I don’t recall ever having seen this type here in NE PA. Reminds me a bit of B. speciosus var. brunneus that I find in a few different spots around here, except the cap on roseopurpureus is vivid red and the stipe is almost completely yellow. I see in the Big Bolete Book that roseopurpureus also has sour tasting context, which differs from the mild tasting speciosus types.

in this mushroom in my experience Renee…I find it most summers but it’s not common but the pore mouths and the flesh blue consistently.

Hello Bill, I found this bolete too in Quebec last summer. In Bessette’s description there is no mention of the blueing of the cap. I can see that feature on your cap. Have you noticed if the color change is constant?
