I think it’s time you read my discussion in obs 244148 before making any proposals that don’t have any support.

I did think about B. tenax (now in Xerocomus), an idea inspired by the reticulation pattern, but the pores of Judy’s bolete are not “xerocomoid” and of wrong color. The cap color is also not what one would expect of tenax.

Boletus illudens or B. tenax? According to Mushroom Expert, ammonia will turn the cap surface green for either of these types.

So glad you ordered this! Anxious to see it.

The book is on its way. Should have it by Monday.

You’ve surely made some interesting bolete collections that may or may not be the same species — thank you for posting them. I think I see a couple of common morphological threads your boletes, but then that’s my interpretation of the “evidence” from your pix. Naturally, having a real specimen in hand would eliminate some of the conjecture, but to my knowledge none of these are dead ringers for anything I’ve seen in the field or MO. The fact that there has been no additional feedback/proposals from other users interested in the boletes, makes me think that these would not be found in any of the field guides; however, I do support your decision to purchase a copy of Besssettes’ North American Boletes… It’s possible I may contact you for a sample of this and/or other collections later in the year.

Very best,


IG, Am I driving you crazy with the Boletaceae?

Well, I am being driven nuts by this Family. The specimens in this ob just looked very different from the previous ones. I cannot, for the life of me, figure out what signature features I am missing. Aaargh! Overnight while I was doing a spore print “something” ate a portion of two caps (yucky), but I have one halved-stem, half of the largest cap, and 3 smaller cap portions drying now. Tonight I am going to order a big fat book on the Boletes. Thanks you SO much for your patience.

I doubt this is B. variipes. Instead I think it could be the same mushroom you collected and posted in obs 208129 , obs 208130, and obs 208567. Did you preserve a specimen?
