This is an epiphyte of small twigs and branches and platy acid bark at the base of trees in damp woodland. The small brown thallus is composed of tiny flattened squamules with pale green to yellow soralia forming along the edges. Discs are absent. Spot tests: Pd+ red. The combination of the brown squamulose thallus and yellow green soralia are usually sufficient to identify it. The species is known from central Northern Ireland and the counties of Cork and Kerry.

Key characteristics

  • Thallus brown, areolate, the areoles squamule-like; Pd+ red, K-, C-
  • Soralia erupting from surface or edge of squamules, green to yellow, sometimes spreading but never crust-forming.
