RM MMDMD0 - Common Greenshield Lichen (Flavoparmelia caperata), a foliose lichen, growing on a tree trunk in the UK. It is surmised that they contribute to shielding green algae from excessive sunlight exposure since bright sun is inimical to photosynthesis, the source of all lichen energy. The quality of precipitated rainwater is why lichens are useful for environmental monitoring as their growth correlates to air quality. Urban areas tend to be nearly devoid of
