Xanthoparmelia chlorochroa, commonly known as the tumbleweed shield lichen, or ground lichen,[1] is a foliose lichen in the Parmeliaceae family. It is not fixed to a substrate, and blows around in the wind from location to location.[1] It is used as a dye by Navajo rug weavers.[1]

Habitat and range

This lichen is abundant on the High Plains of Wyoming.[2]

Ecological interactions

It has been implicated in the poisoning of domestic sheep and cattle in Wyoming during the 1930s.[2][3] It has also been implicated in the poisonning of elk in 2004.[3] It has been used as a remedy for impetigo by the Navajo.[4]
