This lichen is associated with mosses on siliceous rocks and tree boles in hilly areas. It produces abundant small, flat, pale brown discs with a raised rim rapidly excluded with age. The simple spores separate this species from L. hypnorum which has darker discs and broader, septate spores. Throughout Ireland.

Key characteristics

  • Thallus pale grey-brown, membranous like fine silk dissolved on to moss; discs pale brown, abundant, at first with a margin but later excluded
  • Spores simple, narrow 9-14ųm long.
