Recognized by sight: Turns out that this population, despite having soralia, has spores far too small to be T. steppica. T. glaucopholis is the correct name, instead. (Thanks to Curtis Björk for patiently prodding me until I finally came around to the truth which was obvious to him right from the start!)
