Description: Thallus filamentous, corticated or not, erect or with prostrate and erect axes. Axial cells each with 2 opposite distichous whorl branches, one remaining determinate, the other longer and potentially indeterminate; long whorl branches borne either regularly on every second axial cell or irregularly at intervals of 2–5 cells; corticating filaments arising from basal cells of lateral branches. Vesicular cells spherical, abaxial and/or adaxial, on the lowest cell of whorl branches, occasionally on more distal cells. Spermatangia in dense rounded to cylindrical heads borne adaxially on cells of lateral branches. Carpogonial branches 4-celled, abaxial on basal cells of whorl branches, curving around the supporting cell. Auxiliary cell arising from the adaxial surface of the supporting cell. Carposporophytes developing from auxiliary cell, with 4–6 generally spherical gonimolobes composed entirely of carposporangia. Tetrasporangia solitary or clustered on basal cells of lateral branches, or on short branches arising from them, cruciately divided.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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