Rivularia is a genus of cyanobacteria of the family Rivulariaceae.[1]
Description
Rivularia is found growing on submerged stones, moist rocks, and damp soils near the riverside. It is found in colonies, and the trichomes are radially arranged within a colony, with each trichome wholly or partially surrounded by a gelatinous sheet. The trichomes have a basal heterocyst. Each trichome has a narrow aptic portion which is whip- or tail-like consisting of a row of small cells. Akinetes are absent in Rivularia. The species multiply with the aid of hormogonia and heterocyst.
