Subkingdom Biliphyta
Phylum Rhodophyta
Subphylum Eurhodophytina
Class Florideophyceae
Subclass Rhodymeniophycidae

Holotype species: Thamnophyllis pocockiae R.E.Norris

Original publication and holotype designation: Norris, R.E. (1964). The morphology and taxonomy of South African Kallymeniaceae. Botanica Marina 7: 90-129, 50 figs, 1 table, 10 plates.

Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Saunders, G.W., Huisman, J.M., Verg├ęs, 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: Flabellately to palmately branched to several orders; margins often with proliferations. Membranous or coriaceous. Stipe short or absent. Holdfast small, discoid. Medulla of isodiametric to irregularly elliptical cells, some becoming stellate. Cortex of isodiametric cells, progressively smaller toward cuticle. Chains of small cells developing from inner cortex and growing into medulla. A central layer of periclinal filaments evident in older parts of thallus. Dioecious, where known. Up to twelve 3-celled carpogonial branches borne on supporting cell. First cells of carpogonial branches usually elongate and sometimes lobed. After fertilization, fusion cell formed by supporting cell and first cells of carpogonial branches, producing nonseptate connecting filaments that contact separate auxiliary cells, which bear up to ten subsidiary cells. Gonimoblast developing from the connecting filament in contact with auxiliary cell. Cystocarps immersed but causing localized swelling of thallus. Clumps of carposporangia separated by filaments of both medullary and gonimoblast origin. Spermatangia superficial. Tetrasporophyte isomorphic. Tetrasporangia small, cruciate or irregular, scattered in cortex.

Numbers of names and species: There are 4 species names in the database at present, of which 2 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.
