I had not collected this. But the description matches.

From Field Guide… “With whitebark and lodgepole pine, true fir, mountain hemlock at relatively high elevations to the tree line.”

J. Trappe’s photo in Field Guide is a close match to yours.

This Gastroboletus does not change color.

Yes, Daniel

it probably does.

And Debbie, you should read the park signs more closely. See new photo. You are right that it use to be off limits, but no more.

is perhaps indicative by itself.

Isn’t that where they have that really big “no mushroom hunting” sign? ;)

I did not,

and did not make any attempt to cause it to stain. It was wet when collected, and I tried to keep it intact for shipping. By the time a decision was made, it wasn’t looking good, so it was dried whole. On the other hand, I saw no sign of staining from handling or cleaning.

Did you try slicing any?

Many Gastroboletus change color quickly when sliced.
