Description: Plant a large, to 50 cm, more or less circular, umbilicate, decumbent to mostly erect blade, with a short, central, discoid holdfast and frequently with numerous, secondary, peg-like haptera; margin undulate, entire or deeply incised to center of blade. Blade cartilaginous and thick, to 640 µm, with filamentous, mesh-like medulla comprising 75% of blade thickness, grading to cellular cortex of subspherical cells. Female gametophytes producing papillae; carpogonial branches and earliest post-fertilization stages not seen; diploidized auxiliary cell forming lateral and inward protusions; gonimoblast cells growing outward and forming terminal, tubular cells that fuse with surrounding vegetative gametophyte cells that have not formed an envelope around the expanding gonimoblast cells; cystocarps borne on papillae on female gametophytes. Tetrasporophytes form tetrasporangia entirely from secondary medullary filaments.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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