What Fungi?

I have been photographing various fungi on walks for a couple of years now, but i have never known what they are.
Many times I have asked myself "can I eat it, or will it kill me?", because fungi are like that - eating them can reward you with a range of experiences from delicious, through to swift and/or painful death.
So I have enrolled on a fungus identification course running on the 14th May with Andy Overall, foraging over Hampstead Heath.
I'll keep you posted...
