Holotype species: Glaphyrymeniopsis mollis Kraft & G.W.Saunders
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: Schneider, C.W. & Wynne, M.J. (2019). Fourth addendum to the synoptic review of red algal genera. Botanica Marina 00: [1-13].
Description: Member of the Kallymeniaceae with orbicular, [f]oliose blades; medulla uniform throughout, loosely filamentous, cells narrow or centrally inflated and stellate but not ganglioid; cortex shallow, 1-3-layered, the cells arising directly from medullary filaments. Nonprocarpic; supporting cells borne on peripheral medullary filaments, directed inwardly, bearing a single spherical subsidiary cell and a threecelled carpogonial branch, the basal cell being the same shape and size as the subsidiary cell, the hypogynous cell spherical but smaller, the carpogonium conical, inwardly directed with a reflexed trichogyne. Presumed fertilization followed by formation of a lateral projection of the supporting cell from which several septate connecting filaments arise; fusion cells lacking. Auxiliary-cell complex similar to that of the supporting cell, the auxiliary cell bearing two subsidiary cells, one occasionally dividing into two cells. Gonimoblast initial clavate, arising on the incoming connecting filament near but not at its point of fusion to the auxiliary cell, the connecting filament then growing on to effect further diploidizations. Fusion cell not formed; gonimoblast initials multiple, carposporangial filaments radiating from a central mass of sterile gonimoblasts, forming peripheral clusters of carposporangia unmixed with vegetative tissue; carposporophytes at maturity globular, composed of a confluent mass of carposporangia. Tetrasporangia scattered, ovoid, decussatecruciate, terminal on cortical mother cells.
Origin of description: this description is from the original publication; it may have been modified slightly.
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.

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.
