Fossilized lichens?

Lichenrock

My lab assistant/dog discovered this small rock, about the diameter of a silver dollar, seemingly thinking it was chocolate candy. It has a white mineral structure on top of it resembling lichen, but I can’t be sure. It seems that lichen is not well preserved in the fossil record.
