Oak moss (scientific name Evernia prunastri) is a lichen species and can be found growing naturally in several hilly temperate forests all over the northern hemisphere, counting various regions of Spain, France, Portugal, and North America in addition to several parts of Central Europe. This lichen species mainly grows on the branches and trunks of oak trees and, hence, the name. Oak moss is also found growing on the bark of various deciduous trees as well as conifers like pine and fir. The thalli (singular, thallus) of oak moss that grow on the bark of the tree are small (measuring anything between 3 cm and 4 cm long) and luxuriant. Precisely speaking, the thallus of oak moss has a flat and strap-like appearance. These thalli are much branched and bear resemblance to the form of antlers of deer. Oak moss is found in a variety of colors - ranging from green to greenish white when they are dry. On the other hand, the color of wet oak moss varies from olive green to yellowish-green. Oak moss thalli have a rough surface when they are dry. The texture of wet oak moss is somewhat rubbery. In present times, oak moss thalli are extensively used in making perfumes.
