Description: thalli monoecious; blue-greenish, consistency mucilaginous; branching irregular; whorls well developed, contiguous, barrel-shaped or spherical; cortication of the main thallus axis well developed with filaments of cylindrical cells; primary fascicles straight, formed by cylindrical, ellipsoidal, obovoidal, or subspherical cells; secondary fascicles abundant and covering the entire internode; spermatangia spherical or obovoidal, terminal or sub-terminal on primary or secondary fascicles; carpogonial branches well differentiated from the fascicles, straight, short, developing from the periaxial of primary fascicles, composed of disc- or barrel-shaped cells; involucral filaments composed of 1–3 ellipsoidal or fusiform proximal cells and usually 1–2 clavate upper distal cells forming a rosette around the carpogonia; carpogonia with sessile, clavate or obovoidal trichogynes; fertilized carpogonia and subtending cells of carpogonial branches with enlarged pit connections (>3 µm wide); fertilized carpogonia germinate to directly form the filaments of the Chantransia-stage which grow on the old gametophyte; initial filaments arising coiled around the fertilized carpogonium and later forming upright filaments; carposporophytes one-celled, consisting of the fertilized carpogonia.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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