S. pruinosum is an epiphyte of young oak trees in dry but well-established woodlands. It is unmistakable in appearance with abundant, tiny, frosted, white to pink globose discs on a soft, spreading, minutely granular, white-crustose thallus. In Ireland it is rare, occurring only in Counties Waterford, Wicklow and Longford.

Key characteristics

  • The abundantly clustered, ivory-glazed, spherical discs on a white spreading thallus are distinctive and quite unlike any other Irish lichen species
  • Usually on young oak trees in dry, sheltered woodlands often along the edge of tracks or rides.
