Description: Erect, flat, soft-membranous to cartilaginous, usually flabellately, laciniately or more or less pinnately branched in one plane. Stipe short or absent. Holdfast discoid. Margin smooth, ruffled, or with protuberances. Medulla of large, isodiametric cells surrounded by chains of small cells. Cortex relatively thick, of isodiametric cells, progressively smaller toward cuticle. Outermost cells uninucleate; other cells multinucleate. Dioecious, where known. One to several 3-celled carpogonial branches borne on a supporting cell that can bear several lobed subsidiary cells and that serves as the auxiliary cell after fertilization. Fusion cell formed from subsidiary cell, supporting cell and first cell of carpogonial branche(es) after fertilization, and gonimoblast filaments initiated directly from fusion cell. Carposporangia produced in clusters or chains from gonimoblast. Cystocarps slightly to distinctly protuberant. Pericarp and carpostome present. Spermatangia superficial. Tetrasporophyte isomorphic. Tetrasporangia cruciate, scattered in cortex. Revised description (Clarkston & Saunders 2013: 33).

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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