This sort of mushroom usually sprouts up in my lawn if we have a lot of rain. This summer was a bit of a wet one, which I was happy about. I did not have to water the garden so much, water being a very expensive commodity in Switzerland. If you really want to see the interesting mushrooms in Switzerland you have to go into the forests. There are some people that collect them. They have to be examined by the official mushroom person who can tell you if they are poisonous or not.
