Chlorophyceae. , the type family Chlorococcaceae was placed in the order Chlamydomonadales. 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 The Trebouxiophyceae, also known as trebouxiophytes, are a class of green algae, in the division Chlorophyta. Members of this class are single-celled, colonial, or multicellular and are found in freshwater, terrestrial or marine habitats worldwid ...

Ulvophyceae The Ulvophyceae or ulvophytes are a class of green algae, distinguished mainly on the basis of Ultrastructure, ultrastructural morphology, Biological life cycle, life cycle and molecular phylogenetics, molecular phylogenetic data. The sea lettu ...

Chlorophyta Chlorophyta is a division of green algae informally called chlorophytes. Description Chlorophytes are eukaryotic organisms composed of cells with a variety of coverings or walls, and usually a single green chloroplast in each cell. They are ...

Desmidiales Desmidiales, commonly called the desmids (''Gr.'' ''desmos'', bond or chain), are an order in the Charophyta, a division of green algae in which the land plants ( Embryophyta) emerged. Desmids consist of single-celled (sometimes filamentous or ...

Families

According to Komárek & Fott (1983): * Chlorococcaceae ( Chlorococcoideae, Spongiococcoideae) * Palmellaceae ( Hormotiloideae, Palmelloideae, Neochloridoideae, Chlorosarcinoideae) * Chlorochytriaceae * Dicranochaetaceae * Characiaceae ( Fernandinelloideae, Characioideae, Schroederioideae) * Treubariaceae * Golenkiniaceae * Hydrodictyaceae * Micractiniaceae * Botryococcaceae ( Dictyosphaerioideae, Ecballocystoideae, Botryococcoideae) * Radiococcoideae ( Radiococcoideae, Disporoideae, Dictyochlorelloideae, Palmodictyoideae) *

Oocystaceae Oocystaceae is a family (biology), family of green algae, in the class Trebouxiophyceae. Molecular phylogenetic studies mostly (but not always) place the family in the order Chlorellales, as sister to Chlorellaceae. The Type (biology), type genus ...

( Lagerheimiodeae, Oocystoideae, Eremosphaeroideae, Glaucocystoideae) * Chlorellaceae ( Siderocelidoideae, Chlorelloideae, Ankistrodesmoideae, Tetraedronoideae, Scotielloideae) * Coelastraceae * Scenedesmaceae ( Coronastroideae, Danubioideae, Crucigenioideae, Tetrallantoideae, Scenedesmoideae, Dimorphococcoideae) According to Smith (1938): * Chlorococcaceae * Endosphaeraceae * Characiaceae * Protosiphonaceae * Hydrodictyaceae * Oöcystaceae * Scenedesmaceae
