Chloromonas Gobi, 1899-1900, nom. cons.
Holotype species: Chloromonas reticulata (Goroschankin) Gobi
Original publication and holotype designation: Gobi, C. (1899-1900). Über einen neuen parasitischen Pilz, Rhizidiomyces ichneumon nov. sp., und seinen Nährungsorganismus Chloromonas globulosa (Perty). Scripta Botanica Horti Universitatis Imperialis Petropolitani 15: 251-272.
Description: Unicellular thalli spherical, ovoid, cylindrical or spindle-shaped. Some species exhibit asymmetry of cell shape. Two isokont, anterior flagella. Single, large chloroplast ranges from cup-shaped to laminate. Chloroplast often lobed or perforate (C. perforata). Pyrenoids absent. Papillum absent or present depending on the species. Eyespot prominent in most species (rarely absent), at cell anterior embedded in chloroplast. Nucleus single and typically central. First division longitudinal, sometimes preceded by rotation (depending on the species). Asexual reproduction by zoosporogenesis. Two to four zoospores produced. Palmella and akinete stages have been reported. Sexual reproduction isogamous, anisogamous, or oogamous. Quadriflagellate planozygotes may remain motile for long periods prior to the formation of the zygote wall. Zygote germinates to produce 4 or 8 zoospores. Diagnosis emended by Pröschold et al. (2001: 285). Emend. Wille (Hoham et al. 2002).

Taxonomic status: This name is of an entity that is currently accepted taxonomically.
Most recent taxonomic treatment adopted: Masjuk, N.P., Lilitska, G.G. & Kapustin, D.O. (2011). Chlamydomonadales. In: Algae of Ukraine: diversity, nomenclature, taxonomy, ecology and geography.

Comments: Chloromonas widespread in freshwater. Habitats include soil, temporary pools and eutrophic lakes. Cell wall in zoospores of Chloromonas (published as Chlamydomonas) rosae of the type II lattice similar to Brachiomonas, Chlorogonium, Polytoma, Carteria and some species of Chlamydomonas. The lack of pyrenoids in Chloromonas is the only distinguishing feature separating it from Chlamydomonas. Ettl recently transferred numerous species from the genus Chlamydomonas to Chloromonas. No molecular or biochemical data are available

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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