I cling at straws.  Obviously you would have found it in the books you
consulted, but could you have a Strobilomyces?  Some of the features fit,
maybe the warts, the wavy margin (if by that you mean veil remnants).
Most of the features don't fit, however, so this is probably off the mark.
The color of the cap does not sound like that of Strobilomyces, either
floccopus or confusus,  although Smith & Thiers (Boletes of Mich.) say the
color in the  former goes from black to "mummy-brown", whatever that is.
In both species, the pores change from white to gray with age, not cream
colored.   The pores are not decurrent (but adnate-subdecurrent in small
specimens [S&T]).  Nor is the stipe beige.   No "root."  Is there hope  for
the warts, which in S. confusus are:  "very acute erect spines which are
denser towards the center..." (S&T)?

In conclusion, you have made an interesting find.  Let us know what you
find out.
