Description: In mountain country a quick search of siliceous rocks and boulders may soon reveal the presence of this species which is adorned with blood-red discs. The large, fertile, pale green to grey, warted crusts are consequently, highly conspicuous. Spot tests: K+ yellow, Pd+ orange. Local; chiefly north-west and south-east Ireland.

Key Identification Features:

• An easy lichen to recognise on account of its blood-red discs and warty thallus
• On acid rocks in mountainous country; Pd+ orange.
