Mayorella has characteristic v-shaped pseudopods. The inset in higher magnification shows the nucleus with the central nucleolus (high resolution optics Planapo 40/1,0 oil). The scale bar indicates 50 µm. 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.
