This is the European real B.aereus which now is re-named in America as independent species B.regenius and B.rexvernis respectively if I’m not totally wrong.

variety in all features of boletes is a hallmark, and there are few easy ways to tell which species you have, certainly not by location or obviousness of reticulation (or, apparently, cap color). Cap texture and macrochemical tests are what he used.
And no doubt, since I am only seeing selected photos online, the photogs chose ones that illustrated a feature that they wished to emphasize or deemphasize, so a photo survey is hardly conclusive of the spectrum in the field.
Life is complicated and we humans are error prone. My apologies for getting a bit huffy over this ID. I am now stepping awaaaaaaaay from my computer…
show prominant reticulations all down the stipe, not the more subtle apical reticulations in regineus or aereus. at any rate, this is all bluster at this point, since Gerhard collected the mushroom and is the ultimate authority for this sighting.
Glad after much back and forth he can finally keep the name he originally chose.
The specimen, of course, is long gone, and I hope that it was as delicious as our usual taxonomic debates.
>what I am NOT seeing in Gerhard’s photo is the strong stipe
>reticulation that should be obvious in reticulatis.
Debbie, the stipe reticulation in reticulatus should not necessarily
be obvious. No idea how you arrived at that conclusion – no European
source that I have access to (quite a few, btw) emphasizes that
characteristic. On the contrary, B. reticulatus/aestivalis has a
finely reticulated stipe, which is not particularly apparent unless
you look very closely. In fact, both aereus and reticulatus have
reticulated stipes, not visible on the photo. I wouldn’t base judgment
Gerhard wrote to me privately why he believes that this is B. aereus
and I accept that. He has other observations that we’re unaware off. I
only commented on the photo and colors. Another thing is that
sometimes we need to remark onsome observations that they’re not
entirely typical for the species they are supposed to represent.
scroll thru a couple of pages of google images to see more examples of pale-capped aereus; what I am NOT seeing in Gerhard’s photo is the strong stipe reticulation that should be obvious in reticulatis.
Boletus aereus, as I saw some at the market, as well as in that poor
photo of mine (in-situ), has a distinctly dark cap. In my ancestral
area (Bulgaria) they call it the Bronze Bolete. It is much firmer than
the B. reticulatus. I promise to snap some better photos this year.
because every microscopic character is similar, even the structure of the cap cuticle and their habitats, and I can’t find any other differences than the colours. That makes me wonder if I have seen aereus without knowing it (!)
My European experience with Boletes is rather slim, but Gerhard, I do
see something much more resembling the Boletus reticulatus/aestivalis
concept than Boletus aereus, which has a much darker cap.
Admittedly, not the best photos that I’ve ever made, but here are my
European collections of these:
Hopefully this year will get more European Boletus photos..
No sense is having the pendulum swing too far the other way now, calling those European collections by the new and inappropriate American names. Or is this just a case of wild west justice?? ;)
I wonder how we can see the difference between Boletus reticulatus and a pale Boletus aereus?
