Description: Thallus erect, attached by a rhizomatose holdfast; monopodial with many polysiphonous cylindrical branches, 5 pericentrals enclosed by several layers of corticating tissue; branches regularly and pectinately arranged in two adaxial rows, often paired, branches dorsiventrally oriented, especially notable in distal branchlets which have recurved apices. Trichoblasts in a single median row on dorsal side of thallus. Reproduction by lanceolate tetrasporangial stichidia formed in positions of ultimate branchlets; tetrasporangia tetrahedrally divided, two per segment forming two longitudinal rows in the stichidia, borne on pericentrals 3 and 4. Gametangia borne in positions of trichoblasts on dorsal sides of specially produced polysiphonous ramuli; spermatangial capitula ovoid, several on each ramulus; cystocarps spheroid to ovoid, usually singly produced on fertile ramuli which become stalks of mature cystocarps.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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