The classic edible bolete is Boletus edulis.
It
is mainly
a European and perhaps western N.A. mushroom
that primarily grows under pines or spruce. There are
several bolete species that are frequently misnamed Boletus edulis,
but nearly all are equally delicious just the same. In
the
east, most of what we call B.
edulis is
either Boletus chippewaensis, Boletus nobilis, B. nobillissimus, B.
pinophilus,B. variipes or some other species. They
grow
under oak. All
exhibit
some white reticulation on the stem and have roughly the same bun shape cap and
swollen base, though the cap color may be pale tan rather than a rich reddish-brown. It is in the Boletaceae family of the Boletales order.
