Description: Cells pyriform or globose, each containing one parietal chloroplast and one pyrenoid; coenobia composed of four cells arranged in a flat plate (which later is distorted) at the angles of a square, remote from one another but connected by strands of cellwall substance; each cell bearing a scale-like fragment of mother-cell wall. Four to 16 coenobia may be united by strands of cell-wall substance; each coenobium attached at the corners of a square, but with the plane of each coenobium at right angles to the plane of the colony as a whole.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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