Taxonomic status: currently recognized as a distinct genus.
Gender: This genus name is currently treated as feminine.
Most recent taxonomic treatment adopted: Schneider, C.W. & Wynne, M.J. (2007). A synoptic review of the classification of red algal genera a half a century after Kylin's "Die Gattungen der Rhodophyceen". Botanica Marina 50: 197-249.
Description: Uniaxial, firm, subcylindrical to distinctly flattened and ligulate. Subdichotomously branched to eight orders. Obscurely to distinctly costate. Rhizoids surrounding axial and four distally situated periaxial cells. Cortex of subspherical to elliptical cells, decreasing in diameter toward surface of thallus. Cuticle present. Dioecious. Carpogonium terminating a long, proximally branched, distally recurved, adventitious filament with distally enlarged cells. Auxiliary cell intercalary, distal, among enlarged cells, on a separate, adventitious, percurrent filament. Gonimoblast developing from remnant of connecting filament, which can initiate additional connecting filaments, attached to auxiliary cell. Only distal cells of gonimoblast maturing into carposporangia; proximal cells incorporated into a gonimoblast fusion cell. Carposporangia small, released through a carpostome. Spermatangia superficial, cut off by oblique walls. Tetrasporophyte isomorphic. Tetrasporangia small, irregularly cruciate to irregularly zonate, attached basally.

Numbers of names and species: There are 4 species names in the database at present, of which 2 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..
Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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