Description: Plants form small, uncalcified crusts anchored apparently without rhizoids and consisting of one to several layers of radiating prostrate filaments. Erect filaments occur only in conjunction with tetrasporangial sori, the tetrasporangia being borne in terminal or intercalary chains. Gametophytes are unknown.

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

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.

Comments: Dixon and Irvine (1977) have placed this problematic genus in the Phyllophoraceae because of the catenate tetrasporangia. The independent status of Erythrodermis is doubtful, especially with the studies of DeCew and West (1981) and Masuda (1987) showing that Gymnogongrus species in California and Japan produce Erythrodermis-like tetrasporophytes. Distribution: The type species is apparently restricted to subtidal hard substrata in southern England. A second species, E. Pacifica Hollenberg, grows subtidally in the Puget Sound of western North America.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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