Strongly photophobic, this lichen inhabits shaded, siliceous, rocky habitats such as the piles of pebbles and boulders deposited around the edges of loughs and tarns including coastal sea loughs. The give-away clue to this species is the glaucous thallus developed over a white prothallus. Discs are beige or pink. Furthermore, when sterile, the species has distinctive white-pubescent pycnidia and a UV + pink thallus. Where it occurs, it is frequently accompanied by B. trachona. In Ireland, present in Counties Kerry and Galway; also north coast.

Key characteristics

  • Glaucous-green, felt-like thallus developed over a white prothallus
  • Sterile material has white, furry pycnidia and a UV+ pink thallus.
