Description

Genus: Boletus

Species: vermiculosus

Species 2: pseudo-olivaceous (merged in due to DNA testing)

Common Name: “Brown Pored Bolete”

Tells: Dark brown or red-brown pores pale w/age & bruise a blackish blue. “Vermiculosoides with a darker cap and pores with bruising that does not fade.” Faint chlorine smell.

Other Information: Babies have a yellow cap that ages to a deep or cinnamon-brown shade. Cap may crack w/age. Pale cap flesh stains quickly blue. Boletus vermiculosoides is all but indistinguishable without a microscope, but is supposed to have a lighter brown cap when mature, less brown in the stem, and there is a note that the pore-staining fades in color over time.

Science Notes: Several well respected experts have suggested that B. vermiculosus and B. vermiculosoides may end up getting merged. Whether that’s true will depend on the ongoing effort to gather and test the DNA on more specimens. The former species called B. pseudo-olivaceous has been merged into vermiculosus.

Edibility: Unknown.

CHEMICAL TESTS:

NH4OH (Ammonia): Cap skin reacts in a very variable way, but staining yellow-brown is most common.
KOH: Cap surface turns deep red and/or brown. Cap flesh turns orange.
FeSO4 (Iron Salts): No data.
