Non-filamentous desmid. The depht of focus picture shows a cell with stelloid chloroplasts and abundance of lipid drops. Zip archive includes also the topmost picture of the DOF stack. Picture generated from 11 shots using CombineZ by Alan Hadley, MicroPicS by Bernhard Wiedemann and Photoshop. For details see ZIP archive. Sample from sphagnum pond Dosenmoor near Neumuenster (Schleswig-Holstein, Germany). Images were taken using Zeiss Universal with Olympus C7070 CCD camera.

Xanthidium antilopaeum (BREB.) KÃTZ. var. crameri GRÃNBLAD The cells are a little wider than long and octagonal in coarse shape. The central cut is deep and extends strongly outwards. The cell halves are oblong hexagonal with straight or weakly concave sides, the vertices are broadly truncated. At each lateral and apical angle a pair of long pricks originate. Above the center is a flat, often slightly brown colored swelling of the cell wall occupies with small warts. Length without pricks 50 - 60 µm, width without pricks 58 - 63 µm. Occurrence: In littoral zones of mountain lakes in Central Europe rather rarely.

Non-filamentous desmid. The depht of focus picture shows a cell with stelloid chloroplasts. Multi layer image (DOF) using about 65 frames generating depth of focus, stacked manually using Corel Photopaint. Sample from sphagnum pond Dosenmoor near Neumuenster (Schleswig-Holstein, Germany). This image was taken using Zeiss Universal with Olympus C7070 CCD camera.

Xanthidium cristatum BREB. In RALFS The cells are little longer than wide, octagonal in coarse shape with straight or weakly concave sides. The central cut is strongly extended outwards. On each side of each cell half origins one prick . The lateral and apical angles likewise have one pair of pricks each. In the center of the cell halves is flat, hemispheric swelling. Length without pricks 50 - 55 µm, width without pricks 40 - 43 µm. Occurrence: In Central Europe sporadic in moderate acidic waters of fens, siltation zones et cetera.

Xanthidium armatum (BREB.). RABENH. ex RALFS The cells are 1.5 times longer than wide and rectangular in shape. The cell halves are octagonal with 6 pairs of furcated processi. In the center of the cell halves is a star shaped branched processus. The cell terminations are broadly truncated. The central cuts are deep and strongly broadened towards the periphery. Dimension: Length 100 â 140 µm, width 120 â 180 µm Ecology: As acidophilic alga common in acidic sphagnum bogs. Occurrence: Ubiquitous
