Description: The yellowy, grey-green granular crusts of this species bearing large, cup-like, blackened sessile discs with thick, brownish crumpled margins occur only very locally in Ireland. It is an upland lichen of damp siliceous rocks and pebbles best searched for along moist gullies below the peaks of the Wicklow Mts, Antrim Hills or the coastal mountains of Donegal.

Key Identification Features:

• Yellowy-grey, bubbly-granular thallus with large, blackened cupped discs
• Upland lichen of moist gullies; often where snow lies late in the mountains.
