I would love to help you on this one. However, it is so difficult to confirm which is which when it comes to Boletes. I have found so many different kinds and have always been leery in trying them. Most often they are \"Bitter Boletes\" of some sort. I believe non-poisonous but very bitter. I believe it is very rare to find a King in our neck of the Eastern part of the USA. The only Bolete I eat is the \"Old Man of the Woods\". Yes it is a Bolete.
Hopefully someone can help you ID this but I would suspect it to be a bitter bolete. Taste a little piece of it and then spit it out. Does it taste bitter or peppery?
Also the stem on a King is typically much bulbyier and stocky
So I am leaning strongly against this being a King Bolete IMHO.
