Micrasterias furcata C.Agardh ex Ralfs 1848
Most likely ID: n.a.
Basionym: n.a.
Add’l Synonyms: Micrasterias radiata Hassall ex West & G.S.West 1905
Description: The cells are about as long as wide and have a circular shape. The cell halves consist of three lobes. The lateral lobes are clearly separated. At the ends of the lateral lobes there are two outwards standing projections. Between the projections there is a concave area. The central cut is deep and peripherally strongly widened.
Dimension: Length (140)–150–200–(250) µm, width (120)–140–170–(210) µm, L/W (1.0)–1.1–1.2–(1.25).
Occurrence: In acidic to moderate acidic fens and bogs. Ubiquitous, rather rare in Central Europe.
