I’ve been seeing this patch of lichen for several years. It is growing on the side of a gravel path, adjacent to a cotton grass bog.

It’s only this year I properly paid attention to lichens. I never thought of checking rhizines at the time, and I’m sure I never knew what rhizines were back then either!

The habitus certainly looks much more like Peltigera hymenina, in any case.

Can’t quite see what we need to see

Two important things:

Is it completely glabrous above or is it faintly tometose near the margin?

And what do the veins and rhizines look like below?

If glabrous, perhaps it’s P. hymenina. If tomentose, then surely it must be P. membranacea (but it really doesn’t look like it to me, so I hope it is glabrous! :)
