Leptomyxa reticulata
Arboramoeba cf reticulata – Photomicrograph: Ernst Hippe, Germany

Ernst Hippe, who took the photomicrographs on this page, noted for this amoeba: “I found specimens of these species on several locations: a wet cactusflowerpot and dish, water on a forest trail, peat bogs and bromelias. Often they showed a slow changing from a belt-shape form into a plasmodium. The belt shaped forms were 500 – 2500 µm long and about 7 µm broad. They could show a stationary plasmodium for a long time or they moved about 100 µm/h. The plasm is very bright without much contrast. A distinct movement of granules was visible. Numerous contractile vacuoles, max. 3.5 µm in diameter.”
