According to Friedl (1996: 466), the original description of Protoderma is incomplete and no cultures for the type species, Protoderma viride Kützing 1843 exist. - (26 Mar 2012) - Wendy Guiry
Description: A prostrate, attached alga forming a one-layered pseudoparenchymatous thallus composed of a central group of polygonal, irregularly arranged cells from which short, branching filaments extend in all directions. Young stages consist of unbranched or branched irregular filaments. Cells possess one parietal chloroplast with or without a pyrenoid. Asexual reproduction by biflagellate zoospores and by autospores. Cell walls may frequently gelatinize and palmella stages may also be formed. Sexual reproduction by isogamy.

Numbers of names and species: There are 13 species names in the database at present, as well as 2 infraspecific names. Of the species names, 9 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
