Yellow fungus

Went for a walk at Cliveden with my new camera. We were there relatively early so it wasn't too crowded. We went along the river and then up the long flight of steps up to the main house. Several of the trees on the edge of the steps had these bright yellow bracket fungi growing on them. 
Stopped for a coffee and a cheese scone as a band of rain came over. Luckily it didn't last and we were able to continue our walk without getting soaked.
