1. (countable, uncountable) Unprocessed mosses and lichens found growing on trees, often used commercially in fragrances.
   • There are but few plants, also , (such as perhaps, the Yew, Savine, and most treemosses, ) which do not serve for the abode and support of known Insects. 1825, Johann Friedrich Blumenbach, Richard Thomas Gore, A Manual of the Elements of Natural History, page 175:
   • Treemoss products are generally used to “cut” true oakmoss in order to reduce the cost. 2017, Steffen Arctander, Perfume and Flavor Materials of Natural Origin, page 451:
   • The principal constituents of treemoss are lichen acids, some of which are atranorin, furfuracinic acid and chloroatranorin (Guenther, 1952). 2013, D. L. J. Opdyke, Monographs on Fragrance Raw Materials, page 711:
   • Of chemicals relevant for sensitization, a typical industrial treemoss absolute oil (which is also an extract) may contain approximately 0.36% atranol, 0.22% chloratranol and 5-6% dehydroabietic acid and other resin acids (including the allergenic 7-oxodehydroabietic acid), but undetectable levels of atranorin and chloroatranorin, as these are easily degraded into atranol and chloroatranol (20). 2021, Anton C. de Groot, Monographs in Contact Allergy, page 268:
