Bitter taste (see Eva’s comment below) eliminates badiceps.

is more vinaceus-violet than purple and usually less robust in stature than plumbeoviolaceus. I frequently find that even its pores sometimes have pinkish-violet hues. I think one is more likely to confuse violatinctus with rubrobrunneus than with plumbeoviolaceus.

Dark purple lacking in brown/tan looks more like plumbeovilaceus to me. Although the stipe does look more like rubrobrunneus.

A good example of why rubrobrunneus/plumbeoviolaceus/violatinctus are easily confused.

Looks like I have found/IDed rubrobrunneus with the dark-plum purple cap, although not confidently, obs 70441.

From the latest Bessette NA bolete book found in look-alikes under violatinctus, “plumbeoviolaceus… has a dark purple cap”, “rubrobrunneus has a… purple brown to vinaceus brown cap”. From the violatinctus description of stalk, “concolorous with the cap or paler when young, becoming brown in age with a white apex.”

it is the purple cap that eventually becomes brown, and the purple stipe remains purple even though the color may fade somewhat. In this young collection, the stipe is whitish at the apex and brown below.

…and brown stem could also suggest rubrobrunneus. The colors appear to be accurate as the flash didn’t fire. We need to know about the taste to eliminate some options from consideration.

Didn’t I get bit on this one last year?

The cap made me think Black Velvets, but then the stem is too brown and we ended up at Ty. atronicotianus (which may be bitter or may not). Ty. atratus was a distant possibility written off for rarity, and Ty. ferrugineus for the cap being too black.

Have I got that right or do I need to do more refining?

Bitter or mild?
