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.

Multicilia marina Cienkowski, 1881. Cells are normally spherical in a culture, about 30-40 microns in diameter, however,some cells attain an oblong or irregular form. The majority of cells possess 20-30 long flagella, 1.5-2 times the cell diameter. The flagella differ from those of other heterotrophic flagellates by very weak movements, resulting in a similarity to heliozoan axopods. The locomotion of M ulticilia is slow, rotatory, without any definitive direction, therefore moving cells normally lack anterior and posterior ends. Cells glide in one direction for a very short distance and may change direction rapidly (including moving backwards). The cell rolls over when changing direction. The temporary anterior flagellum is then stretched and clasped along the substratum, only its apex continues to oscillate. The temporary posterior flagellum shows the same behaviour. Other flagella perform irregular movements without any visible coordination. After changing the salinity, cells become free floating and continue a weak oscillation of the flagella.

Enteromyxa paludosa cell was showing very colorful metabolites and numerous nuclei and contractile vacuoles. In order to deliver depth of focus 50 high resolution frames (Planapo 63/1.4) were processed. The picture inserted showes 4 nuclei and two contractile vacuoles in higher magnification. Sample from sphagnum pond situated in the northern alpine region of Austria near Salzburg. Images were taken using Zeiss Universal with Olympus C7070 CCD camera.

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.
