This is a crustose species with a thick, ochre-grey, scurfy, C+ orange thallus and occasional brown-black discs with a wavy edge. It grows on siliceous rock by the sea. L. asema with more rounded discs is similar, but has a granular, more coherent, thallus. L. meiococca is entirely scurfy, fading in colour to grey in shaded conditions. In Ireland, it occurs mainly along the north and west coasts.

Key characteristics

  • Thallus C+ orange, ochre to grey, finely granular-scurfy; discs rare, flexuose
  • On siliceous rocks, coastal.
