''Polytoma'' is a genus of green algae, specifically of the Chlamydomonadaceae. ''Polytoma'' is a genus of colorless, free-living chlorophytes similar in form to ''Chlamydomonas'' but lacking chlorophyll. Two flagella emanate from the anterior papilla of the cell, and cells have two contractile vacuoles at the flagellar base. ''Polytoma'' possesses a leukoplast in place of a chloroplast, in which many starch grains are concentrated; there is no pyrenoid. Since they lack photosynthetic capability, ''Polytoma'' species are entirely saprotrophic, obtaining nutrients from decaying organic matter. Some species possess an eyespot apparatus (stigma) in the anterior portion of the leucoplast, but in others this organelle is absent.〔Smith, G. M.
