Description: Recorded only from County Wicklow, this species is similar to P. badia but with a paler brown thallus, banded margin when young and numerous tiny, speck-like pycnidia. It should be searched for in the grey zone of coastal siliceous rocks where it often overgrows other crustose lichens such as Aspicilia species.

Key Identification Features:

• Like P. badia but differing in the paler colour, numerous pin-prick-sized pycnidia and dark thallus edge
• On grey-zone acid sea-cliff rocks, sometimes overgrowing Aspicilia cinerea.
