I'm guessing Amanita muscara, Bob. If that's correct, for some strange reason, it accumulates vanadium!
I believe you are correct.
"Although classified as
poisonous, reports of human deaths resulting from its ingestion are extremely rare. After
parboiling twice with water draining—which weakens its toxicity and breaks down the mushroom's psychoactive substances—it is eaten in parts of Europe, Asia, and North America.
Amanita muscaria is noted for its
hallucinogenic properties, with its main psychoactive constituents being the compounds
ibotenic acid and
muscimol. The mushroom was used as an intoxicant and
entheogen by the
peoples of Siberia, and has a religious significance in these cultures. There has been much speculation on possible traditional use of this mushroom as an intoxicant in other places such as the Middle East, Eurasia, North America, and Scandinavia." Wikipedia...
