Guessing it is B. rubricitrinus

So, Logan, we’re going with B. rubricitrinus as our best guess.

Very little reticulation …

… and from what I can remember, there wasn’t anything special about the flavor.

Thank you for the suggestions, Arleen. It wasn’t quite a shot in the dark, but it was dimly lit for sure.

Not B. pseudosensibilis

Logan – is there reticulation anywhere on the stalk? Is the odor of the flesh unremarkable, or distinctive like curry or fenugreek? Did you happen to taste the cap flesh? If so, was it acidic or not? These are important characteristics tht would help narrow down an ID. It is not B. pseudosensibilis because, among other things, the cap is not dull rusty brown to dull reddish brown. It very well could be Lanmaoa carminipes, or B. rubricitrinus, or B. sensibilis. Nice photos!

Thank you …

… for a thoughtful and thorough reply. These are fairly common around here, so I shouldn’t have trouble tracking one down for the ammonia test.

Thanks for commenting and challenging my vote.
Your mushroom belongs to a rather difficult section of boleti — the bicolor type with varying degree of bluing. The essentially yellow stipe does suggest B. pseudosensibilis, but it’s not infused with red. The burgundy/purplish stains on the bottom half of the stipe are rather unusual — they appear be caused by injury rather than part of the original color scheme. Also, the cap is too pink for B. psedosensibilis, but this could be an artifact of your camera and lighting conditions.
There are many cryptic species in the bicolor/pseudosensibilis/sensibilis cluster lurking in the south-eastern part of the country, and I suspect it could be something else that is unique to your geography. Also, I don’t know if B. pseudosensibilis occurs so far south.

If you encounter these boletes again, drop ammonia on cap — see www.mushroomexpert.com/boletus_pseudosensibilis.html

I’m not second-guessing your judgment. In fact, I’m quite grateful for it. But do you have a better candidate (or two) in mind?
