Flavoparmelia caperata, the common greenshield lichen, is a foliose lichen that grows on the bark of trees, and occasionally on rock.
Flavoparmelia caperata is a medium to large foliose lichen that has a very distinctive pale yellow green upper cortex when dry. The rounded lobes, measuring 3–8 mm (0.1–0.3 in) wide, usually have patches of granular soredia arising from pustules. The lobes of the thallus may be smooth, but quite often have a wrinkled appearance especially in older specimens. The lower surface is black except for a brown margin; rhizoids attached to the lower surface are black and unbranched.
The very similar Flavoparmelia baltimorensis grows mainly on rock and has globose, pustular outgrowths (somewhat similar to isidia) on the upper surface of the lobes, but does not produce granular soredia.
