Type designated in: Fott, B. (1974). Taxonomie der palmelloiden Chlorococcales (Familie Palmogloeaceae). Preslia 46: 1-31.

Description: Thalli 2-8 to many celled spherical to irregular shaped colonies to 100 &;m in diameter. Mucilage structureless with distinct cell wall remnants. Cells spherical with smooth cell walls. Cells uninucleate; chloroplast morphology highly variable, always parietal and single but with compact, cup-shaped, lobed or stellate forms; pyrenoid single. Asexual reproduction by autospores produced 2-4-8 within sporangia and released by rupture or splitting of cell wall into two to several portions. Flagellated stages and sexual reproduction unknown. Coenochloris usually planktonic. Most species reported only from Europe, with one species, C. mucolamellata from Cuba; two other possible species from Antarctica (as Sphaerocystis). There is some taxonomic confusion between Coenochloris and Sphaerocystis. Coenochloris distinguished from Coenococcus and Coenocystis by the presence of cell wall remnants after autospore formation. With the description of Korschpalmella and Neocystis, generic concept of Coenochloris considerably restricted compared to Komárek &; Fott (1983).

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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