The smooth, slatey-grey-green, blue-tinted thallus of this species assists greatly in its identification, especially as it may easily be overlooked as a poorly developed version of Fuscidea cyathoides were it not for the habitat of hard, exposed limestone. The spherical discs (perithecia) are very often completely immersed in the thallus; many are sterile. In Ireland it occurs locally on the limestones of Counties Clare (Burren), Galway, Sligo and Leitrim.

Key characteristics

  • A species not unlike V. baldensis but with a bluish, dark grey-green thallus
  • Perithecia immersed, often sterile.
