Holotype species: Austroclonium charoides (Harvey) Min-Thein & Womersley

Original publication and holotype designation: Min-Thein, U. & Womersley, H.B.S. (1976). Studies on southern Australian taxa of Solieriaceae, Rhabdoniaceae and Rhodophyllidaceae (Rhodophyta). Australian Journal of Botany 24: 1-166, 69 figs.

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 15 cm in length, are erect from a discoid holdfast, and are segmented and subverticillately branched. The medulla is broad and contains a prominent axial filament (each cell of which bears 2 periaxial cells) and rhizoidal filaments. The cortex is thin, only 1-2 layered, with large inner cells and small surface cells that form rosettes. Gametophytes are dioecious. Fusion cells are lateral to the central axial filament. Cystocarps are ostiolate, the pericarps surrounding the gonimoblast with an inner loose filamentous sheath, and swell the branches.

Comments: Distribution: Endemic to southern Australia, where it grows subtidally.

Numbers of names and species: There is only one species or infraspecific name in the database at present, which 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
