Xanthoria parietina, the golden shield lichen, is a conspicuous yellow foliose lichen
This lichen is formed of two organisms living together symbiotically:
Xanthoria parietina is found in sunny, exposed places that are rich in nitrogen
Xanthoria parietina is tolerant of high levels of nitrogen especially ammonia and is common on trees and buildings near farmland.
Xanthoria parietina can be used as a monitor for nitrogen in the atmosphere.

The yellow foliose lichen - Xanthoria parietina
Xanthoria parietina forms a conspicuous yellow band on sea cliffs where there are plenty of seabirds to provide the nitrogen that it loves.
Xanthoria parietina is formed of a fungus (forming the body) and a green chlorococcoid alga (which provides the nutrients for the fungus).
