Original publication and holotype designation: Saunders, G.W., Huisman, J.M., Vergés, A., Kraft, G.T. & Le Gall, L. (2017). Phylogenetic analyses support recognition of ten new genera, ten new species and 16 new combinations in the family Kallymeniaceae (Gigartinales, Rhodophyta). Cryptogamie Algologie 38(2): 79-132, 126 figs.
Taxonomic status: currently recognized as a distinct genus.
Gender: This genus name is currently treated as feminine.
Most recent taxonomic treatment adopted: Huisman, J.M. & Saunders, G.W. (2018). Kallymeniaceae. In: Algae of Australia. Marine benthic algae of north-western Australia. 2. Red algae. (Huisman, J.M. Eds), pp. 184-191. Canberra & Melbourne: ABRS & CSIRO Publishing.
Description: Thallus with solid or obligately perforate membranous blades, the medulla primarily of sparse filaments and lightly staining stellate cells with irregularly radiating arms. Spermatangia cut off from outer cortical cells. Supporting cell systems mono- or polycarpogonial, bearing up to 4 carpogonial branches and 3–5 subsidiary cells. Fusion cell prominent, incorporating the supporting and subsidiary cells, producing numerous connecting filaments. Auxiliary cell systems with an auxiliary cell and 3–6 (–10) spherical subsidiary cells. Following fusion with a connecting filament, the auxiliary cell produces numerous gonimoblast filaments ultimately cutting off carposporangia. Cystocarps within the medulla, consisting of a dense mass of intermixed filaments and spherical to ovoid carposporangia. Tetrasporangia scattered in the outer cortex, cruciately divided.

Numbers of names and species: There are 3 species names in the database at present, of which 3 have 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.
