When it comes to other species like Amanita phalloides (death cap) or Galerina sp. - which contain Amatoxins and resemble edibles - boiling will have no effect: You will need a liver transplant [1].
Amanita muscaria does not contain amatoxins - but it does contain muscimol and ibotenic acid, which are interesting in their own right [2].
What are examples of bolete species that are only edible if boiled? I know of a lot that are only edible if well cooked, but haven't heard of any that are only edible if specifically boiled. (I'm from New England / mid-Atlantic though, so I only know the ones around here.)
In theory, Is said that venomous boletus boiled are less toxic, but they still have unpleasant effects.
I think I need to just go take the Eagle Hill bolete class with the Bessettes one year if they keep offering it, otherwise I feel like they're just too hard to really ID beyond the handful of really easy ones.
because of this chitin, eating a mushroom raw is not very nutritious and you miss out on most of the health benefits.
