Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Womersley, H.B.S. (1994). The marine benthic flora of southern Australia - Part IIIA - Bangiophyceae and Florideophyceae (Acrochaetiales, Nemaliales, Gelidiales, Hildenbrandiales and Gigartinales sensu lato). pp. 1-508, 167 figs, 4 pls, 4 maps. Canberra: Australian Biological Resources Study.

Description: Plants reach 30 cm in length and are erect from a crustose holdfast, the fronds being flat, irregularly furcate, gelatinous to firm in texture and relatively thick. Each cell of the axial filament bears two periaxial derivatives, although central filaments are obscured by the considerable development of medullary filaments and rhizoids. The cortex is pseudoparenchymatous, the surface layers forming only weakly defined rosettes. Gonimoblast development is typical of the family. Cystocarps have several small cells or, at times, one more or less conspicuous cell, at the center, the central sterile mass surrounded by elongate gonimoblast filaments bearing chains or clusters of carposporangia interspersed with a few sterile filaments running to the pericarp. Although generally similar to Rhodophyllis, it is maintained by Min-Thein and Womersley (1976) because of its abrupt medulla to cortex transition and the composition of the carposporophyte, in which either a central cluster of sterile cells or an enlarged cell not the result of fusions may be present. The development of small groups, rather than strict chains, of carposporangia, is also distinctive.

Numbers of names and species: There are 2 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
