Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Komárek, J., Kastovsky, J., Mares, J. & Johansen, J.R. (2014). Taxonomic classification of cyanoprokaryotes (cyanobacterial genera) 2014, using a polyphasic approach. Preslia 86: 295-335.

Taxonomic notes
A study by Pietrasiak et al. (2014) "confirms the placement of the genus in the Phormidiaceae based upon phylogenetic analysis of molecular sequence data, and establishes the genus as unique from and unrelated to Schizothrix". - (6 Feb 2015) - Wendy Guiry

Numbers of names and species: There are 19 species names in the database at present, of which 17 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..

Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.
