Request PDFDescription: Thallus cartilagineous, lanceolate-complanate, 15-20 cm high, attached to the substratum by a discoid holfast. Erect axes cylindrical at the base, soon flattened, up to 1 cm broad, ending in lanceolate or truncate apices. Primary and secondary branches arising from the margins of the main axes and similar in appearance to the main axes; narrowed and nearly cylindrical at the base, expanded and compressed distally. Axes and branches with a notorious mid-rib and with margins invested with numerous leaf-like proliferations. In cross section the cortical cells are rounded, 4-8 µm diam., gradually grading into larger cortical cells and then into modullary cells, 8-20 µm diam. Elongated, colourless cells (named rhizines, hyphae or rhizoidal filaments) are abundant in the medulla. Cystocarps sphaerical, borne on marginal proliferations in the fertile thalli. Tetrasporangial sori also develop in the marginal proliferations of the thallus.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
