Description

Genus: Boletus

Species: mottiae

Common Name: “Mott’s Bolete”

Tells: Viscid, wrinkled, cinnamon to browner cap fades toward the edge. Netted, buff to pinkish-cinnamon stem. White pores age to yellow.

Other Information: Found only in Grass Valley & Nevada City, CA. Spore print color unknown. Extraordinarily rare.

Edibility: Unknown, but the similarity to edulis variations is a very good sign.

Science Notes: This site has a good article on edulis-kin whole genome testing (a particularly good one if you want to delve into this species) that discusses how recent work has thrown the name of this mushroom into dispute. Strict adherence to the rules (despite an obvious human error) would require a merger of the well known B. regineus into this species name, with the extraordinarily rare species people have always called B. mottiae getting a brand new name. This site will refrain from such chaotic and confusing changes until absolutely necessary. Again, see the article for details.

CHEMICAL TESTS:

NH4OH (Ammonia): No reaction.
KOH: No reaction.
FeSO4 (Iron Salts): No reaction.
