Original publication and holotype designation: Shepley, E.A. & Womersley, H.B.S. (1983). The Dumontiaceae (Cryptonemiales, Rhodophyta) of southern Australia. Transactions of the Royal Society of South Australia 107: 201-217, 6 figs.
Taxonomic status: currently recognized as a distinct genus.
Gender: This genus name is currently treated as feminine.
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: Upright, soft, multiaxial, subdichotomously branched to eight orders. Branches slightly compressed. Medulla filamentous, with secondary pit connections. Cortex of subdi-, trichotomously branched filaments of elliptical to ovoid cells, some terminating in thick-walled, distally rounded, hyaline hairs. Monoecious. Carpogonium terminating a long, distally recurved, adventitious filament with sterile cells borne proximally. Fertilized carpogonium contacting enlarged cell(s) of carpogonial branch, and fusion product initiating connecting filaments that contact successive intercalary auxiliary cells on a highly branched adventitious filament. Three to four gonimoblast initials produced from remnant of connecting filament attached to auxiliary cell. Most cells of gonimoblast maturing into numerous, small carposporangia. Cystocarp embedded. Spermatangia cut off outer 3-4 layers of cortical cells. Tetrasporophyte unknown. Spore germination: One division within spore wall, then one or both cells producing rhizoid-like filaments that eventually branch.

Comments: Known only from southern Australia and only as an epiphyte of the seagrass Amphibolis.
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.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
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.
