Description: In areas of natural limestone this shade-loving, crustose lichen will be growing nearly everywhere in deep crevices and underhangs frequently with Verrucaria elaeina and leprose lichens. The scurfy thallus is only a few centimetres wide, usually pale green, and easily overlooked as a stain. The discs are small (0.2-0.5mm diam.) in colours of beige or orange-pink; it is this which will attract your attention. Mainly western Ireland (County Clare)

Key Identification Features:

• Discs orange-pink or beige on a greenish thallus; natural limestone crevices
• On limestone rock: shaded faces, dry underhangs, crevices, deep hollows and at the base of limestone boulders where they make contact with the ground.
