Notes: A very strange looking Boletus sp. Looks somewhat similar to B. nobilis or B. gertrudiae, but is neither. The cap is tan, the stipe is pale tan, and both were tinged greenish in natural lighting (fading away after handling and not visible in pics). The stipe is devoid of reticulation (lightly reticulated at the apex) but textured with closely-spaced and twisty longitudinal ribs/striations. The context is negative with either KOH or ammonia. The pore mouths don’t stain pinkish-red as in obs. #74821. Any ideas?

with the red/yellow types this summer have been the bruising/staining patterns that seem to defy specification, as well as the unusually prominent red on the stipes of many that I have determined are not true bicolor. Moreover, many of my collections which I would call true bicolor have shown stronger bluing on the pores and/or stipes (generally virtually none on the context, except for one collection which blued slowly but prominently on the cut flesh) than what I’d expect in bicolor.
Our local rainfall here in eastern PA, and the rain in NJ, is very low Ph. I often wonder if this could contribute to the chemical makeup that causes the bluing. And, if so, does amount of rainfall contribute to the bluing?
I’ve already seen your observation before, and I know that your bolete (a very interesting specimen) is not in B-R-B. This summer, I have encountered many mysterious boletes, mostly from the bicolor group, that did not match anything to my satisfaction in the bolete encyclopedia and trusworthy Internet references, and I’m sure it’s been the case with you as well. It’s very exciting at first, as any challenge of this kind, but when you exhaust all the possibilities without making any progress, frustration and disappointment quickly set in. I’m beginning to believe that the big bolete book is already obsolete and in need of revision…
