Every book I've read on mushrooms says to learn a few well, and focus on picking those. I pick chanterelles and Bear's Head fungo... The guide book I checked said that nothing else can be confused with the latter. My favorite way of cooking those is to use them instead of noodles in chicken noodle soup. 
Ink Caps are one which I recognize but have never eaten. They cause you to be sick when consumed with alcohol, one book I read said that they are used to treat alcoholism. Presumably on the same theory as your father making you smoke the entire pack when he caught you in back of the barn with a cigarette.
