Holotype species: Oonephris obesa (West & G.S.West) Fott
Original publication and holotype designation:Fott. B. (1964). Oonephris, a new genus of coccoid green algae. Acta Univ. Carol. Biol. 1964 : 129-137.
Taxonomic status: currently recognized as a distinct genus.
Description: Cells solitary or in 2-4-8-(several)-celled colonies within the expanded mother cell wall, often with remnants of mother cell walls of previous generations. Cells ellipsoid, oval, or slightly reniform, 11-58 x 7-48 &m. Cell wall thick, sometimes stratified, smooth, with or without polar thickenings. Chloroplast of young cells stellate, with a central pyrenoid, later becoming reticulate and sometimes with more than one pyrenoid. Asexual reproduction by formation of 2-4-8-(16) autospores which may be temporarily retained within the mother cell walls. Sexual reproduction and flagellated stages unknown. Oonephris, benthic, periphytic, probably cosmopolitan.

Numbers of names and species: There is only one species or infraspecific name in the database at present, which has been flagged as currently accepted taxonomically.
Names: ('C' indicates a name that is currently 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.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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