Fungus

A very busy work day.  Not much else.  A lovely, but short pre-work walk on a crisp, cold and frosty morning, followed by a day at the laptop.  I popped out to grab some fresh air in the late afternoon before it got dark.
BB had to go for a walk as part of his PE challenges this week, so he accompanied me for a walk after tea – in the rain. 
I spotted this fungus on an old tree trunk.
