Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Komárek, J. & Anagnostidis, K. (1999). Cyanoprokaryota. 1. Chroococcales. In: Süßwasserflora von Mitteleuropa. Begründet von A. Pascher. Band 19/1. (Ettl, H., Gärtner, G., Heynig, H. & Mollenhauer, D. Eds), pp. 1-548. Heidelberg & Berlin: Spektrum, Akademischer Verlag.

Description: Unicellular - colonial; colonies more or less spherical, microscopic, sarcinoid, not polarized, later multicellular, packet-like or sarcinoid, grouped usually densely in irregular agglomerations, enveloped by narrow, tight, fine or firm, colorless, sometimes slightly lamellated envelopes. Cells irregular spherical, later irregular, more or less polygonal with rounded corners; cell content blue-green, olive-green, yellowish or reddish, with solitary granules. Division of cells in three or more directions in successive generations, the daughter cells do not grow into original shape of the mother cell; several cells divide in distinct phases of life cycle (under special conditions) into motile nanocytes. In metaphyton and periphyton in submersed habitats among algae and water plants, in hot and mineral springs; most species occur in aerophytic biotopes (wet rocks, tree trunks), including the type species. Distribution little known, but many species probably are limited due to their special ecology.

Numbers of names and species: There are 20 species names in the database at present, as well as 3 infraspecific names. Of the species names, 11 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
