Letharia is an eye catching genus of fruticose[1] lichen belonging to the suborder Lecanorineae,[2] distributed ubiquitously on all continents except Antarctica.

There were historically two species of Letharia: L. vulpina and L. columbiana.[3]

Recent molecular sequence studies published in 2016 confirm at least 6 species in Western North America alone, with more expected to be confirmed using similar methods in other parts of the world.[4]

Here, Letharia vulpina is visualized using a infrared spectrometry. The chlorophyll in the Fir needles reflects near infrared wavelengths of light, but the green vulpinic acid of the wolf lichen does not.
