Flavoparmelia caperata, the common greenshield lichen, is a foliose lichen that grows on the bark of trees, and occasionally on rock. It is less well known that fungi need these same nutrients for the same metabolic reasons. The photobiont for greenshield lichens is a green alga species in the genus Trebouxia, which is the most common photobiont for all lichens.
