A number of species are adapted to living on snow, making them [snow algae](/source/snow_algae). The most northerly location at which this algae has been observed is Lake Bienville, Quebec, 55°N.{{cite book|title=Proceedings of the Annual Meeting - Eastern Snow Conference|url=https://books.google.com/books?id=H60sAQAAMAAJ|volume= 57, Part 2000|publisher=Eastern Snow Conference|page=209}} == Description == ''Chloromonas'' is a unicellular organism with cells that are ranging from spherical, ovoid, cylindrical, or spindle-shaped. There are two equal [flagella](/source/flagella) on the anterior end of the cell, with or without a papilla. As single large [chloroplast](/source/chloroplast) fills the cell, and may be cup-shaped and variously lobed. Chloroplasts lack [pyrenoid](/source/pyrenoid)s. An [eyespot](/source/eyespot_apparatus) is present in most species. There is a single nucleus typically embedded in the center of the cell.{{AlgaeBase genus|id=43373|name=Chloromonas|access-date=2023-12-27}} Reproduction in ''Chloromonas'' occurs asexually and sexually. Asexual reproduction is by cell division, forming two or four [zoospore](/source/zoospore)s. Sexual reproduction in the genus is diverse and can be isogamous, anisogamous, or oogamous. == Taxonomy == Traditionally, the genus ''Chloromonas'' has been defined morphologically as being a pyrenoid-less version of ''Chlamydomonas''. Phylogenetically, the pyrenoid-less species are all found in a single [clade](/source/clade), but there are also pyrenoid-bearing species within this clade, making the genus non-monophyletic. In 2001, as a first step towards revising the genus, [Thomas Pröschold](/source/Thomas_Pr%C3%B6schold) and colleagues emended the [circumscription](/source/circumscription_(taxonomy)) of ''Chloromonas'' to include all species of this clade.{{cite journal|doi=10.1078/1434-4610-00068 |title=Molecular Phylogeny and Taxonomic Revision of ''Chlamydomonas'' (Chlorophyta).
