Description: Thallus erect or with prostrate and erect axes; growth by alternate oblique divisions of apical cells. Primary indeterminate axes with 3–5 whorl branches per axial cell; indeterminate branches arising from basal cells of whorl branches; cortication present or absent, formed by encircling filaments arising from reduced or basal cells of regular whorl branches, and (in some species) descending rhizoids arising from basal cells of whorl branches, or (in some species) secondary filaments arising from descending rhizoids. Cells uninucleate. Spermatangia arising in involucrate pedicellate heads borne on the basal cells of whorl branches. Carposporophytes terminal on branches, with a large fusion cell subtending gonimoblasts, with terminal carposporangia; involucral filaments in 2 ranks. Tetrasporangia borne on lower cells of whorl branches, involucrate, 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
