Description

Name in North American Boletes: Fuscoboletinus grisellus

Genus: Suillus

Genus 2: Fuscoboletinus

Species: grisellus

Common Name: “Grayish Suillus”

Tells: White/gray/brown pores run down stem (decurrent) & DNS. Likes sphagnum moss under larch, usually in wetlands.

Other Information: Stem flesh is white on top, yellow in the middle, red-orange by the base, & DNS. White/gray cap, maybe w/yellowish tints, is usually dry or slightly viscid & may be scaly. Whitish cap flesh DNS. White to olive- or tan-gray cap & stem, maybe w/yellow tints.

Science Notes: DNA testing eliminated the genus Fuscoboletinus and moved all its members to Suillus except for paluster, which has been placed (probably for just the moment) in Boletus.

Edibility: Good.

CHEMICAL TESTS:

NH4OH (Ammonia): Cap skin turns pale pink. Cap flesh turns pale pink.
KOH: Cap skin turns pale reddish-brown. Cap flesh turns pale pinkish-red that quickly resolves to pinkish-gray.
FeSO4 (Iron Salts): Cap skin turns bluish-gray. Cap flesh instantly turns bluish-gray.
