Not very good pix and these were much younger specimens. I will look for them next year. I’ll be in touch so you can tell me how to preserve/send them. They stumped Greg Marley.

I think I once found this type…

in Wolcott, Vermont, month of August, many years ago… maybe 1988. Mixed woods. Pure white with reticulate stipe, like an albino version of edulis. Haven’t ever seen it since.

OK, I removed the ringers and added the stuffed pores. The entire mushroom is initially white but darkens on handling.

… the bottom two pix are not the same mushroom.

…Greg Marley is not the only one who was stumped. :-)
Thanks for volunteering to look for these next year, Kala. Preserving is simple — first, you cut this longitudinally into 1/2" slices and dry them thoroughly in a food dehydrator/jerky maker at 105-115F; then transfer them into a ziplock bag and place in a freezer for a couple of days to kill whatever bugs/eggs survived the heat. Final storage should be in a cool, dry and dark place.

Actually,

after looking at the recently added pix, I think these are in the porcini group. No idea why the stipe/reticulation darken upon handling though — this feature is not consistent with the porcini.

Very unusual

My thoughts exactly, Alan. I wouldn’t be surprised if this is a new taxon… Genus? Boletus sensu lato would probably work for now (“scientific gibberish”, anyone). :-) I am not convinced it’s a Tylopilus based on the info from the pix; besides yellow pores don’t fit with this genus.
Kala, please collect and photograph a range of fruiting bodies and preserve a specimen next time.

I don’t think is Boletus albisulphureus

Because that species is supposed to have a yellow stipe apex, and yellow reticulation over the upper half of the stipe. This has a white upper stipe apex and dark reticulation on the lower half. Also the distribution of Boletus albisulphureus is said to be more southern. Looks a bit like a Tylopilus to me, it would be interesting to see a spore print.

I don’t think Genus is in question.

Please explain why you disagree with species. I have now found that others are finding this species in Maine and their specimens agree with this one.
