Crustose Lichen

This Lichen was found on a Sandstone boulder in my parents garden.
I have noticed that this type of lichen favours sandstone maybe because it forms a better bond to it as opposed to brickwork in the same area which is covered in moss.

Unfortunately, photographs of crustose lichens need to be close and to show pin-sharp detail if they are to be identified. (And even then, chemical tests are often needed.)

I don't think it is possible to speculate on this. Sorry.

Perhaps you can try again?
