On sandy soil approaching dunes. Rhizines just visible here, which I hope, alongside the downturned lobe tips, are enough to eliminate P. rufescens.
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
Thank you Alan, especially for the notes. I was under a bit of 'pressure', so didn't manage to photograph the underside. I did grab some material that has veins darkening towards the centre, which must be P. rufescens, but I can't be sure it was the material in this hurried photo.
I see Dobson (2011) gives "lobes to 1cm wide" in the key for P. rufescens/P. ponojensis, but I find that hard to swallow. The lobe I gathered spans 2cm in its dried-up state.

Yes, I agree, that is certainly a mistake in the Dobson key.
Incidentally, while I have never seen P. ponojensis, I am very suspicious of records of it from southern England. It is predominantly montane on the continent and while it has reliably been known on Ben Lawers for some time, I am not so sure about lowland records. Sensu Dobson I think is P. rufescens.
