Taxonomic notes
Neustupa et al. (2011: fig. 22) place in the Prasiola-clade (Trebouxiophyceae). - (18 Mar 2011) - Wendy Guiry

Description: Plants consisting of globular cells, often forming sarcinoid packets by division in three planes, occasionally as short, uniseriate, filaments. Cells uninucleate, each with single, parietal chloroplast and pyrenoid. Asexual reproduction by aplanospores produced in large, spherical sporangia with a verrucose or punctate surface. Sexual reproduction unknown. Desmococcus cosmopolitan on soil-free subaerial surfaces including walls and bark of trees especially in both shaded and polluted habitats where lichens are uncommon. Probably the most common alga forming the so-called "proto-pleurococcoid" assemblage. In the past considerable taxonomic confusion has surrounded this genus and others closely related to it (e.g. Apatococcus, Chlorococcum, Pleurococcus, Protococcus).

Numbers of names and species: There are 7 species names in the database at present, of which 3 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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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