Letharia vulpina and Letharia columbiana are found in dry coniferous forests throughout Western North America, identified by their brilliant yellow green color. While their remarkable color makes them valuable for floral arrangements, commercial harvest has reduced their populations. Columbiana is distinguished from the vulpina by its brown disk-like apothecia. Both species contain vulpinic acid and are somewhat poisonous.
