Description: Thallus filamentous, with erect axes arising from a prostrate system. Axes corticated, each axial cell with distal nodes of 6 or more periaxial cells, these producing 3 cortical initials (2 acropetal and 1 basipetal). First acropetal initial bearing 2 or 3 acropetal cells, or 1 or 2 acropetal cells and a vesicular cell or short spinous branch. Second acropetal initial bearing a 1- or 2-celled acropetal filament and a many-celled basipetal filament. Basipetal initial also bearing a many-celled basipetal filament, these longitudinally aligned, covering the axial cell, their cells not or rarely transversely aligned. Spinous branches usually prominent at apices, occasionally dehiscent. Spermatangia in clusters around upper nodes. Cystocarps spherical, 1 or 2 at each fertile node, surrounded by 3 or more short modified involucral branchlets. Tetrasporangia in whorls, with or without involucral 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
