Recognized by sight: Thanks to Noah’s earlier ID (and Ron P. mentioned this one, too). Orange staining on stipe could be related to smearing from glandular dots.

it does look like your European X. moravicus, comparing photos…

..but we’ll need harder evidence to claim this species for N. America.

what separates xerocomus from boletus, anyway? stipe reticulation?

another epic ID process in the works!

OK Dan, looks like ya gotta collect this one for science, and do the chemical tests as well as the microscopy! inquiring minds around the world (and isn’t that an amazing thought!!?) want to know!

Sometimes the boletus upper stipe reticulation is not apparent in a photo. Don’t think that this is a Xerocomus either, but I am reserving judgement until more facts are in.

Just have to comment..

I’m not the right person to propose anything here, but this seems close to something in the section Xerocomus. It reminds of Xerocomus moravicus, but I don’t know if it occurs i USA.
Boletus edulis (and reticulatus) should have a visible pale “net” on the uppermost part of the stem.

And btw, your Boletus edulis with the orange yellow tone in the cap, doesn’t look very much like our european ones. If it’s not another species, it sure is an american variety of its own.

Maybe Boletus longicurvipes?

From what is shown, Boletus longicurvipes may be a possibility. Did the base have any noticeable amount of white mycelium?

Not Boletus nobilis

Boletus nobilis has a wrinkled cap and is close to Boletus variipes.

These always seem to be under rhododendrons.

Same as 9133

I did not notice the orange bruising until you pointed it out Debbie. I’m pretty sure this is the same kind of Bolete as those in observation 9133:

They have a tendency to come up in groups of three, and the flavor is quite good.

oops, never enlarged it! what’s with the red/orange staining?

Not Boletus edulis complex

Not sure what this one is…

never seen this myself…

but an edulis variant makes sense. this does look different than the more typical, fat bellied porcini.

Edulis variation?

Not exactly a classic looking B. edulis but something a splitter should enjoy looking at. Bill Roody in his “Mushrooms of West Virginia and the Central Appalachians” mentions Boletus edulis var. clavipes which “has a comparatively long, yellowish orange stalk”.
