The Chlorellales include mostly freshwater or terrestrial (rarely marine), coccoid algae.^[2] Molecular phylogenetic studies mostly tend to find Chlorellales to consist of two sister clades, corresponding to Chlorellaceae and Oocystaceae; however, in some studies the two are not sister to each other, making Chlorellales not monophyletic.^[3]

Genera of uncertain placement include:^[4]

• Ankistrodesmopsis
• Edaphochloris
• Picochlorum
• Uvulifera
