Oh so true 
Be well...
Even experts can misidentify mushrooms. Back in the 1980's in my Emergency Residency I did 1 month of Toxicology training an the Hershey Medical Center in Hershey PA. They were a regional poison control center. There was a women who was friends with our toxicologist, and she was a mushroom expert and used to pick morels. Well, she was found dead in her apartment after accidentally eating some false Morels that she had misidentified as Morels.
Bottom line is, do not pick your own mushrooms.
