Abstract

The cell structure of the freshwater chrysomonad Spumella sp. has been studied. The cell contains a vesicular nucleus, mitochondria with tubular cristae, Golgi apparatus, flagellar roots, and wide dorsal microtubular band. The flagella bear the spiral of four to five coils in the transitional zone. The rudiments of mastigonemes have been found in the perinuclear space. The compact leucoplast has an amorphous core surrounded by the membrane. No stigma has been detected. The leucosin vacuole, rhizoplast, and swelling of the short flagellum are absent. One to three osmiophilic granules lie near the leucoplast. The contractile vacuole is surrounded by tubules. The resemblance and difference of investigated flagellate with other chrysomonads are discussed.
