Calothrix
RANK: Genus
TAXONOMY: Bacteria -> Terrabacteria group -> Cyanobacteria/Melainabacteria group -> Cyanobacteria -> Nostocales -> Rivulariaceae -> Calothrix
OVERVIEW:
Mature ensheathed trichomes exhibit a pronounced degree of tapering. The motile hormogonia are generally very short, exhibit a significantly reduced cell diameter, and are sheathless (or less ensheathed). They give rise to trichomes that differentiate a basal, one-pored heterocyst. False branching frequent. Akinetes lacking in most members. All are freshwater, soil, or hot spring inhabitants.
