Color: Pale blue green, yellowish green or brownish green.

Thalli forming minute patches or dots, later becoming membranous or crustaceous-shaped. The cells cylindrical or with small constrictions at the nodes, mostly isodiametric. Sheaths thin and colorless. Heterocyst somewhat larger than the vegetative cells, spherical, at the end of short, cylindrical branches or intercalary. Filaments 6-10 µm in diameter, variously bent, creeping, branches differentiated into two distinct types: long branch ending in a long hair and short branch only with 1-3 cells, often with a spherical heterocyst at its apex. Trichomes 3.5-6.0 µm in diameter. Heterocyst 6-18 µm in diameter. Cells 4-8 µm in length, quadrate or cylindrical.

Plants producing a dense mass of anastomosing filaments within the surface layers of mollusc and barnacle shell, calcareous annelid tubes and bryozoan tests, and other forms of limestone.
