Notes: This interesting bolete (two fruitbodies), which remotely looks like Suillus spraguei, was found buried in sandy soil (only top of cap was visible) under pitch pines and scrub oaks.
The overall stature is more like of Suillus though, or maybe Fuscoboletinus. The rims of pore mouths are red, while the tubes themselves are yellow. This discoloration is not necessarily an inherent feature of this mushroom and could have been caused by the weather elements; I have seen a similar phenomenon in a yellow-pored boletes before (e.g., Obs. 767870).
The younger mushroom is 5 cm in height (from tip of root to top of pileus); the cap diameter is 4 cm; the stipe diameter is 1.3 cm.
No bruising of the pore surface or on cap/stipe; the pores are irregular and not radially arranged. The were droplets of greenish liquid (usually associated only with B. frostii) on the pore surface.
The flesh is dense and doesn’t stain when exposed to air.
Ammonia is negative on cap and flesh, but KOH stains both pale brown.

The unseen drama at NEMF. Good luck with that! Let us know what he finds out – and keep looking for more! I can’t help thinking about the Alan’s comment that some of these things only appear once every 40 or 50 years. I am not sure if he was joking or not, but you never know.
In short, the answer is “No”, but I gave the dried specimen to Roy Halling at the conclusion of the NEMF. I hope he finds the time to run DNA analysis or at least do some microscopy. I certainly want to think that this is a new species restricted to the coastal plane that will eventually be named after me. :-)
Did anyone ever come to a consensus on this one?
Quite a striking bolete, indeed. If this one were easy to ID, either you or I would have named it already. :-)
I have dried this specimen, and will eventually get some spore data (maybe at the NEMF). Perhaps then we would be able to at least place it into a genus.
I doubt this is B. flammans — there is no bluing on the pores or exposed flesh.
This should be easy to ID.
