Are all of these the same. Xanthoconium separans. I wonder about the six images of two individuals that come after my first image. I also wonder about the last three images of a different individual.

growing under Pinus strobus (white pine) but there were also Quercus rubra (red oak) growing around as well as other hardwoods.
I had thought maybe B. variipes which I found growing in the general area but the cap lacked the velvety cap of B. variipes. I have now read that it can lose the velvety cap with age but the smaller individual in question doesn’t seem that old.
Boletus atkinsonii seems pretty good except the stalk is perhaps not as strongly reticulate as it should be. Still I think it does seem close. I think this is likely the best bet for these individuals.
Thanks for the help with this.
Did you find these under conifers or hardwoods?
these clearly belong to the Boletus edulis group, which incidently includes X. separans. Your bolete(s) in question could be either B. variipes or B. atkinsonii — check MushroomExpert.com for descriptions. Also, I suggest you “arm” yourself with ammonia and KOH — sometimes they settle an argument when it comes to IDing boletes.
I now think that the individual in photo 2,3,4, and 5 and the individual in photo 6 and 7 are perhaps the same species. I also don’t think either is Xanthoconium separans but I am having a hard time trying to place them. They both have a stem with some reticulation (more so towards the apex of the stem). Does anyone have any thoughts. The taste is pleasant. How about Boletus hortonii (but I believe this is supposed to have a smooth stem).
Thanks for your thoughts. I didn’t do an ammonia/KOH test for these.
Looks like all are X. separans in the top picture. I’m pretty sure the last 3 images are that of X. separans, too. The large stipeless cap in pics Nos. 2,3,4 could be X. separans (the cap color + corrugated surface are in line with what may be expected of a old specimen of X. separans); the stipe itself (image #5) may have some washed out lilac or pinkish tones, but it looks kind of brownish to me though. In my opinion, the young basidiocarp (images #6,7) is not X. separans — there is something not right about the colors, reticulation and cap texture; but I could be wrong for it’s only a picture. By the way, did any of these pass the ammonia/KOH test for X. separans?
