Taxonomic status: currently recognized as a distinct genus.

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, radially branched to three orders. Branches tapered at both ends. Axial cell increasing greatly in length, moderately in diameter, surrounded by four periaxial cells, which also elongate and branch di- or trichotomously. Rhizoids present. Cortical cells ovoid to spherical, progressively smaller toward surface. Carpogonium terminating a moderately long, distally recurved, adventitious filament. Fertilized carpogonium contacting enlarged cell(s) of carpogonial branch, and fusion product initiating connecting filaments that contact auxiliary cells on separate adventitious filaments. Up to four gonimoblast initials developing from remnant of connecting filament attached to auxiliary cell. Most cells of gonimoblast maturing into carposporangia. Auxiliary fusion cell formed. Spermatangia superficial. Tetrasporophyte isomorphic. Tetrasporangia zonate, attached basally, scattered in cortex.

Numbers of names and species: There are 3 species names in the database at present, of which 1 has 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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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