Very like C. crenularia (described elsewhere) but is an epiphyte with a paler grey thallus and larger discs (to 2mm diam.) most frequent on hazel and in willow swamp. It may also be found on the main trunk of trees with a basic bark. It appears to have increased its range significantly in recent years.

Key characteristics

  • The large, bright orange fruits on a thin, immersed and insignificant thallus on tree bark indicate this species
  • It is one of only a very few members of the genus that in Ireland grow as epiphytes.
