Description

Genus: Tylopilus

Species: intermedius

Common Name: “Bitter Parchment Bolete”

Tells: White cap flesh tastes bitter & stains brown. Oft-wrinkled/lumpy whitish cap & slightly darker stem both bruise yellow- to olive-brown.

Other Information: White/buff pores age pinkish brown & slowly stain brownish. Stem can be netted. Likes oak but not exclusively. Extends from the Carolinas up into Canada & west to at least Michigan, but prefers the warmer parts of that range.

Edibility: Too bitter to eat but useful for unique approaches like cocktail bitters. It isn’t toxic; just absurdly bitter.

CHEMICAL TESTS:

NH4OH (Ammonia): No data.
KOH: No data.
FeSO4 (Iron Salts): Cap skin on young specimens turns pinkish.
