Notes: The outstanding characteristic of this specimen was the rapid, bright blue bruising of the pores, flesh, and stipe. The average size of the spores was about 15.1 X 5.4 microns so that seems to include B. pulverulentus. I left some room to be overruled since the cap color seems much lighter than noted in the descriptions.

for Boletus oliveisporus also (nice photo on your Observation). The cap color is still a problem for both, however. One of the reasons I selected B. pulverulentus is that B-R-B mentions that this species blue stained pores turn brown eventually, which I did note.
Also, I checked an old species list compilation from the Texas Mycological Society that covered about 16 years. It mentions B. pulverulentus but not B. oliveisporus. That might be worth an upgrading to “Promising”!?!
to consider Boletus oliveisporus as a possible match. Unlike B. pulverulentus, it is reported to fruit in Texas, according to B-R-B that is. Check out my observation for B. oliveisporus (25138).
