Description

Name in North American Boletes: Gastroboletus turbinatus var. turbinatus AND var. flammeus

Genus: Gastroboletus

Species: turbinatus

  • Species 2: turbinatus var. turbinatus
  • Species 3: turbinatus var. flammeus

Common Name:

Tells: Short, stubby, yellow-red stem stains blue. Wrinkled & pitted, yellow- to red-brown cap. Yellow, orange, or red pores quickly blue. Often grows in fused clusters.

Other Information: Pores are covered by a membrane when young. Yellow cap flesh quickly blues. Cap often bruises blue, slowly resolving to dark brown. Oft-crooked, yellow stem may have red tints by the base, & bruises blue before resolving to blackish. Likes conifers, esp. fir.

Science Notes: North American Boletes lists a parallel species, “var. flammeus.” DNA tests have merged this back into the parent. The flammeus pores supposedly had actual red while the regular turbinatus had yellow to yellow-orange shades. This is now known to be in-species variation.

Edibility: Unknown.
