This crustose seashore lichen begins its life as a parasite of Lecanora gangaleoides, eventually developing an independent, lead-grey to blue-grey, shiny, C+ red, cracked thallus, punctuated by rounded and immersed discs. Its distinctive colour attracts attention in the field. In Ireland, it is very local in Counties Sligo and Waterford.

Key characteristics

  • Thallus, lead- or blue-grey, shiny, cracked into tiny ‘islands’, each with an immersed disc with a dimple in the top
  • On well-lit, siliceous rocks along the seashore (rare, though possibly under-recorded).
