Diagnosis:
Řeháková et al. (2007): Genus cyanoprocaryoticum generis Nostoc similis. Coloniae microscopicae in natura, subsphaericae, ellipsoideae vel irregulares, tegumentis firmis et mucilaginosis circumdatae, despues in seriebus macroscopicis, repentis vel erectis ordinatae in vitro; series subcoloniis pseudofilamentosae, de subcoloniis et microcoloniis compositae, praecipue in vitro. Cellulae subsphaericae, in coloniis in trichomas uniseriatas vel pluriseriatas et valde flexuosas conjunctae, ad dissepimenta valde constrictae, vel in aggregationis densis agglomeratae. Heterocytae semper terminales, vel laterales in agglomerationis, heterocytae intercalares raris. Coloniae iuvenes cum heterocytis utrinque terminalibus. Reproductio disintegratione coloniis, cellulis solitariis liberantis de coloniis, vel hormogoniis
paulocellularibus. Hormogoniae germinantes sine heterocytis, saepe cum cellulis binis dilatatis intercalaribus; hormogoniae plerumque acute flexae inter cellulis dilatatis.

Descriptions:
Řeháková et al. (2007): Cyanobacterial genus similar to the genus Nostoc. Colonies microscopic in nature, subsphaerical, ellipsoid to irregular, surrounded by a firm and mucilaginous covering. Series of subcolonies create macroscopic, upright or horizontal pseudofilaments in liquid culture. Cells subsphaerical, joined into uniseriate trichomes or strongly flexuous pleuroseriate colonies, strongly constricted at the crosswalls, or agglomerated into dense aggregations. Heterocytes mainly terminal, or lateral in agglomerations, with intercalary heterocytes very rare. Young colonies only with terminal heterocytes. Reproduction with colonial disintegration, by free solitary cells (hormocytes) or multicelled hormogonia. Hormogonia germinating without heterocytes, often with intercalary
paired widened cells which often cause acute bending of the hormogonia.
