is unlikely to be verifiable from images here unless they have been subjected to some kind of color correction/calibration. the first image in this ob. is partially shaded by green leaves, through which some sunlight invariably passes, perhaps casting a green tint on the morels directly beneath. Or if not these seedlings then perhaps the canopy above. that could be responsible for the slight green coloration, or it’s a white balance issue, or an artifact of certain displays. without the photographer’s word that a grey card or some other color correction instrument was used, we can’t be sure that what’s in the frame even roughly approximates what was observed in the field (in terms of color, that is).
While you’re here, Tom, I couldn’t help but notice that the appendix of color images seems to suffer from some the same calibration issues. Color being such a finicky character in Morchella, I would have expected this most recent paper to be hyper-diligent in making sure color be displayed as “accurately” as possible, something akin to the Swedish Cortinarius: Flora Photographica volumes.
Of course, my hat goes off to you a dozen times over for the triumph that is the whole of the article, it’s understandably imperfect parts aside. We’re all happy to have had the opportunity to look at this beloved genus with fresh eyes and fresh names, all thanks to your work and the work of your co-authors.
