Tylopilus badiceps

 

No Common Name

Synonyms: 

Substrate: Ground

Location: Hardwood Forests

Spore Color: Pinkish Brown 

Pore Color: Whitish Becoming Pinkish

Comments: 

This group of Boletes can be tough to separate out sometimes. Tylopilus is most often defined by a pinkish pore surface, but you will not see the pink in this species. Start off my looking for a whitish pore surface that bruises brown. As the mushroom ages, the pore surface will go from whitish to brownish, never turning pink.

Next, there should be maroon colors in the young cap, no reticulation on the stem, and a stem that is colored similarly to the cap. The taste of this mushroom should also NOT be bitter.

Chemical Reactions:

NH4: Cap turns some shade of amber. Stem turns blackish brown. (From NA Boletes)

Lookalikes:  

Tylopilus ferrugineus lacks the marron colors and the cap also flashes violet with NH4 and dark brown with KOH. Context stains blue-green with NH4. Tylopilus felleus has prominent reticulation on the stem.  Tylopilus rubrobrunneus has a bitter taste and a pore surface that bruises pink. Tylopilus indecisus has more of a whitish stem and possibly some reticulation near the apex of the stem.
