This lichen is a North American native. It is also found in South America and South Africa.
Identification: This lichen is 1½–4″ (4–10 cm) in diameter. It is yellow-green, shiny, and foliose (leaflike), with lobes 1/32–1/16″ (0.5–2 mm) wide.. Tiny, fragile reproductive structures called isidia emerge from the surface. Except for the isidia, this lichen is identical to Xanthoparmelia cumberlandia.
