Product Description

Species: plumbeoviolaceus

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 w/a cap that bruises violet, and T. rubrobrunneus, which has more brown. All are absolutely beautiful, meaty mushrooms. It’s a genuine shame they taste so awful.
