Description: The cells are appr. two times longer than wide. The cell sides are loboid broadly rounded. The vertex lobes are protruding clearly, broadened on the ends and with a cut in the middle. In the center of the cell halves there are pairs of bumps which are covered with small warts. The central cuts are far opened towards the periphery.Dimension: Length 55–80–(95) µm, width 30–45–(52) µm, L/W: (1.5)–1.7–2–(2.2).Occurrence: Ubiquitous, prefers boreal areas (mountains), rather rare in Central Europe. Acidophilic alga in shallow waters between sphagnum.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 (1.3)–1.4–1.6–(1.7) times longer than wide, broadly elliptical in shape. The lateral line of the shape showes soft ripples with horny ends. Cells are lightly tapered towards the rounded periphery with fine cuts in the middle and denticles on both sides. The incision in the middle of the cell (called sinus) runs deep and is straight-lined. At each center of the cell halves lies a thin swelling with a pattern of oblonged verrucae. Further nipples spread over the cell wall. Chloroplasts with few tiny pyrenoids.Dimension: Length (23)–27–40 µm, width (14)–17–22–(26) µm.Occurrence: Widely spread in acidic and middle acidic waters, in alpine regions up to altitude of 2000 m.Left: Original graphic by Prof. Lenzenweger.Right: Photomicrograph by Prof. Lenzenweger.
