Evernia esorediosa is a species of lichen in the family Parmeliaceae. It has no soralia, but many ascocarps.

In a study it has been found that its mycobiont contains hypostrepsilic acid, a dibenzofuran. It made up 3.2% of the dry weight. In its lichenized condition divaricatic acid, an orcinol depside, made up 1.9% of Evernia esorediosa's dry weight.

Distribution

Specimens have been found in Japan, Russia, the United States of America, Canada and Mongolia.
