Cells mostly longer than wide. Filaments uniseriate or multiseriate, forming branches by the division of cells perpendicularly to the main filament axis (true branching).

Difficult to distinguish from Stigonema, and other true-branched cyanobacteria. Stigonema forms branches that may are multiseriate, while uniseriate branches dominate other genera.




Generally benthic in lakes.
