poisonous or not

I know.  Disgusting pictures of mushrooms.  But they are growing in my yard!!!  All of them.  Including that beautiful red one.  I wish I knew if they were poisonous or not.  My guess is they are, so I promise I won't be experimenting.  They are growing at unprecedented speed and I can't keep up with them.  Might have to resort to putting money into the lawn.  We wanted to avoid that since we only have one more summer here.
However, if they are rare and expensive and tasty, I would love to cook them up.  I won't, I won't.
