Dermocorynus P.& H. , 1858
Holotype species: Dermocorynus montagnei P.Crouan & H.Crouan
Original publication and holotype designation: Crouan, P.L. & Crouan, H.M. (1858). Note sur quelques algues marines nouvelles de la rade de Brest. Annales des Sciences Naturelles, Botanique, Quatrième série 9: 69-75, pl. 3.
Taxonomic status: currently recognized as a distinct genus.
Gender: This genus name is currently treated as masculine.
According to Athansiadis (1996: 634), "After the neuter substantive Greek word derma (skin) and the feminine substantive Greek word clava (De Toni 1905: 1586). Hence the correct orthography should be Dermocoryne (cf. Microcoryne Strömfelt and Polycoryne Skottsberg)." A change ir orthography and gender from Dermocorynus to Dermocoryne (see Athanasiadis 2016: 646, note 3), if warranted, should be made by formally proposing conservation of the changed orthography. - (18 Jan 2017) - M.D. Guiry
Placed in synonymy with Grateloupia by Wilkes et al. (2005: 58). Schneider & Wynne (2013: 115) note that Gargiulo et al. (2013) resurrected Dermocoryus from synonymy with Grateloupia using reproductive and molecular data. - (8 Aug 2006) - Wendy Guiry
Description: Horizontally expanded crust of mostly unbranched filaments of nearly isodiametric cells. Outer covering mucilaginous. Rhizoids and secondary pit connections lacking. Hairs apparently absent. Monoecious. Reproductive structures in minute erect, simple or bifurcate, cylindrical to compressed papillae with a filamentous medulla of elongate and stellate cells and a cortex of inner stellate cells and elliptical cells only slightly smaller toward cuticle. Secondary pit connections present. Ampullae with one to four orders of branches. Carpogonial branch 2-celled, on primary ampullar filament; hypogynous cell with sterile lateral. Auxiliary cell intercalary in primary or basal in secondary filament, in separate ampulla. Fertilized carpogonium and hypogynous cell issuing connecting filaments. Single outwardly directed gonimoblast initial cut off auxiliary cell after contact by connecting filament, producing numerous gonimoblast filaments. Auxiliary fusion cell formed. Pericarp developing from auxiliary cell. Carpostome present or absent. Spermatangia cut off by oblique walls. Tetrasporophyte isomorphic. Tetrasporangia small to medium, cruciate or irregular, attached subbasally in intermediate cortical layer, occurring in a slightly protruding, gelatinous sorus in type species. Spore germination: protuberance leaving behind empty spore, developing into disc.

Numbers of names and species: There are 4 species names in the database at present, of which 4 have 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.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
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.
