Morphology<\/h2>\n

Filaments usually in loose flake-like clusters, either floating or attached to substrate; rarely solitary; rarely forming a compact thallus. Filaments typically long and flexuous or with fine waves; rarely almost straight; not attenuated at the ends; not capitate; only rarely with some occasional false branching. Sheaths are produced facultatively, and frequency of sheath production varies with species and environmental conditions; sheaths are firm, thin, and transparent. Trichomes 0.5-3.5 \u03bcm wide; constricted or unconstricted at crosswalls; not motile or with indistinct trembling (or motile hormogonia). Cells cylindrical; typically isodiametric or shorter than wide (or distinctly longer than wide, though such species may represent a distinct genus); cell content homogeneous; gas vesicles absent; apical cells mostly rounded or rounded-conical, sometimes slightly narrowed.<\/p>\n

This is a large and varied genus, containing distinct sub-groups (distinguished morphologically as well as phylogenetically and ecologically); (further) division into multiple genera is expected.<\/p>\n

Ecology<\/h2>\n

Very common. Reported from a wide variety of habitat types, including freshwater and saltwater; soil, subaerophytic, and aquatic environments; mineral and thermal springs.<\/p>\n
