Arthonia anombrophila is closely allied to A. pruinosa, A. zwackhii and A. stellaris (described elsewhere) but is separated by its C-, white-frosted (pruinose) discs, smaller spores (12-14ųm long on average with enlarged upper cell) and negative chemistry. It grows chiefly on dry, roughened bark (for example, oak), especially near the base of trees in old estate parklands, or along avenues or by waysides. Northern half of Ireland and at scattered localities along the south coast. Absent from the oceanic west.

Key characteristics

  • C-, white-pruinose discs and with smaller spores than its lookalikes
  • Usually confined to the base of old trees with rough bark.
