Rivularia is a genus of cyanobacteria of the familia Rivulariaceae.[1]
Description
Rivularia is found growing on submerged stones, moist rocks and on damp soils near the riverside. The alga 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 aptical portion which is whip or tail like consisting of a row of small cells. Akinetes are absent in Rivularia. Rivularia multiplies with the aid of hormogonia and heterocyst.
