L. aipospila is a common sight in most maritime districts of Ireland where its spreading, coarsely-warted, crustose patches, usually of a grey-brown to purplish colour, or pale brown and indigo-black, are conspicuous on weakly basic to weakly acidic, sheltered cliff outcrops wetted with seepage or mild nutrient. Patches can grow to sizeable proportions sometimes coalescing into sheets. Discs common, red-brown to black. Coastal Ireland; rare in the east.

Key characteristics

  • Crustose, warted thallus, grey to brown with purplish highlights often forming extensive colonies
  • On tilting platforms of relatively neutral rock on sheltered cliffs where there is seepage.
