Recognized by sight: Your recent batch of porcini from the mountains all look like B. rex-veris to me – more textured pinkish caps (B. regineus tends to be browner and smoother), and especially, fruiting in spring with conifers.

Awesome feedback and links! I am remembering when we had a comment fest last fall about blue and black chanterelles being contingent upon not only elevation but latitude as well. A black P.multiplex here at 5000 feet would be similar habitat and climate as sea level in Anchorage, AK. Comparatively, if True B.aureus or our B.renineus fruits through summer in your locale at around 7-10,000ft. Could it be that ours this far north at 3-5000ft. Could have all the same mycorrhizal, climate and weather patterns suitable for spring fruiting..? This season is acting almost two months ahead as well. Just found Gomphidious I find in September yesterday at 3500ft.

I love getting to the bottom of misplaced misconceptions with the advent of worldwide data basing. These new cross informational and overlapping global transects of fungi will no doubt fruit into concise beautiful, colorful and meaningful descriptions that future generations can clearly understand and use for millennia. Or, until new technology comes along and disproves all the work we pursued thus far.

Point is,
I appreciate you man! Thanks for continuing to be a science minister and spreading / creating such a “good book” of work ;-).

Fungally,

I’d never heard of the fruiting habit being a character for differentiation. Interesting.

I’d love to be able to post a photo of B. rex-veris and B. regineus side by side. But it will be tough to do, especially because as I mentioned above, they most often fruit at different seasons!

However, our recent research in Santa Cruz indicates that we might have B. rex-veris here on the coast.
I also confused them for Queens when I first saw them. Then I found younger fruitbodies and began to suspect they were not true B. regineus.

We are still not 100% sure about the ID, but the macro-morphology and first results from genetic work support identification as B. rex-veris. We have found them fruiting in the winter and spring, and so it could be possible to show them side-by-side if I get lucky and find some later Queens overlapping with some early Rex-veris in the upcoming winter.

The ones we find here are smaller than the big, lovely fruitbodies you found in these recent observations, but you can see photos showing the felty to smooth, pinkish to red caps (with a whitish bloom when young), and stipe with a dark apex in the observations here:

I have never seen spring kings this red and white exhibiting bulbous bases that plane out to almost perfect cylinders. Also had a few fruiting sideways hypogeously, an apparent macro indicator historically. I knew that reports had only been from the SouthWest but I kept so many I knew we would never be short of samples…

If you are positive I totally trust your immense knowledge and expertise kind sir. Would love a future post from either you or Mr. Noah Seigel of both B. Rex veris andB. regineus side by side for comparison to show clear macro distinctions. All historical macro tricks I memorized pointed me to queens in this flush. I will keep monitoring for a few weeks and maybe I will have a collection to match ;-). Thanks again for all your help and encouragement brother Christian.

Fungally,

Drew
