Looking at this again ...

Very likely it is Peltigera rufescens, ID supported by the frilly margins to the lobes, but I would still need to see more to be positive. Do you have any other photographs of it that you can add to this observation?

I have a range of examples, somewhat scruffier than yours, at:

Second photo added.

Hi Alan,

I've added a second photo - hope it's more useful!

thanks

I still think it could be P. rufescens, even though the habitat is unusual. I have been assuming that the surface is tomentose but damp. However we need to see the underside, where the rhizines and veins should be distinctive.

If the surface is NOT minutely tomentose (and looking closely at the second photograph I am in increasing doubt) then it more definitely has to be left as "Peltigera sp."
