Observation 174591: Boletus bicolor Peck
When: 2014-08-19
No herbarium specimen

Notes: This was a mature specimen in really great shape. All of my observations recorded below were taken after the mushroom was refrigerated for two days, then brought back to room temperature over about 1.5 hrs.

There was no distinctive odor from the mushroom.

The tube layer is relatively thin, in relationship to the pileus context.

The pores stained blue-green, relatively slowly/incompletely.

Stem did not bruise, even though it seemed to have some dark stains on it from earlier. This may have been the result of exposure to other mushrooms in the bag, including a lactarius.

The cut flesh did not stain blue in any significant way. The cut flesh had a few hints of blue, especially in the stipe, but these may have been from the knife, and in any case, they weren’t as prominent as what I would expect in B. sensibilis.

The second last picture was taken about 15 mins after I sliced the mushrooms. You may be able to tell that some of the bluing on the pores had disappeared at this point.

The last picture is the mushroom in the pan. Since this is my first time experimenting with this mushroom, I tasted the cooked product but didn’t swallow it. It was delicious. I will probably freeze it for another day, after it has been posted to Mushroom observer for a while, and when I don’t have other mushrooms in my belly that could potentially confuse any symptoms! But I am quite confident this is bicolor and not sensibilis.
