Observation 22214: Peltigera aphthosa (L.) Willd.
When: 2009-06-12
Herbarium specimen reported

Notes: Still working on these two obnoxious species… I found both on the same embankment. (And if the mosquitoes had allowed it I might have even photographed both side-by-side!) This was significantly smooth, thicker, with lighter, broader cephalodia, distinctly in-rolled margin (Trevor’s “silver lining”). It also had continuous cortex on back of the apothecia (ruling out P. leucophlebia for sure, as it never has this character). And it had interesting broad indistinct but contrastive veins with the apparently typical small brushy rhizines.
