(This is the only attribute for this mushroom that was not lining up in the description). The pores were small, and VERY short especially for a mature large specimen. They were depressed near the apex, which is described in Bessette.
The stipe was hefty blued when bruised and lacked reticulation. It was 2/3 yellow with red base.

You should try to post again. There is already an OB for B. carminipes on MO that you had commented on earlier this month.
The Bessette’s book does mention that Boletus pallidoroseus has an “odor reminiscent of beef bouillon or in age of rotted meat”.
Damon, I see you are using Ferric Chloride instead of Ferric Sulfate. I don’t know if you can assume that the reactions will be identical.

since there are no B carminipes on MO, can you please post your collection.

I just got what I’m 95% sure is Boletus carminipes this past Sunday in CT and found a large patch in my yard today. It’s not this mushroom, this fits B. pallidoroseus_ well.

smell alone, then this would be a dead ringer for pallidoroseus. But the flash from stained blue back to tan with KOH would seem a definable characteristic as well. Next time you find this one, check out the KOH reaction to the blued pores. If it does the same, lets change this OB

Maybe we walk over these a lot thinking they might be sensiblis…who knows..
The Macro characters would def be
1. Short Pores
2. Specific Red Carmine Stipe.
3. Depressed pores in mature specimens.

The smell was really powerful, so dont know if that is something subjective, or could ebb and flow, but I would perk up for that. I know that Bessette says no distinct odor, so that goes against this Bolete, but the chemical tests were right on and not for say a sensibilis or bi color type mushroom.

Your input?

Do you have any details on this?

I don’t find this in CT but it seems like I should. What are the good macro characters for this ID?
