is the degree of accuracy of my suggested ID, so I’m not going 100% with it. There is this thing called a “cline” and variation along a cline (north-south in this case) became readily apparent to me (and others) after nearly a decade of field work in Costa Rica.
As I have the chance, I am slowly getting Kodachromes scanned and attached to specimen records available online (http://sweetgum.nybg.org/boletineae/specimens.php) and one of those shows a specimen from NYBG with some brownish orange in the stipe. Type locality for T. balloui is Orient Pt at the eastern end of Long Island.
Osmundson & Halling (2010) suggest that T. balloui is a species complex, so there is more than one thing around the world that looks like balloui but isn’t. Todd is the expert in this group, so you might get his take on it.

Looks like the stipe can get darker..

a couple of questions about balloui (which I have seen before, but am hardly thoroughly familiar with).

Certainly the cap color is a good match. But that stipe…so seriously and completely orange, not “tinged orange,” as described in the Bessettes Bolete Book. Also, they claim that the pore surface is “never yellow” although Alan’s photo clearly shows a yellow pore surface. But looking a bit harder, I do see that the pore surface stains brown, like is described for balloui.

What say ye Roy? Do I need to modify the balloui description in the Bessette book to allow for variation? Or could this be something else?

I always find G. castaneus in association with deciduous trees.

I have found very large caps of G. castaneus… up to 6 inch diameter. But this is exceptional. Most are under 2.5 inches.
