No herbarium specimen

Notes: These robust and heavily reticulated specimens of T. plumbeoviolaceus were displayed at the Clark Rogerson COMA foray. They came from one of the four sites the group visited that day. Note the partially hypomycized pore surface in some specimens.

If it was unknown whether the taste…

was bitter or mild, then I think variobrunneus should be considered. Here’s a visually favorable comparison obs 107451 .

I agree… I’ve never seen plumbeoviolaceus with prominently textured stipes; a totally glabrous stipe with just an occasional hint of fine reticulation at the apex is more typical for this species.
It appears this ID was made based on the colors of the cap and stipe, as none of the other “usual suspects” from the genus seemed to fit into the observed color scheme. The heavy reticulation didn’t seem to bother anyone, and it was probably brushed aside as a developmental anomaly, even though the entire collection sported that feature. To my knowledge no one checked for bitterness, and I don’t recall any “normal” plumbeoviolaceus having been brought from other sites for comparison. Unfortunately, this odd collection was not saved…
By the way, there were two separate collections of enormous T. rubrobrunneus fbs with 7" caps that had yet to fully expand, and both had the upper 1/4-1/3 stipe covered in prominent, but not as course, reticulation.

Wouldn’t have occurred to me…

that these represent plumbeoviolaceus. Coarse reticulations on >50% of stipes and dark bruising on pores don’t fit the BRB concept.
