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: Thallus filamentous, ecorticate, erect from a prostrate system; prostrate axes with unicellular rhizoids and erect axes arising at proximal ends of cells; erect axes often forming unilaterally and dividing irregularly to subdichotomously or trichotomously; cells multinucleate; trichoblasts conspicuous at branch apices but deciduous. Spermatangia borne in open dense naked clusters on short lateral branches at articulations. Procarps subapical on short (3-celled) fertile axes; hypogenous (basal) cell becoming large and pyriform; subapical cell bearing a sterile pericentral cell and a supporting cell, the latter with a sterile cell in addition to the 4-celled carpogonial branch. Carposporophytes terminating branchlets; gonimoblasts surrounded by a whorl of involucral cells arising from the hypogenous cell. Tetrasporangia stalked, 4–8 or more in whorls at upper articulations, lacking involucral filaments, tetrahedrally divided.

Numbers of names and species: There are 16 species names in the database at present, as well as 4 infraspecific names. Of the species names, 14 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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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