The bright yellow thallus of this lichen of natural, nutrient-enriched siliceous rocks is best compared with its cosmopolitan relative C. vitellina (described elsewhere). In C. coralliza, the thallus is a continuously cracked crust of small, spherical-coralloid granules. Discs are rare. Low granitic boulders and the tops of standing stones are the favoured habitats due to their high use as bird-perching sites. It is generally scattered throughout Ireland.

Key characteristics

  • Not an urban species preferring hard, acid, nutrient-splattered rocks in open situations
  • The thick, cracked, densely granular thallus bright golden yellow in colour, is typical.
