Folks,
Thanks for the additional info. I did a bit of searching about
Amanita and found (as usual!) that the world is more complicated than I had thought.
I had always thought that the
Amanita's were universally lethal. It seems that's not correct.
Amanita muscaria in particular is widely discussed as an "entheogenic agent" (read "psychedelic drug"), with reported deaths at most rare. Very different from some other
Amanita's, for example the "deathcap"
Amanita phalloides and the "destroying angel"
Amanita virosa, which also have the unfortunate feature of looking like a variety of edible species.
The lethal versions are very nasty indeed. Their toxins act specifically on liver and kidney cells, and the progress of poisoning can be succinctly described as "you feel bad, then you feel better, then you feel really bad, then you die". Liver transplant is frequently mentioned as a specific treatment.
I think I'll just leave everything remotely like this very well alone. Having had some bad experiences even with prescription drugs, I'm pretty goosey about anything more psychoactive than caffeine.
Some interesting links root at
http://en.wikipedia.org/wiki/Amanita and many others can be easily found by searching Google for
Amanita muscaria.
