Not mushroom in there!

Terrible pun, sorry!

I found this in the garden on this year's leaf mulch pile. The photo doesn't do justice to it's size. It's about 10-12 inches in diameter. I've no idea what kind it is.

In other news, it's 22 weeks since I finished work. I've enjoyed every moment of doing absolutely nothing but I've just applied to do some supply work starting after the Christmas holidays to top the savings back up a bit!
