In my youth I worked at the University of Washington and had occasion to meet/work with Dr. Art Kruckeberg (a local botanist who has authored several books and has a native garden he opens up to the public a couple times a year, very very nice man). Anyway, back about 40 years, he had a giant oversized notebook of photo slides of native mushrooms. I was amazed at the sheer volume of them and at such diversity. I remember thinking at the time one would have to be very knowledgeable about fungi to safely ingest them. I'm OK with the morelles, but that's about it for my shroom gathering.
