Taxonomic status: currently recognized as a distinct genus.

Description: Cells with gliding motility, spherical to ovoid, 5-12 ┬Ám in diameter and never seen as doublets or packets. Multiplication is asexual by fission. Thin extracellular matrix. Chloroplast bright red, parietal and composed of four or more lobes radiating outwardly from and around the central pyrenoid. Chloroplast lobes partially encircle the peripheral nucleus, lacking peripheral encircling thylakoid. Pyrenoid becoming elongated or multiple in old cells, surrounded by floridean starch sheath. Pyrenoid matrix containing branched thylakoids. Starch grains scattered throughout older cells. Vacuoles small, located throughout peripheral cytoplasm. Nucleus with central nucleolus. Cis-region of Golgi apparatus associated with endoplasmic reticulum and mitochondrion. The low molecular weight carbohydrates are floridoside and digeneaside. The phycobilins are B-phycoerythrin, R-phycocyanin and allophycocyanin.

Origin of description: this description is from the original publication; it may have been modified slightly.

Numbers of names and species: There are 4 species names in the database at present, of which 3 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
