Description: Foliose, entire or lobed, perforate or not, occasionally spinose, usually about as broad as tall. Subsessile or with short stipe. Holdfast discoid. Medulla predominantly filamentous but including many-armed isodiametric cells and stellate cells, which can contain refractive material. Cortex thin; cortical cells isodiametric, progressively smaller toward cuticle. Dioecious, where known. One or more 3-celled carpogonial branches borne on supporting cell with subsidiary cells. After fertilization, carpogonial fusion cell producing gonimoblast filaments that contact auxiliary cells on separate branches. Auxiliary cell ovoid, with 3-8 subspherical to ovoid subsidiary cells. Carposporangia in groups, intermixed with filaments. Cystocarps immersed. Spermatangia superficial. Tetrasporophyte isomorphic. Tetrasporangia small, cruciate, scattered in cortex.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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