Holotype species: Gloeophycus koreanus I.K.Lee & S.A.Yoo

Original publication and holotype designation: Lee, I.K. & Yoo, S.A. (1979). Gloeophycus koreanum gen. et sp. nov. (Rhodophyta, Gloiosiphoniaceae) from Korea. Phycologia 18: 347-354.

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.

Taxonomic notes
According to Saunders et al. (2016), the affinities of the genera Gloeophycus and Peleophycus need consideration as both are atypical members of the Gloeosiphoniaceae in being characterized by terminal auxiliary cells. They are provisionally placed in the Schimmelmanniaceae and Acrothesauraceae respectively. - (3 Oct 2016) - Wendy Guiry

Description: Uniaxial, soft, mucilaginous, branched to four orders, with successively narrower orders of branches. Rhizoids surrounding large, central axial cell and four medially situated periaxial cells, each producing pseudodi- or -trichotomously ramifying determinate, corticating branches of cuneate to ovate cells. Hairs present. Monoecious. Carpogonium borne on an adventitious branch; terminal four cells representing supporting cell and three-celled carpogonial branch. Two-celled branch on supporting cell terminating in the auxiliary cell. Fertilized carpogonium fusing directly or via a connecting cell with auxiliary cell. A single gonimoblast initial producing the gonimoblast, which remains immersed in the thallus with no special development of surrounding tissue. Almost all cells developing into carposporangia. Spermatangia superficial, two or three (-six) cut off by oblique walls. Tetrasporophyte heteromorphic, crustose, producing cruciate tetrasporangia under short-day conditions. Spore germination: diprotocellular type.

Numbers of names and species: There is only one species or infraspecific name in the database at present, which has 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.
