The light grey, white-speckled, foliose, rosette-forming thallus of this species with a ‘frilly’ thalline edge and abundant black, grey-frosted discs makes this a distinctive and attractive lichen of well-lit twigs and branches of nutrient-rich trees such as sycamore, ash and poplar.

Key characteristics

  • Pale grey, ‘frilly’ edged thallus with abundant white, pinprick spots and contrasting large black roughly circular discs
  • Stands out like no other lichen when growing on the knobbly twig ends of hedgerow trees or on smaller branches.
