So just to confirm one more time — all the obsies discussed below, with exception of 254730, came from the same spot and are thus likely to be the same organism, i.e., what we think is the current concept of B. nobilis by DNA, but not entirely by morphology (gertrudiae is the proverbial screw that still doesn’t fit). Well, speaking of 319044, that’s the most unusual B. nobilis I have seen. Just to dot the i’s and cross the t’s, I will need to sequence this material. It would appear that the morphological current concept of gertrudiae is that of a phantom entity, though more work needs to be done for a definitive conclusion…
Thanks again for posting, Geoff!

Same area. Within a few meters of one another.

Thanks, Geoff, that’s very useful info. Yeah, I think these are probably the same.
Out of curiosity, did obs 255268 and obs 255270 (nobilis/gertudiae) come from the same spot, too? We thought they were different, but the DNA told us they are conspecific.

it just occurred to me, that this specimen was found right where I’ve found those specimens we were calling B. gertrudiae, obs 255427 about two seasons back.

good to know, Geoff… I have a hunch this could be a member of “Alloboletus”, i.e., B. separans & Co., within Boletus sect. Boletus. The cap texture and colors are most unusual for sure.

Not really,

It’s probably a half mile from that upland section I found those other dark-capped fat-bottomed beauties at.

Very nice, Geoff!

Did you happen to collect this in the same spot as obs 254730? I am not saying they are the same, but it’s the closest match I could find to any of the obsies you posted before.
