flagellate

Description:

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 as may be seen here. The flagellate body is very amoeboid and may have uroidal filaments projecting from the back end. Phase contrast.
