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: Erect, cartilaginous, cylindrical thalli with a discoid or rhizomatous holdfast, up to 20 cm tall. Polysiphonous with 4 pericentral cells, thickly corticated with pseudoparenchyma forming large-celled medulla and small-celled cortex. Polysiphonous branches replacing trichoblasts, both exogenous, spirally arranged on axis in 1/4 divergence. Trichoblasts branched, colorless and soon deciduous. Endogenously developed polysiphonous branches often present. Reproductive structures in special, usually determinate branchlets. Tetrasporangia in lanceolate branchlets, 1 per segment in a spiral series. Cystocarps lateral on short spine-like branchlets, proximal on larger branches. Male capitula replacing trichoblasts or on lower branch of trichoblast on lateral branches.

Information contributed by: R.E. Norris. The most recent alteration to this page was made on 7 Oct 2010 by M.D. Guiry.

Comments: Subantarctic islands and cold temperate coasts of New Zealand and Australia. The only characters that separate Lophurella from Polysiphonia are the strongly corticated thalli and more specialized tetrasporangial branchlets in Lophurella.

Numbers of names and species: There are 11 species names in the database at present, of which 11 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
