description Evernia prunastri Overview
Known as oakmoss, Evernia prunastri grows as gray-green, bushy tufts on the bark and branches of trees, especially in temperate woodland. Despite the common name, it is a lichen rather than a moss: its body is formed by a fungus living with photosynthetic partners. Its branching, fruticose form separates it from lichens that lie against bark as thin crusts or broad, leaf-like patches. The species also has a long history in perfumery.
Extracts provide odor compounds that contribute an earthy, woody character to fragrance compositions, linking a woodland organism with a familiar manufactured material. It is relevant both to people studying tree-dwelling lichens and to those exploring the natural origins of perfume ingredients. The name reflects an established use and appearance, rather than a botanical relationship with true mosses.

It grows on the bark and branches of trees, especially in temperate woodland. Despite its name, it is not restricted to oak trees.
Why is Evernia prunastri used in perfumery?
Extracts of oakmoss are valued for their earthy, woody contribution to fragrance compositions. The lichen's gray-green, bushy growth is therefore important both botanically and in traditional perfume materials.
What does oakmoss look like in nature?
It is a gray-green, bushy fruticose lichen with branching strands. Evernia prunastri is usually found attached to tree bark or branches rather than growing as a flat crust on rock.
