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.
