Hi, I was hoping someone could help me out with a lichen identification. I found this guy almost completely dried up in the devil's garden by Klamath Falls, pretty dry and open habitat, growing on soil+moss under shelter of some Arbuscula. The rhizine-covered veins (these pictures are when wetted) point to Peltigera rufescens, but the photobiont is green, unless I'm very mistaken, with no cephalodia that I can find. Any help is appreciated.
According to the Lichens of North America, Peltigera rufescens should have a tomentose (woolly) upper surface. Doesn't seem to be the case here. Peltigera ponojensis grows in similar habitats, but shouldn't have a shiny upper surface. Assuming the photobiont is green, I'm not having success with the key in the book. Closest match is Peltigera leucophlebia - and yours doesn't have any freckles.
