Vertical acid outcrops in the uplands are the places to search for this species. The distinctive discs (0.3-0.5mm diam.) which are often abundant are each rimmed with a circle of white, thus resembling a halo. The thallus is grey-brown so the halo-rimmed disc-exciple shows up clearly against it. Local and scattered: Counties Waterford, Wicklow and Donegal.

Key characteristics

  • Dark grey-brown thallus with small raised discs surrounded by a halo-like margin
  • Steep, vertical acid rocks and cliffs, especially along the sides of upland valleys.
