Description: Sporophyte composed of a lanceolate blade, flattened stipe and discoidal holdfast; the blade thin, membranous, up to 2 m in length, with obvious thickened rim at the transition zone forming a raised ""V," without undulations, filled with fine, loose filaments including trumpet-shaped hyphae; the stipe rectangular, solid, slightly translucent, reaching 1 m in length; the holdfast semidiscoidal, up to 0.15 m in diameter. No mucilage organs or hairs present. Fertile sporophyte unknown.

Taxonomic status: This name is of an entity that is currently accepted taxonomically.

Most recent taxonomic treatment adopted: Kawai, H., Hanyuda, T., Ridgeway, L.M. & Holser, K. (2013). Ancestral reproductive structure in basal kelp Aureophycus aleuticus. Scientific Reports 3(2491): 1-7.

Comments: Distinguishing features: The species is distinguished from related laminarialean species in having characteristic sporophyte morphology with discoid holdfast and thin blade with V-shaped thickened transition zone, and its distinctive nucleotide sequences of rbcL and ITS rDNA (rbcL rDNA sequence AB355025 and ITS rDNA AB355026). Etymology: Named for the prominent golden-yellow color of the V-shaped rim at the transition zone of the blade and stipe for the generic name, and the geographic distribution of the taxon for the species epithet. The species has been given the common name Golden V kelp by those who have seen it inthe field.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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