Description of Limnomonas gen. nov., L. gaiensis sp. nov. and L. spitsbergensis sp. nov. (Chlamydomonadales, Chlorophyta)
Two novel Chlamydomonas -like species, belonging to the Moewusii clade, have been described. The first species inhabits eutrophic and neutral to basic pH waters in Sweden and England. It is easily recognizable under a light microscope due to its morphology (a small green prolate spheroidal shape wit...

Two novel Chlamydomonas -like species, belonging to the Moewusii clade, have been described. The first species inhabits eutrophic and neutral to basic pH waters in Sweden and England.
