Name in North American Boletes: Boletus hemixanthus

Genus: Xerocomus

Genus 2: Boletus

Species: hemixanthus

Species 2: hypoxanthus
Species 3: ochraceoluteus

Common Name:

Tells: Yellow pores DNS or bruise blue-greenish & can be huge, esp. by the stem. Brown (chestnut, reddish or dark) cap may crack w/age. May taste sour.

Other Information: Pale yellowish flesh DNS or may bruise blue, often with a reddish phase in the cap flesh but not in the stem. Stem has raised, reddish-brown ribs by the pores. White to yellowish-white mycelium. Likes oak and/or pine woods.

Science Notes: DNA testing of identified samples moved this mushroom into the newly erected genus “Xerocomus,” and knowledgeable experts from the region have suggested this as the surviving species of a merger with Xerocomus hypoxanthus and Boletus/Xerocomus ochraceoluteus.

Edibility: Unknown.
