Growth diffuse, but often with meristematic regions in lower part of filaments. Cells generally short, with one or two clusters of elongate phaeoplasts, radiating in an axile position and often appearing stellate, each phaeoplast with a terminal pyrenoid in the centre of the stellate group.

Reproduction: Reproduction by unilocular sporangia formed in intercalary series in the filaments, with occasional cells dividing longitudinally; plurilocular organs unknown.
