A clean and contiguous nrDNA sequence was obtained from this material by Dr. Kudzma. It consists of the last 46 bps of the nrSSU locus, the complete nrITS locus (680 bps) and the first 979 bps of the nrLSU region (thru to and including the LR5 primer). There are only 2 ambiguous characters in the whole sequence; both are located in the ITS region. The ITS and LSU sequences have been posted to this observation.
A BLASTn of the ITS sequence shows this material to be conspecific with obs 206608 (NJ), and because of that it is, therefore, also contaxic with the following sequenced collections: obs 212358 (VT), obs 243052 (NJ), obs 244427 (NJ), and obs 251141 (PA).
Dario’s collection is yet another morphological presentation the common, oak-loving, chameleon-like Neoboletus sp. Unsurprisingly, I’ve been fooled by this thing again! Note the yellow pores, the absence of any red/orange tones in the cap, the yellow dots/squamules on stipe, as well as the unusual separation of the hymenophore from the stipe, all giving an impression of a unique taxon. However, I missed the burgundy staining in the stipe base (typical of this taxon) that should have given me a clue before I chose to sequence this material.

You’re right

I saved for you.

That’s a new one to me. I don’t recall you ever collecting it before, certainly not in your area.
