Oakmoss is a lichen of the Usnea family that grows in France, Yugoslavia, Hungary, and other countries. Although moss means "moss," oakmoss is not actually moss but a symbiotic organism of fungi and algae that attaches to oak trees. Oakmoss that grows on trees is harvested and absolute is extracted by solvent extraction. It has a dusty and smoky scent, which are generally called mossy notes. It also has a resinous woody and earthy scent, making it a fairly complex fragrance. It is used as one of the woody notes that make up the oriental type, and is extremely important for chypre and fougere types. The inclusion of natural oakmoss accentuates the overall brilliance and depth of the fragrance, and creates a fantastic last note in chypre types.
