Sarcogyne hypophaea (Ach.) A.Massal.

Description: This species, which is relatively frequent in south-east Ireland, is a miniature version of S. clavus with discs to 1mm diam. On siliceous tomb-tops in damp churchyards it can grow to become a dominant feature. The greyish thallus supporting pale-red to brown discs with a black, compressed rim and multispored spore-sacs (asci) (seen in a microscope squash of the discs) are its main characteristics.

Key Identification Features:

  • Thallus inapparent or greyish, discs, pale red to brown with black angular rim (exciple)
  • Spores 3.5–5µm long; on smooth, horizontal siliceous rock, for example, tombs, memorials.
