This species grows on dry rock underhangs, stones and roots etc. in valley woodlands; also the undersides of large siliceous boulders. The scurfy green-grey thallus is usually richly fertile. The convex discs vary from very pale grey, piebald or blue-grey to almost black. Despite this range of colouration, internally both the upper and lower hymenium remains colourless (K-), rarely brownish-green. Spores are simple, ellipsoid. In Ireland, M. bauschiana is thinly scattered.

Key characteristics

  • Thallus scurfy, green-grey; discs abundant, convex, externally ranging from pale grey through to black; hymenium mostly colourless, pores simple
