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: Member of the Kallymeniaceae with foliose blades; medulla lax, with an interconnected network of slender filaments and stellate cells; inner cortex typically one or two layers of periclinally elongated cells internal to two or three layers of smaller cortical cells that decrease in size towards the surface. Nonprocarpic; supporting cells either mono- or polycarpogonial, also carrying up to ten subsidiary cells; supporting cell, carpogonial branch cells and subsidiary cells typically elongate to some degree. Fusion cells, where known, prominent, deeply lobed, incorporating the supporting and subsidiary cells and issuing long connecting filaments. Auxiliary cell systems formed by the auxiliary cell bearing up to six subsidiary cells. Gonimoblast filaments develop from the auxiliary cell or from the connecting filament near the site of fusion with the auxiliary cell.

Numbers of names and species: There are 25 species names in the database at present, as well as 1 infraspecific names. Of the species names, 3 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
