Holotype species: Dermatophyton radians A.Peter

Original publication and holotype designation: Peter, [A.] (1886). Ueber eine auf Thieren schmarotzende Alge. Tageblatt. Versammlung Deutscher Naturforscher und Aerzte in Berlin 59: 191 [with Diskussion on p. 191-193].

Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Boedeker, C., O'Kelly, C.J., Star, W. & Leliaert, F. (2012). Molecular phylogeny and taxonomy of the Aegagropila clade (Cladophorales, Ulvophyceae), including the description of Aegagropilopsis gen. nov. and Pseudocladophora gen. nov. Journal of Phycology 48(3): 808-825.

Description: Plants disc-like, consist of radiating rows of cells. Cells in polystromatic centre quadrate or subquadrate and towards periphery cells more elongated and dichotomously divided. Cells with 6-17 nuclei, a parietal chloroplast and one to several pyrenoids. Asexual reproduction by biflagellate zoospores produced in flask-shaped cells in centre of thallus. Sexual reproduction unknown. Forms deep-green crusts ca. 2-4 mm in diameter on and penetrating carapace of freshwater turtles. Known from southern Europe, North Africa and North America. Dermatophyton questionably placed in Chaetophorales due to presence of many nuclei in each cell. It may be related to Arnoldiella which belongs to the Cladophorales.

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

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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