Almost a great photo, but can't zoom. Blades are a little wider than usual, plus it looks like there's some soredia in the middle of the blade (esp. the one on the left that's projecting out to the left), plus many of the soralia on the edges are fairly continuous, as opposed to the interrupted soralia of R.. farinacea. But a pretty easy pair to mix up.
