Evernia

   Also found in: Dictionary/thesaurus, Wikipedia 0.01 sec.
Evernia 

the genus of lichens of the family Usneaceae. The soft bushy thallus consists of narrow cylindrical or oblate branching blades. The upper surface is greenish gray, and the lower surface is whitish. The lichens contain everninic acid, usnic acid, and other lichen acids. There are about 15 species, growing on the trunks and limbs of trees and, less commonly, in the soil. The USSR has about eight species. Some species—including the most common, Evernia prunastri—are used in the perfume and drug industries.

For most of the species, except Evernia prunastri and Platismatia glauca, the cumulative n-hexane and diethyl ether extracts did not reach a quarter of the global extraction yields and the highest quantity of compounds was extracted with methanol.
