Boletus is a pore/tube mushroom. Pore/tube and polypore mushrooms have
no gills. Your taxonomy, though not unknown, is still the opposite of
apodictic. You could as well say that there is only one mushroom in
the whole wide world: Agaricus bisporus and its varieties. And you
would say, no doubt, that morels and truffles are actually yeasts, as
they are in the same subphylum as baker's yeast. Even though the term
"mushroom" has no technical basis, I would say that 99% of mycologists
would disagree with you regardless. They call Boletaceae mushrooms. I
could easily post a hundred references. Here are just a few, found in
about five minutes:

As to the "not mushroom bolete" in canned and dried mushroom soup, you
must be living in a world all of your own. A few brands include some
bolete, most do not, for the simple fact that Boletus edulis is very
expensive. It is not cultivated on any significant scale, let alone a
viable commercial one.
