Pseudevernia furfuracea

''Pseudevernia furfuracea'', commonly known as tree moss, is a lichenized species of fungus that grows on the bark of firs and pines. The lichen is rather sensitive to air pollution, its presence usually indicating good air conditions in the growing place. The species has numerous human uses, including use in perfume, embalming and in medicine. Large amounts of tree moss is annually processed in France for the perfume industry.
== Description ==

''Pseudevernia furfuracea'' is associated with photobionts from the green algae genus ''Trebouxia''. It reproduces asexually by isidia. The ontogeny of isidia development and its role in CO2 gas exchange in ''P. furfuracea'' has been investigated.〔Tretiach M, Crisafulli P, Pittao E, Rinino S, Roccotiello E, Modenesi P. (2005). Isidia ontogeny and its effect on the CO2 gas exchanges of the epiphytic lichen ''Pseudevernia furfuracea'' (L.) Zopf. ''Lichenologist'' 37(5): 445–462.〕
The preferred growing surfaces for ''P. furfuracea'' are the so-called "nutrient poor" bark trees, including birch, pine and spruce.
The species has two morphologically identical varieties that are distinguished by the secondary metabolites they produce: var. ''ceratea'' Zopf. produces olivetoric acid and other physodic acids, while var. ''furfuracea'' produces physodic but not olivetoric acid. Some authors (e.g., Hale 1968〔) have separated the chemotypes at the species level, designating the olivetoric acid-containing specimens as ''Pseudevernia olivetorina'', but more recent literature separates them at the varietal level.
