Very like Micarea lignaria but with smaller, consistently three-septate spores and habitat of coastal rocks and scattered stones. It should be noted that this is an arctic species; its taxonomy is suspect; a revision of its true identity is overdue. In Ireland, the species is known from Connemara.

Key characteristics

  • In appearance very similar to M. lignaria
  • Spores no more than three-septate and smaller in length (<22Ám) than in that species; coastal rocks.
