It looks like the stipe…

shows some red staining. This would make a very strong case for T. sordidus. This species typically stains/bruises both red and blue, with the red typically setting in after the blue.

Yes, I looked at the other examples on MO. Didn’t see any chocolate brown pore surfaces.

Maybe I’ll find another and get more details. Thank you Daniel! Jon

Pore surface can be

white, yellow, or brownish. The key is the blue reaction on the pore surface, and the flesh blueing. Also the adnexed attachment of the pores to the stipe. The darker brown on the surface of your specimen’s pore surface may be due to climate and temperature recently. The pore surface looks a little blue to my eye.

If you type in Boletellus chrysenteroides in the Find: portion at the top of the page, you’ll see many variations.

I wonder about the ID with a dark pore surface compared to yellow like the other examples on MO.

Maybe Noah will see this and comment.

My bad, Jon.

I should have suggested Boletellus chysenteroides, not B. chysentertoides. (Where did that come from?)

Bessette and Roody say, “cracks (on cap) when present showing white to pale yellow context without red tints” and “stipe solid, often yellowish at the apex, not reticulate”. Thank you Truffle Meister Daniel!

In Arora,

keys out as Boletellus chysenterteroides. “Veil absent, cap often areolate but not fibrillose-scaley or shaggy”. I think this cap qualifies as areolate.
