The thallus of this granular-sorediate species forms dull-yellow green streaks or ‘flashes’ on dry acid tree bark. On conifers or dead standing pine trees the sight of it in otherwise lacklustre woodland, can be striking – like a beacon in the dark. Spot tests are negative. The related C. chrysophthalma has an immersed thallus. C. flavovirens has a scattered distribution in Ireland.
