Boletes that have been causing problems in the northeast are Boletus huronensis (which is listed as edible in Bessette, Roody, Bessette) huronensis is a bad one, causing bad gastronomical distress. One person I know keyed it out to “Butter Bolete” using Arora’s MD (which it keys really nicely too) and was throwing up for almost 30 hours, another case I know about was somebody who thought it was edulis and took a quarter size bite raw and had over 12 hours of diarrhea and vomiting. This being said, some people can and do eat this mushroom.
