Probably Diploicia canescens

I am holding off posting an ID for this (though that doesn't stop anyone else). From the thumbnail I had no doubts, but viewing the photo at highest resolution ... well ... it is odd.

The main thallus is less appressed to the substrate than usual, seems not to have a pruinose surface, and seems to lack the characteristic soredia. There is a more typical sorediate thallus near the right edge of the photograph.

So it needs more thought. By me at least.

Diploicia canescens is a 'placodioid' species - lacks a lower cortex and is tightly bonded to the substrate as in more typical crustose species, but the margins are lobed.

Thank you

I'm likely to be going back there in a few days, and I remember precisely where it is. Is there anything I can do to help confirm an ID?

I wouldn't bother

As you will see, I have posted a definite ID. Just didn't want to rush into a rash ID before I had given it some thought. My webpage shows some of the range of variation in the species.
