The Trebouxiophyceae, also known as trebouxiophytes, are a class of green algae, in the division Chlorophyta.[2] Members of this class are single-celled, colonial, or multicellular and are found in freshwater or terrestrial habitats worldwide. Many taxa in the Trebouxiophyceae form symbiotic relationships with other organisms; in particular, the majority of phycobionts within lichens are trebouxiophytes.[4] A number of taxa have also lost the ability to photosynthesize, and have evolved to become parasitic; examples include Prototheca and Helicosporidium.[3]

Trebouxiophyceae was originally defined by ultrastructural characteristics, such as having basal bodies of its flagella in a counterclockwise orientation, non-persistent spindles during telophase, and phycoplast-mediated cytokinesis.[5][3] It is now generally circumscribed based on phylogenetics, particularly based on the 18S rDNA locus.[4]

Genera without intervening taxonomy include:

Choricystis
Crucigenia
Koliellopsis
Leptosira
Rhopalosolen
Viridiella
