Description: Cells with gliding motility, spherical to ovoid, 5-12 µm 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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
