A walk in the woods

Is it because of all the rain and damp weather the last two months, but there are mushrooms everywhere in our garden.
I really don't dare to pick and eat them, I heard on the news that there were more cases of poisoning this year then normal (here in Belgium, don't know about the rest of Europe). My grandmother knew enough about mushrooms to use them in the kitchen, and it's a shame that I don't have that knowledge...
