Just added two photos of the reticulated stipe. Double checked BRB, and found this species to be the best match with chem. results other than FeSO4. Don’t know why, but it did “erase” the blue stains to show the original yellow trama color. Thanks for your advice.

Chemical tests aside, what other boletes can this be growing so early in the season in hemlock-dominated woods? I’ve collected But. brunneus at Nescopeck S.P. at the end of June two years ago, and that was the trailing end of their flourish. I think the gestalt morphology of your collection is consistent with a Butter Bolete.

Just reread my notes and noticed that I didn’t add FeSO4 to the chemical change of the trama. With this additional info, the chem. tests don’t seem to match the expected result for B. brunneus.
Nothing found in that spot today. If you still want photos of the reticulations I’ll see if I can post some photos of them if they are still visible. If not, perhaps wetting them will help.

Okay, Phil

Can you get a better shot of the reticulation?

Thanks again Igor

I’ll be going back there sometime tomorrow, and with some luck perhaps I’ll find another in better condition.

Thanks, Phil

Let’s wait for more consensus on the But. brunneus proposal. It’s a very good edible, so you might want to hold on to it. :-)

Thanks Igor

Can dry and mail it to you if so desired.

Interesting collection, Phil

It’s a shame this young bolete is not in tip-top shape.
I don’t recognize this taxon as anything I’ve seen before.
IMO, this is doesn’t belong either in Baorangia or Lanmaoa.
