Description: Foliose, lanceolate, cleft or uncleft, sometimes proliferous from margin, with short, narrow stipe and small discoid holdfast. Thallus surface corrugated. Medulla filamentous. Inner cortical cells stellate to elliptical, branching subdichotomously and becoming progressively smaller and fusiform toward cuticle, inner and intermediate cortical cells forming lateral protuberances. Rhizoids and secondary pit connections present. Ampullae with two orders of branches. Carpogonial branch 2-celled, on primary ampullar filament. Hypogynous cell with sterile lateral. Auxiliary cell a proximal cell of a primary filament or the basal cell of a secondary filament in a separate ampulla. A single, outwardly directed gonimoblast initial producing numerous gonimoblast filaments. Pericarp produced by ampullar filaments. Most gonimoblast cells maturing into carposporangia. Small auxiliary fusion cell and carpostome present. Cystocarp embedded. Spermatangia undescribed. Tetrasporophyte isomorphic. Tetrasporangia small, cruciate, attached subbasally in intermediate cortical layer. Revised description (Rodríguez-Prieto et al., 2022: [15].

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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