Description: Organisms with very variable growth habit, including short branched, uniseriate or multiseriate filaments, sarcinoid packets, cell tetrads and pairs, and single coccoid cells. Cells variously shaped: elongated, pyriform, L-shaped, oval to spherical, usually surrounded by a mucilaginous envelope. The side branches of filaments originate from the upper part of the cell near the transverse wall, and arise by lateral bulges. Cells uninucleate, containing a parietal chloroplast with one distinct pyrenoid. Asexual reproduction by biflagellate, stigma-possessing zoospores and by autospores.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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