R. teichophila may usually be recognised by its thick, grey-black, granular thallus and immersed discs, the rim, part of the thallus. It can grow both on acid and weakly calcareous rock, usually memorials and walls, but is less frequent in more natural habitats. In relative terms the discs are large, reaching 1.25mm diam. Under the microscope, the large spores (2030 x 1119m) are thick-walled. In Ireland, the species is rare.

Key characteristics

  • Thallus grey to black, rough and granular; discs large, immersed
  • Spores 2030m long, thick-walled.
