Netrium interruptum (BREB.) LÃTKEM. The cells are 4-5 times longer than wide. The central part is cylindrical and gradually converging towards the broadly rounded off ends. The terminating vacuoles are big with a spherical crystal each. The chromatophores are clearly partitioned in four segments. Dimension: Length 200 â 350 µm, width 30 â 70 µm Ecology: Sporadic in little acidic fens and bogs, in addition, in the plankton of oligotrophic lakes. Occurrence: Ubiquitous, apart from Australia

Netrium digitus has stelloid chloroplasts with pyrenoid grains at the center axes of the two chloroplasts. This high resolution depth of focus picture using Planapo 63/1.4 gives a synoptic view at the tongues of stelloid chloroplasts, the nucleus situated in center of the cell and (look at higher magnification inset) mitochondria on inner surface of cell wall (light circular dots). Another DOF taking in zip archive showes median layer with nucleus and pyrenoids. Scale bar indicates 25 µm. See zip archive for high resolution details. Sample from spagnum pond situated in the northern alpine region of Austria near Salzburg. Images were taken using Zeiss Universal with Olympus C7070 CCD camera.
