Taxonomic status: currently regarded as a synonym of Erythrophyllum.

Gender: This genus name is currently treated as feminine.

Most recent taxonomic treatment adopted: Mikhaylova, T.A. & Sokolova, I.V. (2020). Type and authentic specimens in algal herbarium of the Komarov Biotanical Institute (LE). II. Botanicheskii Zhurnal (St. Petersburg) 105: 1114-1126, no figs.

Nomenclatural notes
According to Mikhaylova & Sokolova (2020: 1125), "The genus name Kallymeniopsis Perest. was published by Perestenko (1975: 1679) with a Latin description, but without type indication as required by Art. 40.1 of the ICN (Turland et al., 2018), so it was not validly published. Later, Perestenko attempted to validate the genus name by indicating K. lacera (Postels et Rupr.) Perest. as its type (Perestenko, 1977: 398); she did not, however, provide it with a full and direct reference to the validating description (Turland et al., 2018: Art. 33.1, 41.5 Note 1), so the validation was not achieved. Since the genus name was not validated at the time of publication of the species name K. verrucosa (Zinova, Gussarova, 1977), the latter was not validly published either (Turland et al., 2018: Art. 35.1). The genus name was indeliberately validated later (Norris, 2014: 344)." - (12 May 2007) - Wendy Guiry

Taxonomic notes
Kallymeniopsis is a likely synonym of Erythrophyllum, but the generitype has not been sequenced (Schneider & Wynne 2019). - (27 May 2019) - M.D. Guiry

Description: Foliose, orbiculate, reniform or circinnate, entire or dissected into wedge-shaped sectors. Margin and surface of blade smooth, undulate or verrucose. Usually stipitate. Holdfast discoid. Medulla filamentous. Cortical cells isodiametric, progressively smaller toward cuticle. A single 3-celled carpogonial branch borne on supporting cell together with up to four subsidiary cells. After fertilization, fusion cell formed, involving only supporting and subsidiary cells. Auxiliary cell borne on separate branch. Filaments interspersed among groups of carposporangia. Cystocarp immersed to protruding. Spermatangia undescribed. Tetrasporophyte isomorphic. Tetrasporangia cruciate, scattered in cortex.

Information kindly contributed by S.C. Lindstrom but may now be outdated.

Comments: Usually subtidal. Known only from the North Pacific: Alaska to the Kurile Islands, U.S.S.R., and the Okhotsk Sea. This genus may fit within Kallymenia.

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

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.
