The white-pink thallus of this species resembles a Lepraria in its thick, soft, blistered, tent-like, slightly lobed appearance and in its rarely seen discs. It grows below dry, sheltered, coastal acid rocks, including boulders, especially those gaping at the base. The thallus is C+ red. It is unlikely to be confused with Dirina which has a denser and thicker thallus. In Ireland, it has been recorded from Counties Kerry, Cork and Sligo.

Key characteristics

  • White-pink when fresh, soft, blistered like a low-pitched tent or heavily wrinkled like brain-tissue; C+ red
  • Lepraria-like; in shaded underhangs and below gaping boulders that have settled unevenly.
