Thallus was UV+ yellow in patches

and both cortex and medulla of apothecia was C+r (best seen in section under microscope). According to Brodo & Lendemer 2012, that makes it O. arborea instead of O. androgyna. Brodo also says that the soredia are coarser in O. arborea.

Jason Hollinger identified this as O.arborea
