more likely Diploicia canescens in damp state

The photograph doesn't give a near enough view, but the lichen appears to be a crust with perhaps a slightly radiate margin ('placodioid'), whereas Hypotrachyna species are foliose.

From general appearance it looks to me like Diploicia canescens, which is usually rather dazzlingly white, but which is quite green when damp. The photograph seems to show the masses of powdery soredia on the thallus surface - characteristic of this species.
