Xanthoparmelia lecanorica is a foliose lichen that belongs to the genus Xanthoparmelia. It is noted for being similar in appearance, and has often been misidentified as, Xanthoparmelia arida.
Xanthoparmelia lecanorica grows to around 3âÂÂ5 cm in diameter with broad yellow-green sub irregular lobes that extend 1âÂÂ2 mm wide. The underside is dark brown to black, with simple rhizines approximately 0.2-0.5 mm long.
Xanthoparmelia lecanorica is found in South Africa. At times, specimens of Xanthoparmelia arida have been misidentified in North America as Xanthoparmelia lecanorica.
Xanthoparmelia lecanorica has been recorded as containing both lecanoric and usnic acids.
