A pale greyish to buffish cructose lichen, which is thin to cracked aerolate. Apothecia absent.
Found on silica-rich rock, especially outcrops that get wet and dry out fairly quickly. Locally common and widespread in the north and west.

Greyish to buffish … I like that 😀

Not an obviously photogenic subject but you’ve managed to make lichens look interesting!

Thank you, Judith 🙂 Some of the powdery, cracked cructose ones can be somewhat dull, but the foliose ones are like tiny plants. I guess there is beauty in most things if we look for it 🙂
