Crazy Lichen

Lots of funky looking lichens I don't even have time to look into yet. Maybe not even during 2014, althuogh I will probably acquire a field guide. This cracker though may or may not be a Peltigera species, based on photos seen elsewhere. Surrounded by Pseudoscleropodium purum here, it seems to "float" on a bed of moss, with no actual substrate (is the substrate moss?)

(The moss is, of course, Rhytidiadelpus squarrosus - thanks to SB for pointing out the error. I knew what it was, but the name got lost in translation!)
