In this case, though, my rose is not a rose but a lichen that I thought looked a lot like the outline of a rose – my warped imagination perhaps, but pretty nonetheless. I spotted this on a gravestone during a wander around the graveyard that surrounds St Augustine’s Church here in Penarth. I presume it’s one of the Caloplaca species of lichen, possibly Caloplaca decipiens, but many of this species seem to look alike and I am not at all skilled in identifying lichens.
