Description: Unicellular Chlorophyta sensu Bremer (1985) with two flagella in clockwise basal body orientation; cell wall thin with or without papilla, the single chloroplast cup-shaped, parietal and massive with ridges/grooves running parallel to the cell axis; several discontinuous pyrenoids, irregular distributed; eyespot in an anterior position; with only two apical contractile vacuoles or with many (>10) additional contractile vacuoles, distributed over the cell surface; nucleus in central or slightly anterior position. Asexual reproduction by zoospores, rotation of the protoplast by 90 before first cell division ("false transverse division") by species with only two contractile vacuoles or transverse division by species with many contractile vacuoles; partial lysis of the sporangial wall before release of zoospores. Sexual reproduction by oogamy, homothallic, proterandric; zygotes ornamented or not ornamented, green or brownish-red.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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