Xanthoparmelia (rock-shield lichen) is a genus of foliose lichen in the Parmeliaceae family.Xanthoparmelia is synonymous with Almbornia, Neofuscelia, Chondropsis, Namakwa, Paraparmelia, and Xanthomaculina. This family of lichen is commonly found on the mid-east coast of the United States.
The name means 'golden yellow parmelia'. The photobiont (photosynthetic partner) is trebouxioid (a genus of algae).
Distinguishing between species involves how much they are attached to the substrate, whether or not isidia are present, lower surface color, and chemical spot tests. All members of the genus react to spot test as K-, KC+ yellow, with medulla reaction varying from species to species.
