A Brownie Toadstool .....

.... that's what I think of when I see one of these Fly Agaric mushrooms.

I haven't spotted many in such perfect condition. This monster is growing in the grass beside the car park at my sister's flat. There were quite a number but this one was by far the largest and hadn't been pecked at or trampled on like some of the others. It would make a good dinner plate.
