This loosely attached, brown, leafy lichen is a common sight on siliceous rocks, boulders and scree in upland and mountain districts. The lobes often with a metallic sheen carry a fine tracery of white lines. Powdery material on the surface of the lobes (soredia) or rod-like projections (isidia), common in many other species, are here both absent. Reddish-brown discs are often present. It may occasionally be found on acid-barked trees.

Key characteristics

  • The brown colour, combined with a lattice work of white lines on the lobes, serves to separate this similar species
  • It lacks both isidia and soredia.
