I'd never have the nerve to try some of the stuff you do Steve, and yep am aware it's not just toadstools where mistakes can be made; I'd not know your wild parsley from its deadly relatives...

Have often wanted to try a real horse mushroom (which I sort of gather is like a field mushroom plus, on flavour as well as size)and mum has tales of her and her mum picking and using them. Don't know where they grow round here.
