That's one impressive puffball.

I have to be honest, after hearing some terrible tales of sickness following people picking the wrong mushrooms, I became very wary of them. Then again, I have friends who are experts in the field (field - get it?) and have done their best to reassure me.

We have lots of chanterelles on the moor near us and I have tentatively eaten them but even they have a close relative that is pretty toxic and easily mistaken. But you have persuaded me to give puffballs a try now :)
