Large Toad Required - Apply At My Place!

I'd planned maybe to get to Foxley Woods today to see what that beautiful place may offer to blip, but was late up this morning and had something I needed to get done, so no time to get to Foxley - maybe Monday?
My dung heap, which had 2 types of fungi on it last Sunday (1 of which I blipped) was devoid today. It's greyish, VERY windy and cold out so I wasn't at all sure what to blip today - if it was going to be outside I just wanted to get it done a.s.ap! I decided maybe one of the developing chandeliers of bloom on the Mahonia x Charity beside the field pond would do. Just as I was checking out which bloom to snap, I glanced down and saw THIS by the bottom of the Mahonia trunk. . Blip sorted!
I measured the cap against my glasses case - over 3" wider. I later measured my glasses case at 6 and 1/2" - which makes this beauty about 10" across! Comparison of the cap against the Mahonia trunk gives a good idea of its size.
I've no idea what it is, still feel tired from a heavy, long sleep so really can't be bothered to try to ID it.
Any suggestions as to what it is most appreciated.
It would certainly make a stool for a very large toad!
