Description: This species occurs on the main trunk and on twigs of wayside trees that are mildly enriched with dust or similar particulate matter. It consists of small, scattered, mustard-yellow spherical granules that quickly become yellow powdery (sorediate). Search for it where branches join the main trunk, or on the narrow, spreading branches of sycamore. It may also occur in the canine zone at the base of trees.

Key Identification Features:

• The mustard-yellow colour, powdery appearance and sprinkled distribution on branches and bark should help to distinguish it
• Candelaria concolor has a distinctly scaly thallus. The other species that may occur in the same habitat, especially where dust is present, is Candelariella vitellina. This species consists of granules and is never sorediate.
