This large, elegant foliose lichen is like beautifully crafted porcelain when dry. It is non-isidiate and composed of numerous, wavy, overlapping lobes with a lead grey, finely ridged, matt or shiny textured thallus. Sessile discs are common, red-brown with thin, wrinkled persistent rims. It grows on sheltered trees such as old ash boles and hazel often by streams; also on rocks and boulders. In Ireland, it is restricted to County Kerry and to the Burren, County Clare.

Key characteristics

  • Thallus lead grey, non-isidiate with overlapping lobes finely striated
  • Discs red-brown; very local.
