Look for this tiny lichen among wall cushion mosses or on old or crumbling mortar. Closely resembles L. polyanthes (described elsewhere), but differs chiefly in the granular-nodulose thallus (not spreading-lobate); discs pore-like at maturity and larger spores (20-33ųm long).

Key characteristics

  • Thallus tiny, granular-nodulose, only expanding to form the pore-like discs with large spores
  • Among cushion mosses on walls; also on crumbly mortar.
