This crustose epiphyte will be instantly recognised by its numerous, small, cream or ivory-white discs (0.2-0.7mm diam.) scattered across a pale-green-white thallus. It is a lichen of the wettest and most nutrient-poor, hyperoceanic woodlands where it enters into association with other Micarea species, Mycoblastus sanguinarius, Megalaria pulverea and larger foliose lichens such as Hypotrachyna laevigata. Thinly scattered; largely absent from eastern and central Ireland.

Key characteristics

  • Small, cream or ivory-white discs on a pale-green thallus
  • On oak, alder, birch and other acid-barked trees in western hyperoceanic areas of Ireland.
