Description

Name in North American Boletes: Boletus pseudosulphureus and pseudosulphureus var. pallidus

Genus: Neoboletus

Genus 2: Boletus

Species: pseudosulphureus

Species 2: junquilleus

Common Name:

Tells: Bright yellow cap ages red/browner & bruises blue-black. Bright yellow flesh & pores blue quickly, w/pores resolving to brown. Stem flesh is dark red by the base, which blues faster.

Other Information: Cap flesh may have a greenish tint. Yellow stem bruises blue & then resolves to brown. Stem usually has no netting. Cap flesh may taste a little acidic or astringent. Likes oak & pine.

Science Notes: Nova scotia has a variety with a paler-than-usual cap color and flesh. This was considered a different species (var. pallidus in North American Boletes) but has since been shown to be a natural variation within the single species under the newly erected genus “Neoboletus.”

Edibility: Edible.

CHEMICAL TESTS:

NH4OH (Ammonia): Cap skin has no reaction.
KOH: Cap skin turns orange to reddish. Blue-stained cap flesh turns orange.
