Nostocaceae

The Nostocaceae is a family of cyanobacteria that forms filament-shaped colonies enclosed in mucus or a gelatinous sheath. Some genera in this family are found primarily in fresh water (such as Nostoc), while others are found primarily in salt water (such as Nodularia). Other genera (e.g. Anabaena) may be found in both fresh and salt water. [more]

Rivulariaceae

Rivulariaceae is a family of cyanobacteria within Nostocales in which the filaments (trichomes) are tapered from wider at the base to narrower at the tip. The type species is Rivularia haematites (Dc) C. A. Agard. [more]
