Spot the edible one! Yes, the homely, comely, fat, Boletus Edulis at the bottom. The other two will definitely kill you, by attacking your internal organs over a period of 48 hours or so until you die of kidney/liver failure - rather like an overdose of Paracetamol.
The top one is the 'Destroying Angel', and is very pretty, like a well-made porcelain tea-cup. The middle one is the 'Death Cap', and is dangerous because it can - in a fit of over-enthusiasm - be confused with a variety of good edible ones when young, but only if you don't take care. If in doubt, leave that 'Parasol' alone until it has grown to about 12 inches in height!
