This crustose lichen has a thin, barely wrinkled, smooth, creamy-grey to very pale green thallus hardly zoned at the edge. The fruiting discs occur mostly singly so are single-pored; they are not as neatly pinpricked or as close-set as in P. pertusa and are flatter in shape rather like putty-soft beads trapped below a skin of elastic. It is essentially a species of sheltered, smooth-barked, broadleaved trees.

Key characteristics

  • Creamy-grey thallus with shiny surface
  • Discs, flattened-warty, not congested, mostly in ones with a visible pore.
