Setoutiphycus H.Kawai & T.Hanyuda, 2021
Holotype species: Setoutiphycus delamareoides H.Kawai & T.Hanyuda
Original publication and holotype designation: Kawai, H. & Hanyuda, T. (2021). Discovery of a novel brown algal genus and species Setoutiphycus delamareoides (Phaeophyceae, Ectocarpales) from the Seto Inland Sea, Japan. Scientific Reports 11(13901): 1-11.
Request PDFDescription: Erect thalli, filiform, rarely branched, attenuated towards the base, blunt at the tip, nubby-surfaced, parenchymatous, solid when young and becoming hollow with age, composed of large colorless inner cells, cylindrical cortical cells, and phaeophycean hairs. Plurilocular and unilocular zoidangia formed on the same thallus at the end of subcortical cells among the large cortical cells. Plurilocular zoidangia conical to lanceolate, often with protruding locules at the distal end. Unilocular zoidangia ovate. Each cell containing many discoidal chloroplasts with projected pyrenoids.
Information contributed by: Original description.. The most recent alteration to this page was made on 2021-10-21 by M.D. Guiry.
Taxonomic status: This name is of an entity that is currently accepted taxonomically.
Gender: This genus name is currently treated as masculine.
Comments: The new genus resembles Delamarea in gross morphology and anatomy, but differs in the longer, rarely branched thallus and shorter cortical cells. The species differs from Cladothele in the epilithic habit and rare branching, and from Trachynema in having large cortical cells. Nucleotide sequences of mitochondrial cox1 and cox3, chloroplast atpB, psbA and rbcL genes are also distinctive.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
