Old, dry bark of heavily shaded wayside trees, in old churchyards or those lining the driveways of old estate properties not contaminated with dust, should support this species. The vivid yellowy-green, crumbly crusts (of coalescing soredia sometimes forming patches of over 20cm across) are an instant giveaway. It is also found on trees in humid woodlands along estuaries, for example. Mainly north, east and south of Ireland.

Key characteristics

  • Yellowy-green crusts on dry, heavily shaded bark of old trees, for example, lining the side of drives, etc.
  • Occurs with Enterographa crassa, Schismatomma cretaceum, Pyrenula and Opegrapha lichens mostly.
