Oxner wrote that X. coppinsii is rather similar to X. webery, but lobes are shorter.

It grows in rather dry mixed forest at the bark of elm (Ulmus densa) and minor on maple (Acer negúndo).
Acer negundo originated from North America (moved in the past).

Looks like Xanthomendoza in particular (separated from Xanthoria several years ago). In North America, I would guess Xanthomendoza fulva.
