Lectotype species: Kallymenia reniformis (Turner) J.Agardh
Original publication:Agardh, J.G. (1842). Algae maris Mediterranei et Adriatici, observationes in diagnosin specierum et dispositionem generum. pp. [i]-x, 1-164. Parisiis [Paris]: Apud Fortin, Masson et Cie.
Type designated in Schmitz, F. (1889). Systematische Übersicht der bisher bekannten Gattungen der Florideen. Flora oder Allgemeine botanische Zeitung 72: 435-456, pl. XXI.
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.
Two species were initially included by Agardh (1842: 99), Kallymenia Requienii and Kallymenia reniformis. Athanasiadis (2016: 649) lists Kallymenia requienii Montagne as the "typ." The genus was however lectotypified by Schmitz (1889: 441) with Kallymenia reniformis. - (24 Jan 2017) - M.D. Guiry
"The genus Kallymenia is greatly reduced in our system. Of the numerous species included in our phylogenetic analyses, it retains only K. ercegovicii, K. feldmannii, K. patens, K. reniformis, and an undescribed species (LLG2684) from the Port-Cros national parc, Marseille, France (Fig. 1, Table S1, doi/10.7872/crya/ v38.iss2.2017.Suppl.Mat.1). These species are all polycarpogonial with the carpogonial complex lacking subsidiary cells, and are nonprocarpic with the auxiliary cell system having associated subsidiary cells. As recognized here, all species are restricted to the Mediterranean Sea except K. reniformis, which is distributed in the northeast Atlantic from Macaronesia to the northern United Kingdom. As such, the genus may be endemic to this region having recently diversified in the Mediterranean Sea. Other regions reported to have species of Kallymenia require further study to test this hypothesis [e.g. the Caribbean Sea (Littler & Littler, 2000), Hawaii (Abbott, 1999)]." (G.W.Saunders et al. 2017: 104). - (28 Jun 2017) - M.D. Guiry
Description: Foliose, entire or lobed, perforate or not, occasionally spinose, usually about as broad as tall. Subsessile or with short stipe. Holdfast discoid. Medulla predominantly filamentous but including many-armed isodiametric cells and stellate cells, which can contain refractive material. Cortex thin; cortical cells isodiametric, progressively smaller toward cuticle. Dioecious, where known. One or more 3-celled carpogonial branches borne on supporting cell with subsidiary cells. After fertilization, carpogonial fusion cell producing gonimoblast filaments that contact auxiliary cells on separate branches. Auxiliary cell ovoid, with 3-8 subspherical to ovoid subsidiary cells. Carposporangia in groups, intermixed with filaments. Cystocarps immersed. Spermatangia superficial. Tetrasporophyte isomorphic. Tetrasporangia small, cruciate, scattered in cortex.

Numbers of names and species: There are 86 species names in the database at present, as well as 15 infraspecific names. Of the species names, 36 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.

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.
