OAK MOSS ~ Dye colour Champange Beige to Brown

From Wikipedia
Evernia prunastri, also known as Oak Moss, is a species of lichen. It can be found in many mountainous temperate forests throughout the Northern Hemisphere, including parts of France, Portugal, Spain, North America, and much of Central Europe. Oak moss grows primarily on the trunk and branches of oak trees, but is also commonly found on the bark of other deciduous trees and conifers such as fir and pine. The thalli of oak moss are short (3–4 cm in length) and bushy, and grow together on bark to form large clumps. Oak moss thallus is flat and strap-like. They are also highly branched, resembling the form of deer antlers. The colour of oak moss ranges from green to a greenish-white when dry, and dark olive-green to yellow-green when wet. The texture of the thalli are rough when dry and rubbery when wet. It is used extensively in modern perfumery.
