Products from Lichens
Several forms of lichen are used to produce dyes. Ochrolechia tartarea is
one example. Litmus is derived from lichens such as Roccella tinctoria, R. fucijiormis, and Lecanora tartarea. Evernia prunastri is used in making
perfume. Cladonia mitis, C. sylvatica, and Cetraria islandica are also valuable
forage for reindeer, caribou, and moose.
