Chlorococcales
Template:Short description Script error: No such module "Distinguish".
Chlorococcales is a formerly recognized order of green algae in the class Chlorophyceae. since February 2022[update]Template:Dated maintenance category (articles)Script error: No such module "Check for unknown parameters"., the type family Chlorococcaceae was placed in the order Chlamydomonadales.[1]
Conventionally, many groups of coccoid green algae were lumped in the order Chlorococcales sensu lato by Komárek & Fott (1983), based on Pascher's (1918) idea of establishing orders according to life forms. However, coccoid green algae are currently placed in several orders of Chlorophyceae, Trebouxiophyceae, Ulvophyceae (e.g., Chlorocystis) and Prasinophyceae within the division Chlorophyta, or in the division Charophyta (e.g., Chlorokybales, Desmidiales).[2]
