I was thinking about running a sequence on this one. It’s a curious collection!

I may have dried this.

Not only were you considerate in sending this specimen back to me, the mailing was timed to coincide with my return from vacation… most thoughtful.

Anyway, the dried mushroom has a mild flavor. The dried pore surface is yellowish-brown. I think this is not a Tylopilus.

No Problem at all,

Is the return address on your latest shipment okay to use?

Ha! I just spent the last 10 minutes looking for this! Yes, it was accidentally included along with a bunch of Amanitas I sent. Sorry for the inconvenience. Actually, I would appreciate you’re sending this back to me. I would like to test Christian’s hypothesis by tasting some of it.

No hurry on the mail-back. I’m leaving for a two-week vacation tomorrow. Do you need my address?

Interesting proposal Christian. Having seen hundreds of T. felleus each summer, perhpas when an example runs contrary to my expectation my immediate response is to not consider this species as a possibility. Cap surface looks different than what I expect for felleus. Also, although the photo appears to show a pinkish tinge on the pores, I don’t recall seeing this first-hand.

You sent us this specimen in your recent shipment as well as one other Boletus specimen with MO# 138783. I am not sure if this was by accident, would you like us to send these back to you?
