The large, wavy lobes are grey-brown when dry but turn bright green when wet and have dark wart-like cephalodia tightly attached to the upper surface. The undersurface is pale near the margins but dark in the centre with dark rhizines and a network of dark veins. Apothecia are infrequent, the spores 3-7 septate.

Usually found among mossy, calcareous rocks with most Irish records from Counties Clare and Sligo

Similar: Peltigera britannica is very rare with loosely attached cephalodia, no network of dark veins under the lobes and has never been found fertile in Europe
