In old woodlands and along wooded ravines this epiphyte occurs around the mossy bases of mature, deciduous trees such as ash and oak. It has a generally green, granular-mealy thallus with pale, orange-pink to reddish-brownish discs (0.4-1.2mm diam.) that become increasingly ‘boxing glove’ globose with age often occurring in tight, knobbly clusters. All reactions negative. North-west and west Ireland.

Key characteristics

  • On the mossy trunks of mature ash and oak trees for example, along sheltered valley bottoms
  • Thallus of mealy green granules; discs orange-pink to pale brown, becoming spherical.
