is likely Caloboletus peckii. http://mushroomobserver.org/246697?q=2IWV

It has a different cap texture (almost like fine suede leather), which fades graying in age, different reticulation and a reported bitter taste.

There is a lot of uncertainty surrounding the identification of this once common species. I believe it was incorrectly placed into Butyriboletus.

This seemed like a good match according to BRB.

Is this the preferred name for Caloboletus peckii? For some reason there seems to be no record of Butyriboletus peckii on Mycobank. Caloboletus peckii is listed as the current name.

It was pretty exciting when I realized what it might be.

As described in NA Boletes, peckii looks like a good possibility.
