Description: Plants are erect and filiform, the terete branches being irregularly produced. The axial filament is not distinguishable in cross-section, which is pseudoparenchymtous and densely compact throughout. Surface cortical cells form rosettes around larger subsurface cells in a manner typical of the Cystocloniaceae. Prominently protruding cystocarps are scattered over the upper thallus and consist of a basal small celled tissue bearing branched gonimoblasts of mostly carposporangia. Spermatangia and tetrasporangia are unknown.

Taxonomic status: This name is of an entity that is currently accepted taxonomically.

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.

Comments: Distribution: This species is apparently known only from the Port Phillip Heads (southeastern Australia) type collection. Min-Thein and Womersley (1976) consider it a probably valid genus, but too little material was available for definitive study.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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