Notes: > A single large and robust basidiome growing on the edge of a trail in mixed pitch pine & oak woods in the Speedwell section of FPP.
> I’ve posted this species several times on MO — all collections are from the NJ Pine Barrens.
> This is the earliest fruiting I have ever observed.
> The cap of this young specimen was almost 5" in diameter; the stipe was ~7" long and 1.5" wide.
> This material has been preserved.
DNA Sequencing Discussion:
> A clean and contiguous 1368 bps nrLSU sequence has been obtained for this material [the first 70+ bps from the beginning of the LSU region are missing; also there is one Y character corresponding to the nucleotide ambiguity code for either of two the pyrimidine bases, cytosine © or thymine (T)].
> A GenBank BLAST search of the full-length sequence returned no meaningful hits.
> A GenBank BLAST search of a 903 bps sequence fragment returned a nearly perfect match (867/868 bps overlay, 99.9% identity match) to Boletus oliveisporus voucher DPL6823 [accession #KF030254]

collections of pulverulentus.
all components of this mushroom bruise deep blue, including the cap cuticle; the pores are exceptionally sensitive — you can drag a hair across the bright yellow surface and it will blue. The flesh immediately stains blue first and then transitions into brown after a few minutes. Kuo says C. pulverulentus is similar, but stains green-blue, and is much smaller in size.
It’s on my wish list for sequencing.
bruise like crazy? Lots of black, and other shades, all parts? Wondering how close it is to pulverulentus.
This mushroom is an amazing blue stainer, especially on the pore surface. According to a Texas field guide, it’s edible. I haven’t tried it, thought it’s tempting. The flesh is dense and a single large mushroom can easily make a meal. :-)
I hope to see this one someday
