Very similar in external appearance to C. modesta (described elsewhere), but the discs are constricted or shortly-stalked below and are generally up to twice the size (to 0.8mm diam.). It has a specialized habitat of growing under damp overhangs of calcareous rock such as limestone and schist. In Ireland the species was formerly known from two sites in Connemara, County Galway but has not been seen since 1926, so is worth the search.

Key characteristics

  • Like C. modesta but discs larger, pinched below almost stalked
  • Grows under damp overhanging limestone or calcareous schist.
