Most recent taxonomic treatment adopted: Huisman, J.M. (2018). Algae of Australia. Marine benthic algae of north-western Australia. 2. Red algae. pp. [i]-xii, 1-672, 189 figs. Canberra & Melbourne: ABRS & CSIRO Publishing.

Description: Thallus prostrate. Structure multiaxial, with a filamentous medulla and a cortex of narrow anticlinal widely separated pseudodichotomous filaments, the intervening inner-cortical spaces filled with longitudinally running rhizoids and rhizines; secondary pit connections present in the inner cortex. Gametophytes monoecious, dioecious or possibly protandrous. Spermatangia forming in broad subterminal and submarginal sori. Carpogonial branches straight, 3- or 4-celled, borne singly on undifferentiated inner-cortical supporting cells. Auxiliary cells and early gonimoblast stages unknown. Mature cystocarps thick-walled, ostiolate, hollow; carposporophytes lining inner surfaces of the cystocarp cavity; gonimoblast filaments growing centripetally, producing solitary terminal carposporangia. Tetrasporophytes unknown.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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