Xanthidium Ehrenberg ex Ralfs 1848

Description: The cells are little wider than long and almost square in shape. The central cut is deep and extends strongly outwards. The cell halves are stretched octagonally with broadly rounded ends. At the cell sides there are two broadly blunted, conical extensions and a hardly visible projection on both sides of the cell vertices. In the center of the cell halves is a flat swelling, which is covered with small warts or dimples. From this alga only three illustrations exist so far: BOLDT (1888), LARSEN (1907) und GRÖNBLAD (1952).Dimension: Length 60–63 µm, width 65–68 µm.Occurrence: Known only from Greenland so far.Left: Original graphic by Prof. Lenzenweger.Right: Photomicrograph by Prof. Lenzenweger. For microphotography, the microscope illumination was adjusted in such a way that as many features as possible that are important for species identification are prominently displayed.Copyright by Prof. Rupert Lenzenweger, Ried im Innkreis, Austria.© Wolfgang Bettighofer,images under Creative Commons License V 3.0 (CC BY-NC-SA).For permission to use of (high resolution) images please contact postmaster@protisten.de.For further information about the image, please click here: Link to protisten.de page

Description: 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.Dimension: Length 45–55 µm, width 35–45 µm (without pricks).Occurrence: In littoral zones of mountain lakes in Central Europe, rather rare.Left: Original graphic by Prof. Lenzenweger.Right: Completed binary fission.
