Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: 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.

Description: Thallus shortly stipitate or sessile with lobed or rounded blades with age becoming divided and laciniate. Structure multiaxial, composed of a mostly filamentous medulla; cortex composed of three to five layers of isodiametric cells in size decreasing towards the surface; stellate cells forming a compact subcortical layer. Dioecious; polycarpogonial three-celled carpogonial branches borne on supporting cell, which also produces four to six subsidiary cells. Fusion cells and connecting filaments are present, auxiliary cells not identified. Gonimoblasts arising from vegetative cells. Carposporangia formed in groups, intermixed with filaments. Carposporophytes immersed in young thalli, in mature thalli progressively more protuberant. Spermatangia in superficial sori on both sides of the lamina. Tetrasporangia not found in thalli bearing blades. Carpospores germinate to produce crustose thalli.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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