for the info.

All the mushrooms in this group bruise blue on the pores and fade to reddish brown.

They all have shallow tubes and they all occur with oak and beech. Boletus bicolor, sensibilis, pseudosensibilis and pallidoroseus are best determined by these macro characters, IMHO: Whether the cut flesh blues and how quickly. Smell. Bicolor= flesh doesn’t blue (or very, very faint) and no smell. Sensibilis= flesh blues and smell of curry or fenegreek Also this one has the yellowest stipe. Pseudosensibilis= flesh blues, no smell, cap has olive tones. Pallidoroseus= blesh blues slow and weak. Smell funky like bad beef, boullion. Cap is pinkish like sensibilis can be. These are my observations from Ct but in your area things may hbe different. Of course you could always do microscopy, macro-chemical tests and measure spores. Then you’d have a better chance of getting it right. Good luck.

I’ve been finding lots of red/yellow boletes that show quite variable amounts of red on the stipes. I have not detected any type of odor with any of these boletes. Bluing of pores is quick and intense, and fades to reddish brown after about an hour. Seems similar to obs 73826.

tough to ID bicolor look-alike. This could be B. sensibilis, though I think there is too much red on the stipe. Another possibility is B. pallidoroseus, but its distribution north of NY has not been confirmed yet. Did you smell it — any odor? What about bluing of the context due to oxidation? Macrochemical tests would be useful, too.

One difference is-

that the pore surface and stem stains faster and darker blue than Boletus bicolor. B. sensibilis usually gets that solid pink rose color on the cap. I’d say it’s most likely B.sensibilis.
