Lichen

Spotted this lichen flowering on the wall on the walk up from Drem this afternoon and thought it looked rather pretty.
Unfortunately, Henry the boxer wasn’t with us as he seemed to be a bit arthritic and sore this morning. It was interesting to see Molly’s reaction. She looked for him in the car when she got in and when we started walking she kept looking back as though she was expecting him to come lolloping up.
