Depending on where you are it might make sense to buy a bolete specific id book - i have "Boletes of North America". It is comprehensive and specific to the continent. But even this book is circumspect about always getting a clear identification with boletes.

However it sounds like you have a bead on your local bolete options. Personally, i've never encountered a clear B.edulis-like bolete in and around NYC - only in eastern Europe. However several sources indicate they do exist in north america. I'll keep looking - meanwhile i'm going to update the post as reading over the bolete book has revealed at least one other intensely gastrically poisonous bolete species, B.sensibilis.
