Leptomyxa (lep-toe-mix-a) is an amoeba which can be quite large. Typically with an extended body form with thick strands of cytoplasm forming a network. Individual pseudopodia tend to be fine and tapering. This high magnification image shows the nature and texture of the cytoplasm, with a granular consistency reminiscent of vampyrellid amoebae) and many nuclei. From soils. Differential interference contrast.
