Veronica - Wow! I am impressed as usual with your knowledge of esoteric fungal information! I found another interesting tidbit in this article that states hydrazines are in only THREE species of edible mushrooms, Agaricus bisporus, Gyromitra esculenta, and Lentinus edodes, or Shiitake. Obviously G. esculenta must at least sometimes contain either more of or a stronger toxin than the other two, since there are few if any poisonings from either of the other two edibles mentioned, at least that I can find. I am sure the key is in the preparation of the mushroom, as the article you posted stressed. Cook your shrooms and you won't die - easy, right? Every account I have read, ten at least, of poisoning by false morels indicated either improper cooking or some kind of individual sensitivity, like when one person out of several becomes severely ill or dies while the rest are unaffected.
I am mystified by the false morel dilemma and this has been a great addition to my outlook on the issue. The world of the fungus ceases to amaze me! Thanks again V. for the article and awesome information!
Greggster - smguffer, from reading his posts for the past few weeks, seems quite well-informed on his mushroom facts and I think he "knows the difference" And what does eating psilocybes have to do with false morel poisonings?!? Psilocybin is not a deadly toxin like gyromitrin, and you don't fry up psilocybes for dinner! That would be pretty nasty to eat that kind of mushroom in very much quantity, and a very different kind of experience from exposure to gyromitrin definitely!
I feel that it is a choice for the individual, as I feel about just about everything else, and there is obvious, massive contradiction and confusion about whether a false morel will hurt you or not. If you are a cautious person, it would be your choice to not eat false morels ever, but also not store bought button mushrooms or shiitakes either, since they contain similar toxins as the false morel which are also destroyed by cooking. But if you like to live life on the edge, and some may say to the fullest, you might find an experienced old timer to show you the world of the "Reds" and try one! I have yet to brave the experience, but I am intrigued and definitely fall into the latter category of a person who is willing to go against conventional wisdom and trust the knowledge of a well-seasoned forager who can assure me of the well-established safety of our meal based on his or her personal experience.
So if it is safest to NEVER eat a false morel, should we NEVER eat store bought button mushrooms or Shiitakes either?
Sorry for the giant post - great topic!
