This lichen, which is common everywhere on buildings, pavements, walls and concrete, forms small, scurfy, chalky-white to grey-white, amoebae-shaped spots and blotches, about the size of a child’s fingernail. The discs are crowded with thick, white margins and pale pink to green centres that are variably frosted over as if breathed on. Calcareous rock: it is abundant on churches, limestone memorials, garden patios and the like.

Key characteristics

  • Very small, scattered white patches, congested in the centre on walls, concrete and limestone buildings
  • Discs often distorted, with slightly frosted, pink to greenish centres and white margins.
