Xanthoparmelia maricopensis (Maricopa rock-shield) is a 2-6mm wide, yellow-green foliose lichen in the Parmeliaceae family found growing on igneous rock in southwestern North American deserts.[1][2][3]:138 The thallus is tightly adnate to the substrate, with irregular somewhat shiny 1-2 mm lobes.[2] It differs from Xanthoparmelis dierythra in that it has hyposalazinic acid and the lobes are usually more narrow and more convex. The lower surface is tan and has unbranched rhizenes.[3]:138
Habitat and range
It is common in lower elevations of the Sonoran Desert in Arizona, southern California, and north and south Baja California to Chihuahua, Mexico and Sonora Mexico.[2] In Joshua Tree National Park it grows on non-calcareous rock, soil, basalt, gneiss, and monzogranite.[1]
Metabolites
The upper cortex is K-, C-, KC-, and P-. The medulla is K+ yellow to orange, C-, KC-, P+ orange.[2] The upper cortex has usnic acid as a secondary metabolite.[2] The medulla has norstictic acid and traces of hyposalazinic acid and connorstictic acid.[2]
