Description

Genus: Tylopilus

Species: ferrugineus

Tells: Brown cap & brown stem. White-buff pores tint pink w/ age, & stain brown. Cap flesh stains dull brown.

Other Information: Likes oak. T. badiceps is very similar but this grows larger, ages to have pink tones in the pores, has flesh that stains more brown than pink, has a pink/brown vs. purple/brown spore print, does not have the “beveled cap edge” typical of that one, & lacks any purplish tones in the stem. Both are good edibles.

Edibility: Good.

CHEMICAL TESTS:

  • NH4OH (Ammonia): Cap skin flashes violet to wine-read, before shifting to reddish- to blackish- brown. Cap flesh turns faintly yellowish.
  • KOH: Cap skin turns dark brown to blackish brown. Cap flesh turns faintly yellowish.
  • FeSO4 (Iron Salts): Cap skin turns olive-green. Cap flesh turns blue-green.

There are approx 32 of what I think is Tylopilus ferrugineus growing under an oak tree in my Southern Indiana yard. They are about 6 inches average diameter, light brown caps with white flesh, no reticulation on slightly bulbous, brown stems. They bruise brown and have a very slight bitter or astringent taste when nibbled raw. But I disposed of one in the trash and it later smelled awful, rotten. While I may have a good food source, I am hesitant to cook them now. Opinion/suggestion?
