[3] The vegetative body, or thallus, of the lichen is foliose, and its color ranges from bright-yellow to yellow-green.

[4] Candelaria concolor has been used as in anatomical studies of lichen looking at green modules, clusters of algae and hyphae.

Electron micrograph images has revealed pockets of a protein called hydrophobin surrounding these modules.

[6] It has been postulated that these pockets allow for gas and water exchange to the algal layer of the lichen.

[8] Notable secondary metabolites created by C. concolor include: pulvinic dilactone, vulpinic acid, calycin.
