Pictures of Letharia vulpina
Photo: Einar Timdal
On my screen, Timdal's photo below has the truest color. Thalli range from 2-10 cm long.

The other speciesin this genus (morphologically defined) has many fruiting bodies and is called Letharia columbiana (photo by Steven Sharnoff). I do not need collections of this species.
