Frosty again

A later walk this morning as I stayed at home to get a (telephone) appointment with my GP. He rang back very quickly so I was only an hour or so later going out than normal.
Since the change of blood pressure meds my BP has gone up and is now high again. He has prescribed a new second tablet to see if that helps get it down again.
The shot is of frost on the large dead tree trunk that has a range of fungi on it in the park, there was still frost on much of the fungi, but this bit of the wood looked more interesting.
