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. This picture was taken by David Patterson, Linda Amaral Zettler, Mike Peglar and Tom Nerad from cultures and other materials maintained at the American Type Culture Collection during 2001.
