description Flavoparmelia caperata Overview
Flavoparmelia caperata, commonly called the green shield lichen, is a foliose lichen with broad, rounded lobes and a yellow-green to gray-green upper surface. It commonly grows on the bark and branches of trees, and it can also occur on wood or rock. The wrinkled lobes and shield-like outline make it recognizable in many temperate regions as an epiphytic foliose lichen.
help Flavoparmelia caperata FAQ
Why is Flavoparmelia caperata called green shield lichen?
The name refers to its broad, rounded foliose lobes and yellow-green to gray-green color. Its wrinkled, shield-like thallus often forms a noticeable patch on bark.
Where does Flavoparmelia caperata grow?
It commonly grows on the bark and branches of trees, but it can also occur on wood or rock. The species is therefore more flexible about substrate than a lichen restricted to exposed siliceous rock.
What shape are the lobes of Flavoparmelia caperata?
The lobes are broad and rounded rather than narrow, hair-like, or cylindrical. Their wrinkled surface and greenish coloration help distinguish this foliose species from fruticose lichens.
Is Flavoparmelia caperata a foliose lichen?
Yes, it is foliose, with leafy lobes that spread across the substrate. Its thallus is structurally different from the crustose body of Placopsis gelida and the filamentous body of Ephebe lanata.
