated to the ends or slightly attenuated, with rounded or conical apical cells, not constricted or constricted at the cross walls, immotile. Cells +/- isodiametrical or longer than wide (up to several times), cylindrical, with +/- homogeneous content, without aerotopes, rarely with scarce prominent granules, pale blue-green, greyish, olive-green, yellowish or reddish; end cells without thickened cell walls or calyptras. Heterocytes and akinetes are absent.

Reproduction strategies, life cycles,
cell division:
Komárek (1992): Cells divide by +/- symmetrical (rarely asymmetrical) crosswise binary fission, cells grow into original size before next division. Reproduction by motile (?) hormogonia, liberating from trichomes at their ends, fragmentated without help of typical necridic cells, but sometimes after death of sacrifying cells.

Ecology, ecophysiology, ecological significance:
Komárek (1992): Leptolyngbya species are very common in soils and in periphyton and metaphyton of freshwater and halophilous (marine) biotopes, several species are known from thermal and mineral springs or from aerophytic rocky sites or walls; characteristic species grow endogloeic in
mucilage and in colonial slime of other algae. They grow well in cultures and are available for cultivation, one strain of "Plectonema boryanum" (=Leptolyngbya boryanum) was used as a model strain for bioassays. Taxonomy is not well known in respect of their morphological simplicity.
