Description

Genus: Boletus

  • Genus 2: Xerocomus

Species: ochraceoluteus

Common Name:

Tells: Bright yellow pores bruise slowly blue. Pale to bright yellow cap flesh stains reddish & resolves to bluish green, but stem flesh has no red phase.

Other Information: Pale yellow stem bruises red (rarely blue), & gets redder going down. Small (<3″), slightly viscid yellow, orange-tan to pale pinkish cinnamon cap cracks w/age & has yellow by edge. Likes oak & oak-pine woods. Found in Florida.

Science Notes: Knowledgeable experts on southern boletes suggest that Xerocomus hemixanthus and Xerocomus hypoxanthus are probably older names that should be merged into this one; which most likely belongs in either Xerocomus or Xerocomellus. There is no way to be sure unless/until the original holotypes of those species can be DNA tested.

Edibility: Unknown.

CHEMICAL TESTS:

  • NH4OH (Ammonia): Cap skin turns reddish brown.
  • KOH: Cap skin flashes orange before turning reddish brown.
  • FeSO4 (Iron Salts): Cap flesh turns grayish green.
