Cells arranged in uniseriate, unbranched chains; in larger thalli chains s-shaped or spirally twisted. Cells spherical, 1.2-2.8 &m or 3-8 &m diameter, closely adjoining in structureless mucilage; cell walls without obvious ornamentation. Cells uninucleate with single, cup-shaped, parietal chloroplast; pyrenoid present or absent. Asexual reproduction by autospores, 3-4 &m diameter (in large celled species), with 2-8 (usually 4) spores per sporangium; spores released by dissolution of cell wall. Flagellated stages absent. Sexual reproduction unknown. Catenococcus planktonic, known only from Czecholovakia in eutrophic lakes and rivers. Species distinguished on cell size, and presence/absence of pyrenoid.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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