Leightonking22 Posted November 30, 2021 Report Share Posted November 30, 2021 Found this on the Central Coast of California among Monterey Pine trees. No immediate bruising on cutting the stem, the flesh in the stem is white. I was told bicolor Bolete from a different group, I would like a second opinion if anyone can weigh in.

rbenn Posted November 30, 2021 Report Share Posted November 30, 2021 Is the bottom one the same as the top two? I can see the reticulation on the stem for the top two but not the bottom one. This does not look like bi-color to me. Cap is browner than I'd expect for that. Quote Link to comment Share on other sites More sharing options...
Leightonking22 Posted November 30, 2021 Author Report Share Posted November 30, 2021 It is the same mushroom. the bottom pic was taken in full sunlight as opposed to the shade that I took the first two in. And that's exactly what I thought when researching, doesn't look a lot like bicolor. That being said, do you have any idea what this may be?

Dave W Posted December 1, 2021 Report Share Posted December 1, 2021 Definitely not any of the species or varieties in the Baorangia bicolor group (the "Bicolor Bolete"). The B. bicolor types are eastern NA mushrooms. They associate mainly with eastern NA oaks (and possibly sometimes spread to hemlock or white pine, also eastern NA trees). B. bicolor has a stem that is red (or reddish) on the lower 1/2-3/4 and yellow above. The flesh inside the stem is yellow. I don't know the boletes of CA. The west coast species are mostly (all?) different from those that are found east of the Rockies. My best guess for this is Aureoboletus flaviporus.

Leightonking22 Posted December 1, 2021 Author Report Share Posted December 1, 2021 Your guess seems a lot more accurate than the recommendation I got from the Facebook identification page! I will look into that and see if I can find a more local forager to confirm. Thanks for the help! Quote Link to comment Share on other sites More sharing options...
Dave W Posted December 1, 2021 Report Share Posted December 1, 2021 Here are 7 pages of Mushroom Observation posts where A. flaviporus is proposed as an ID (some more confident than others as evidenced by the %). https://mushroomobserver.org/observer/observation_search?pattern=Aureoboletus+flaviporus Many show mushrooms with bright yellow pore surface, which is what appears to be typically reported for this species. But, there are a few where the pore surface is a bit duller, kinda like the ones seen in this discussion. Where I live here in PA we have two Aureoboletus species that are common, A. innixus and A. auriporus, each of which have vividly golden-yellow pores. With post-mature specimens the color may fade, as seen in https://mushroomobserver.org/213886?q=1l7LT . (To a lesser extent we also get A. roxanae, which has pore color somewhat more variable). The mushroom seen in this discussion reminded me of A. projectellus, a species common in the Pine Barrens of NJ https://mushroomobserver.org/257754?q=1l7LT . The resemblance was what prompted me to check "Aureoporus" at https://www.mykoweb.com/CAF/species_index.html#1_18 . Quote Link to comment Share on other sites More sharing options...
