Axial cells with whorls of 4-6 determinate branchlets each bearing 2-4 upwardly-curved filaments from the basal cell. Dense rhizoidal cortication with outer ends of curved filaments projecting to form a soft pilose outer layer. Carpogonial branches 4-celled borne on basal cells of determinate branchlets near branch apices and auxiliary cell, formed from supporting cell, giving rise to carposporophyte with rounded groups of carposporangia each with elongate stalk cell. Pit-connection formed between lower auxiliary cell and fertile axial cell. Spermatangia on short branches on filaments of determinate branchlets. Tetrasporangia terminal on outer branches of filaments, tetrahedrally-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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
