This is a relative newcomer to the Irish lichen flora. It will grow on acid rock debris and screes in the uplands as well as on the bark of acid-barked trees and shrubs including gorse scrub. The eye-catching feature is the small, extremely neat, green, punctiform soralia which produce green soredia with blue-grey speckles. Discs are rare. The thallus and soralia turn C+ red. Local; throughout Ireland.

Key characteristics

  • Neat, green, punctiform soralia on a grey-brown to grey-green thallus; somewhat like Trapelia corticola in size and habit
  • C+ red; gorse and heather stems, damp acid bark, sheltered acid screes.
