No clear detail visible

I don't think this is identifiable.

It doesn't look like a Candelariella to me. (Which, by the way, are crustose, not leprose.)

Thanks

Thanks for the clarification Alan. Is there a yellow leprose one I'm thinking of instead? Or, is it that my understanding of the definition of leprose is wrong?

Powdery

I would describe a leprose lichen is one that consists of a layer of granules, loosely held in a matrix of fungal hyphae, but with no organised fungal layer - yellow examples would include Chrysothrix, and those species of Caloplaca formerly placed in a separate genus, Leproplaca. However, there is every gradation from purely granular to a well organised crust.

But is what is visible in the photograph leprose? I am not sure it is. There might be some out of focus lobes there. I wouldn't rule out it being a Xanthoria of some sort. But as we cannot see any detail, I don't think it is possible to tell.

Thanks.

Ah, thanks Alan, very helpful. I think I might have been thinking of Caloplaca citrina.

I agree, insufficient detail really. Hachidori, any chance you've got a clearer shot?

Doh!

Unfortunatley I was being 'artistic' and thought a shallow depth of field would look pretty. Going to the site tomorrow, so will take a 'proper' photo then! ;-)
