This epiphyte is an occasional species of nutrient-rich wayside trees in Ireland. The rather warty, grey-green thallus supports dense clusters of beige to orange-pink discs that become increasingly convex with age. Spores are needle-shaped, three- to seven-septate. The discs are much paler than in B. rubella and B. assulata. All of the Lecania lichens differ in their zero- to one-septate spores. In Ireland, the lichen is widespread throughout.

Key characteristics

  • Discs (0.2-0.5mm diam.) are beige- to orange-pink, distinctive, mostly convex
  • On rough-barked, wayside, nutrient-rich trees; along roads near edge of settlements.
