This variety differs from the var. albescens (described elsewhere) in lacking fine, powdery soredia. Instead it has knotted, warted or granular soredia which arise from the centre of a thickened thallus. Its distribution is scattered throughout Ireland.

Key characteristics

  • Soredia, more granular or warted in appearance than in var. albescens
  • The rare Irish species, Pertusaria polythecia, is very similar but has a different chemistry and habitat.
