With Peltigera it is always, the OTHER ONE!

Tough one

I keep going back and forth between canina and membranacea. It looks more tomentose than usual for membranacea, and the overall shape looks more like canina than membranacea, too. But the rhizines (at least the ones we can see) are completely separate and tomentose, and the veins are so distinct and white. Also note that it is growing on a mossy limb, an odd location for Peltigera. Maybe there’s something about this habitat that’s causing it to look “wrong”. Usually only P. collina will grow in such places. (But it’s clearly not that species!)

is another option. The margins of main lobes generally down-turned towards the tips together with the rhizines point in this direction. Maybe Jason can give an help here.
