Common Name: “Violet Gray Bolete”
Tells: Purplish stem is marbled or streaked w/white, & browns w/age. Cap is similar but browner, often w/a whitish bloom. Bitter, white cap flesh DNS.
Other Information: The stem may have a tiny bit of netting at the very top, and may bruise olive or olive-brown. Compare to T. violatinctus, which is more pink than purple, has a cap that bruises violet, and tends to be buggy (plumbeoviolaceus rarely has bugs). Also compart to T. rubrobrunneus, which has more brown. All are absolutely beautiful, meaty mushrooms. It’s a genuine shame they taste so awful.
Edibility: Too bitter to eat but useful for unique approaches like cocktail bitters or bittersweet candied products. It isn’t toxic; just absurdly bitter in a way that gets worse when you cook it.
