Description: Highly branched cylindrical thalli, up to 15 cm tall, with more or less proximally constricted, claviform branches, usually verticillately branched. Distal ends of branches broadly rounded to truncate, apical cell and trichoblasts in center and slightly protruding or sunken in a shallow pit. Five pericentral cells, each an inverted L-shape, the distal arm long and terminating in connections to short corticating filaments that unite with those adjacent to enclose a vesiculate thallus segment or branch. Tetrasporangia borne in distal branches, embedded in the cortex. Cystocarps spheroidal to urceolate, protruding on the surface of ultimate thallus segments. Male capitula (Gordon-Mills and Womersley 1987) flattened plate-like structures with vein-like sterile cells and sterile marginal cells.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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