That there are a couple major papers coming out in the next couple of years which will describe a whole bunch of new species in the Peltigera polydactylon, P. canina and P. aphthosa groups. You are certainly not the first nor the last to be stumped by that genus!

(Ha, that’s one of the few places where I have had the privilege to see much better material than you! Central British Columbia is the center of diversity for the genus, and has simply spectacular specimens that would take your breath away. …And there are still times where I’m convinced it hasn’t helped at all!)

Unfortunetely, it doesn’t work with all lichens;

See the case of Peltigera where I hardly guess one!

I never doubted you

I’m just seriously impressed! Maybe if I were in your place I could learn to recognize the same subtle color and texture you see… but from where I stand in the desert half a world away, it looks like nothing short of magic.

see my observations of that genus and see the special coloration and shyning of the thallus (this is very difficult to see in photos, but if you had observed many then you will have few doubts). But now this is not only a guess, since I just observed a specimen, and it is confirmed as the same species that I found before: J. vitrispora. Maybe tomorrow I will post some photos.

It’s awesome that you can even guess at a Jullela before microscopy!
