Xanthoria parietina
Lichen I spotted on the branches of Sambucus nigra at the side of farmland. This species is known to be characteristic for intensively fertilized areas.
The water extract of X. parietina has good antiviral activity in vitro, inhibiting the replication of human parainfluenza virus type 2 (source: wikipedia.org)
