Ultrastructural studies revealed that Chlorosarcina stigmatica Deason differs from C. brevispinosa and C. longispinosa Chantanachat and Bold because the vegetative cell possess a pyrenoid, and the zoospores have chlorophycean characteristics. Zoospores of the latter species exhibit pleurastrophycean characteristics including counterclockwise absolute orientation of the flagellar apparatus components. Nuclear division in C. longispinosa, like that of Friedmannia israelensis Chantanachat and Bold, is metacentric. It is suggested that a new genus, Desmotetra, be erected for Chlorosarcina stigmatica, and that it, along with Chlorosarcinopsis Herndon, be placed in the Chlorococcales, Chlorophyceae. Chlorosarcina brevispinosa and C. longispinosa belong in the Pleurastrales, Pleurastrophyceae.
