Holotype species: Wrightiella blodgettii (Harvey) F.Schmitz
Original publication and holotype designation: Schmitz, F. (1893). Die Gattung Lophothalia J. Ag. Berichte der deutsche botanischen Gesellschaft 11: 212-232.
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: Thalli erect, attached by rhizomatous holdfast, up to 3(+) dm high. Many cylindrical branches, polysiphonous with 4 pericentral cells; pigmented, branched trichoblasts on every segment, forming a 1/4 spiral series, often deciduous but sometimes persistent; few to many short, spur- to thorn-like polysiphonous branchlets endogenously formed on axes adjacent to trichoblasts; sometimes indeterminate branches developed instead. Thick proximal cortication but distal regions often thinly corticated. Reproductive structures on trichoblasts. Tetrasporangial stichidia distal in trichoblast, often with monosiphonous trichoblast branchlets along axis; one tetrasporangium per segment forming a spiral series that usually is swollen at maturity. Procarps on 2nd cell from base of trichoblast, becoming polysiphonous; cystocarp ovoid and with a short stalk. Spermatangia formed on regenerated polysiphonous branches, lateral on trichoblasts (Masuda (1982).

Numbers of names and species: There are 3 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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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