Two lichens on heaths and moors

[INHT]

On The Oa, Islay to be precise. I've made tentative ids but would appreciate confirmation or (more likely!) correction. Thanks, Becky.

1) Lecanora polytropa?
1a) Lecanora polytropa with Porpidia crustulata?
2)Porpidia crustulata?

I agree with the Lecanora polytropa.

I agree the other is most likely a Porpidia, but I don't do these in the field or from photographs. My preferred technique is to take a sample, put it in a packet, take it home, and promise myself that one day I shall look at it.

I suspect that your photographs are P. macrocarpa, but I am not saying you are definitely wrong.
