Known as ‘oak moss’ and widely harvested on the continent for use in the perfume industry, this familiar lichen forms yellow-green to grey, ragged, hanging tufts about the length of a little finger. The antler-shaped branches are flattened, strap-like and white below. Mature lobes are edged with spots of powdery-white soredia (a mixture of fungal hyphae and algae). The whole plant is anchored by a holdfast-like sheath. Frequent on acid-barked trees and old wooden fencing; rare on rocks.

Key characteristics

  • Upper surface yellow-green but white below
  • The broadly flattened branches form hanging tufts.
