Description: Plants form small non-calacified crusts on Laminaria coriacea and consist of loosely aggregated erect filaments bound in a mucilaginous matrix, the filaments arising from a hypothallial layer lacking rhizoids. Only tetrasporangial and spermatangial plants are known in the field, the cruciate tetrasporangia forming terminally on the erect filaments.

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

Most recent taxonomic treatment adopted: Saunders, G.W., Jackson, C. & Salomaki, E.D. (2017 '2018'). Phylogenetic analyses of transcriptome data resolve familial assignments for genera of the red-algal Acrochaetiales-Palmariales complex (Nemaliophycidae). Molecular Phylogenetics and Evolution 119: 151-159, 2 fig., 3 tables.

Comments: As in the case of Pseudorhodiscus, the affinities of Rhodophysemopsis appear to lie with the Palmariales. Distribution: The type species is endemic to Hokkaido, northern Japan. A second species, R. hyperborea (Rosenvinge) Masuda, occurs in Greenland.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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