Description

Genus: Tylopilus

Species: atronicotianus

Common Name: “Tobacco Stain Bolete”

Tells: White pores age to reddish brown & stain red/brown or black. Brown stem darkens going down to nicotine-stain-blackish, often ending in a “V” shape with a tiny taproot.

Other Information: Dark brown cap bruises blackish & is usually cracked to some extent even when young. White cap flesh slowly stains pink, resolving blackish. Stem flesh goes from white by the pores to brown/black in the root. Angular, irregular pores can be huge (as big as 1.5 mm wide).

Edibility: Unknown, but vaguely unpleasant and disappointing, especially if you thought you had T. alboater.

CHEMICAL TESTS:

NH4OH (Ammonia): Cap skin turns blackish brown to reddish black. Cap flush turns pale grayish yellow surrounded by black.
KOH: Cap skin turns reddish brown to brown. Cap flesh turns reddish orange to bright orange-amber or amber-brown with a black ring.
FeSO4 (Iron Salts): No data.
