Dermatophyton A.Peter, 1886: 191
Holotype species: Dermatophyton radians A.Peter
Taxonomic status: currently recognized as a distinct genus.
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.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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