This lichen should be compared very closely with P. pastillifera (described elsewhere) which is almost identical and found in similar habitats. P. tiliacea has a slightly bluer thallus and may have some frosting on the lobes. The isidia are pale brown (not blackened), cylindrical or coralloid and are not attached to a short stalk. Discs are rare. Occasional; southern and south-east Ireland.

Key characteristics

  • Blue-grey thallus with some frosting on the lobes; densely isidiate
  • Unstalked, coralloid, pale brown isidia.
