Planoprotostelium (plan-owe-pro-toe-steal-ee-um) is a true myxomycete (or closely related to the true myxomycete), there is a flagellated stage typically with a single flagellum but occasionally a rod or filament may project from the front end of the cell. The flagellate body is very amoeboid and may have uroidal filaments projecting from the back end. The species may also become an amoeba (top right) and may produce a stalk and encyst at the top of that stalk. Contractile vacuoles (white) nuclei with nucleoli (some cells have more than one) are visible. Phase contrast.
