I have some huge, I mean 3 times the size of a football, mushroom looking fungus in a field near me. They are pretty dense in nettles or else I would have taken a photo of them. They are really white fleshed, in fact they look just like oversized mushrooms you would buy in the supermarket to add to your spag bol!!

Not that I am stupid enough to go picking them but does anyone know, without the photos, what type of mushroom are they?
