Description: Thalli erect, attached by rhizomatous holdfast, up to 3(+) dm high. Many cylindrical branches, polysiphonous with 4 pericentral cells; pigmented, branched trichoblasts on every segment, forming a 1/4 spiral series, often deciduous but sometimes persistent; few to many short, spur- to thorn-like polysiphonous branchlets endogenously formed on axes adjacent to trichoblasts; sometimes indeterminate branches developed instead. Thick proximal cortication but distal regions often thinly corticated. Reproductive structures on trichoblasts. Tetrasporangial stichidia distal in trichoblast, often with monosiphonous trichoblast branchlets along axis; one tetrasporangium per segment forming a spiral series that usually is swollen at maturity. Procarps on 2nd cell from base of trichoblast, becoming polysiphonous; cystocarp ovoid and with a short stalk. Spermatangia formed on regenerated polysiphonous branches, lateral on trichoblasts (Masuda (1982).

Verification of Data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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