As far as I can tell, that seems to be it. The pale color might be due to the intense winter combined with a profound drought in the area while I observed this specimen. Thank you for the help with identification.

Distinctive “clean” look

Dimelaena is one of the few genera I felt comfortable identifying in the field right from the start. There are several species in the southwest, but apparently only D. oreina is known from southeastern Arizona. This is paler/grayer than typical. It usually has a distinctly yellowish/milky cast to it (from usnic acid: KC+ gold).
