To be perfectly honest

I suspect the other observation of being P. ponojensis, too, but the visible detail is insufficient (for me) to prove the distinction. T. Goward has told me that the two species do not commonly overlap in habitat. (Of course, he promptly showed me two specimens growing side-by-side not minutes after that statement! :) So if these two observations were close to each other, looked the same, etc… then they probably are the same. I think we have enough detail in this observation to make a good case for P. ponojensis.

But let me just re-emphasize how little confidence I have! :)

Very subtle difference …

between this and the one considered in observation 98843. The only that I noticed was that the underside of this one was entirely pale, including rhizines, and the other has some dark rhizines and underside away from the margin. Apart from that they seem replica of each other, with tomentum on the upper side, upturned lobes at margin, etc.. Moreover, they were separated by 15-20 meters, with no other species of Peltigera arround.
Thanks, Jason, for being alert.

I’m still not comfortable distinguishing these two species

But this one seems more like P. ponojensis than P. rufescens based on the characters described in the name reasons.
