I am sorry These mushroom was found in one of our foray and we could not id it.
It was a mixed wood forest.
For the yellow on the context: I did not see anything yellow in live.

IG, the lack of reticulation…

at the apex is a good point against R. griseus… as well as the overall appearance of the reticulation. But the spotty yellowing of stipe/context is variable with griseus, and occasionally completely absent.

Actually, there were some L. subgranulosum that came in at NEMF, which were darker colored than what one sees in BRB. The slim straight stature was similar to the one seen here.

“Gray” is part of the notation, not a species name. It stands for Samuel Frederick Gray, a British botanist and mycologist, who created this genus some two hundred years ago.

leccinum gray is promising.
I cant find in The North American Boletes Book.
Witch book has a description. Is there a European book somewhere?
Thanks Guys
Unfortunately I don’t have the specimen And I did not taste it.

Scabers can be seen at the top of the stipe. There is no reticulation there, which means that the apparent net-like pattern/ridging below is not true reticulation. R. griseus is always prominently reticulated at the apex, and should have yellow discoloration/staining on the stipe surface that this mushroom doesn’t have.

I still think this is a leccinum with a developmental anomaly. Here is my old observation of what appears to be a gestalt Leccinum with a similar ornamentation:

This is definitely not A. subflavidus.

Guys How about Austroboletus subflavidus ???

Gestalt suggests Leccinum.

But I find it difficult to fit the stipe ornamentation in with my concept of any Leccinum species I know.

A few traits that do fit in with R. griseus… gray cap, stipe with widely spaced reticulatum, no bruising of context, tapered/pinched stipe base, dirty-whitish pores/tubes.

The overall stature of this mushroom is that of a typical leccinum. I do agree that the stipe ornamentation looks weird.

Upper stipe…

shows black dots, possible scabers. But lower 2/3 of the stipe seems to lack the dots and instead features blackish ribs/reticulation.

Reticulations of R. griseus are whitish at first, but may darken with age. If this is R. griseus, then I think weather conditions may have caused atypical maturation.
