This rather waxy, white-grey, smooth to finely-warted crustose epiphyte is a species of both bark and wood. Chemical tests will show it to be K (Potassium hydroxide test) and C + pale yellow (fresh bleach test). Through a hand lens, soredia will be seen spilling onto the surface in little lines or ridges. Full developed specimens may appear covered in a finely granular, grey crust. Discs are uncommon. If growing on wood, then it is usually on the top surface of wooden railings. North-west Ireland, uncommon.

Key characteristics

  • Waxy, white-grey thallus, K -, C + pale yellow (C + red in O. microstictoides)
  • Finely granular soredia reach the surface in lines or ridges.
