Description: This red-fruiting cup Cladonia is a colonist of acid peat and moorland especially at high altitudes. The cups develop from stout stalks (podetia) that are covered with yellow-green warty granules. Wide-mouthed cups carry the scarlet discs on their rims, which may expand to cover the cup. It is widespread in Ireland.

Key Identification Features:

• The presence of cups and the green-yellow surface of small warty granules serve to distinguish this common Cladonia species
• The podetia are often misshapen.
