Description

Name in North American Boletes: Boletus griseus var. fuscus

Genus: Retiboletus

Genus 2: Boletus
Genus 3: Xercomus

Species: vinaceipes

Species 2: griseus var. fuscus
Species 3: fuscus (the name used at MushroomExpert.com)

Common Name:

Tells: Grows with pine. Bugs leave dark brown holes w/bright yellow stains in flesh that may stain slowly red. White-gray, red-staining stem has broad netting that darkens w/age.

Other Information: Likes pine (regular griseus likes oak), and also has a darker gray cap, and a stem that is a little more red toward the bottom. The stem flesh may also be a little more yellow that griseus‘. Like the regular version it has an unfortunate tendency to be bug-infested. Some outlier collections have blued in cut flesh.

Science Notes: Once supposed to be an invasive Japanese species, this is now understood to be a native counterpart to R. griseus that evolved to live with conifers rather than hardwoods, and has an Atlantic coast range from Canada to Central America. BOENA lists R. vinaceipes as an independent species from R. griseus var. fuscus.

Edibility: Good.

CHEMICAL TESTS:

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