This is a scarce lichen of dry, mossy rocks growing on mildly basic underhangs by upland streams and waterbodies in the west of Ireland. The discs of Strigula resemble Porina in their spherical (perithecial) form. S. confusa has a thin, whitish-grey thallus with the globose discs almost completely immersed. The large muriform spores are 40-58Ám long. It is known from Mt. Brandon, south Kerry and the Assarnacally River, west Donegal.

Key characteristics

  • Overgrowing mosses on mildly basic rock underhangs by upland streams and tarns
