The clue to identifying this variety is in the size of the thallus which is often no more than a thin cover of grey squamules with an even paler edge. Well-grown material may sometimes be stalked, but these are dwarfs only a few millimetres tall, edged with granular soralia. It is tolerant of some pollution and should be searched for in urban areas on low wall tops and the like. Dingle Peninsula, County Kerry.

Key characteristics

  • Thallus reduced to a thin cover of grey squamules; stalks (pseudopodetia) very small and often absent, capped with soredia
  • Urban walls.
