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: Lanceolate, simple or divided, with a terete stipe and discoid holdfast. Midrib distinct, percurrent, with pinnate branches, simple or forked, extending into blade. Medulla filamentous. Cortex of isodiametric cells, progressively smaller toward cuticle. Reproductive structures occurring in papillae on surface of blade. A single 3-celled carpogonial branch borne on each supporting cell together with one or two subsidiary cells. Fusion cell involving supporting cell and subsidiary cells only, producing nonseptate connecting filaments that contact separate auxiliary cells, also bearing subsidiary cells. Groups of carposporangia separated by sterile filaments. Spermatangia undescribed. Tetrasporophyte isomorphic. Tetrasporangia zonate, scattered in cortex.

Comments: Low intertidal in areas exposed to heavy surf. Known only from the northeast Pacific Ocean: eastern Gulf of Alaska to central California.

Numbers of names and species: There are 5 species names in the database at present, of which 5 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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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