Phormidium is a common genus of cyanobacteria with a cosmopolitan distribution. This genus is in the family Oscillatoriaceae. Species in this genus will produce a range of cyanotoxins. Under favorable conditions, Phormidium forms continuous and large mats, which are documented to harbor various species of bacteria or algae.
As a result of recent genetic analyses, several new genera were erected from this genus, e.g. Potamolinea.
