Habitat Summary for element in Georgia: Dry woodlands to mesic forests
Whitish continuous, lumpy thallus; apothecia with dark-brown disks often lightly dusted with pruina, & variably prominent thalline rims; MICROSCOPY: brown, 2-celled spores ellipsoid, with angular lumina; CHEMISTRY: thallus K+ yellow (atranorin, crystals of which can be seen in medulla under magnification); FIELD ID possible with much experience, but best confirmed in lab with dissection, given possible confusion with other crusts sporting thalline-rimmed disks (e.g., Lecanora, Tephromela, etc.)
Other Rinodina on bark have green or brown thalli, except pale R. adirondackii, a rare montane species with PD+ orange thallus & spores with rounded lumina
