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.

Description: Unicellular-colonial; colonies microscopic, containing relatively few cells, mucilaginous, with more or less elongated cells, disposed freely, distant from one another, sometimes oriented more or less in one direction; colonial slime colorless, without structure or very finely and indistinctly, irregularly concentrically lamellated, fine, sometimes diffluent at the margin. Sometimes few small colonies clustered together. Cells spindle-like, narrowed to both ends, pointed, rounded-pointed or narrowed-rounded, straight or curved, with pale blue-green or gray-blue, homogeneous content. Involution cells filament-like. Cell division (binary fission) in two, perpendicular to the longer axis of cells, in the middle of cells or slightly excentrically in involution cells. Cells separate soon from one another. Reproduction by dissociation of colonies and by solitary cells. Most species planktonic (usually in large lakes) or living in metaphyton of clear water bodies, one species known only from tropics. One species is cryosestonic from spring and summer snow fields.

Numbers of names and species: There are 14 species names in the database at present, of which 13 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.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
