Clearly a hypogeous Boletaceae…immediate blue staining reaction when cut. note true pores inside the fungus…cool!

Gastroboletus turbinatus

is one of the most grossly over- and miss-applied names in western NA…

It is a Xerocomoid bolete described from Valley Park, MO with a turbinate shape, a brown cap and pale yellow pores.

Now it is applied to any red or yellow “pored”, blue staining Gastroboletus in the west…

Please photograph and collect all you find, so they can get sorted out.

this one is likey Turbinatus

after seeing several G. turbinatus, I think this one is a decent fit. I just made a collection that also has no stipe. No collection for this one.

not turbinatus…

which not only doesn’t have an enclosed peridium, but also has a much different stipe, like that shown here:

How ’bout some micrographs, Dan?

I agree that it is atypical to be completely enclosed. I chalked it up to it being immature after checking out others in the genus. 100% is a high bar for fungi.

this seems good

gastroboletus looks right. Thanks for the id. G.turbinatus looks fairly good for a fit though it is completely enclosed, and the rhizomorphs are distinctive certainly make me feel less than 100%.
