Description

Name in North American Boletes: Boletus griseus var. fuscus

Genus: Retiboletus

  • Genus 2: Boletus

Species: vinaceipes

  • Species 2: griseus var. fuscus

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.

Edibility: Good.
