NOT Physcia

I cannot make out what this is - the photograph needs to be in better focus.

However, it is definitely a crustose species and, frankly, not at all like Physcia.

Note added in edit: this might well be Haematomma ochroleucum, which likes gravestones. Unusually green, but maybe there are algal cells on the surface.
