Big fungus

Walking and litter picking in Kinnoull Hill, on our first time there for a few weeks. I don't think I would have noticed this large fungus if I hadn't been looking into the trees for rubbish.

It's a bit like the description for Clouded Agaric, but larger and on its own, not a circle. So I don't know its name.

This is three images from my phone, focus stacked. I might be getting better at it.
