Holotype species: Thuretellopsis peggiana Kylin

Original publication and holotype designation: Kylin, H. (1925). The marine red algae in the vicinity of of the Biological Station at Friday Harbor, Wash. Lunds Universitets Årsskrift, Ny Följd, Andra Afdelningen 21(9): 1-87, 47 figs.

Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Schneider, C.W. & Wynne, M.J. (2007). A synoptic review of the classification of red algal genera a half a century after Kylin's "Die Gattungen der Rhodophyceen". Botanica Marina 50: 197-249.

Description: Uniaxial, terete, mucilaginous, irregularly branched to two orders. Central axial filament of large cells, each bearing dense, subdichotomously branched cortical fascicles. Rhizoids from inner cortical cells cloaking axis. Hairs present. Cuticle and secondary pit connections lacking. Monoecious. Carpogonium terminating a distally recurved, proximally branched, adventitious filament. Fertilized carpogonium dividing, each product fusing with a cell of the carpogonial branch, then producing connecting filaments that contact a succession of usually proximal auxiliary cells on separate, proximally branched, adventitious filaments. Cystocarp embedded in thallus; most if not all cells maturing into relatively small carposporangia. Spermatangia distal on distal cells of cortical fascicles, cut off by oblique walls. Tetrasporophyte heteromorphic, crustose. Tetrasporangia cruciate.

Numbers of names and species: There are 2 species names in the database at present, of which 1 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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
