This iconic oceanic species is relatively frequent in well-established deciduous woodland, hazel coppice and willow swamp in the west. It is a shiny, leafy, intermediate brown to grey-brown lichen with a characteristic wrinkling to the lobes and lobe ends where the discs develop only on the undersides. The internal layer (the medulla) is yellow, reacting K + purple.

Key characteristics

  • When fertile, the brown fruits that are curled under the lobe ends of the lichen are immediately characteristic
  • Nephroma parile rarely supports discs and is sorediate with small granules on the lobe margins and scattered over the surface that are the same colour as the thallus.
