Yes, they blue…

It’s not even fun anymore.

Everywhere I have been since I made that “10%” comment that blew up into major arguments… NH, MA, PA, WA, OR, and CA. they all stain blue.

And 10% is way to low of an number, it’s probably closer to 90% of all specimens at the right age; after the pores go yellowish-green but before it gets totally mush/maggoty. And most of the time it’s ONLY at the flesh on the cap at the junction of the tubes.

Does this matter? No, probably not. But…

is visible when viewed “huge”. Noah showed me this reaction on a Pa. specimen. Interesting that it is not mentioned in most descriptions.

Apparently it’s not a common occurrence though. And that’s a lot of contention going on over those boletes!

Thanks for broadening my understanding.

I do find it odd though that there is no reticulation visible on the stipe in that pic.

What was the tree population of the surrounding woods?
