Description
Genus: Boletus
- Genus 2: Xerocomus (me speculating based on features).
Species: holoxanthus
Common Name:
Tells: Yellow cap, pores & stem flesh all blue quickly & then fade to dark gray. Coarsely red-netted stem & cap flesh also blue & then fade. Xerocomoid pores.
Other Information: In addition to the blues-and-fades characteristics: Yellow cap ages to orange- or golden-brown in the center, cracks & fissures w/age. Yellow cap flesh tastes nutty w/a sour component. Lemon yellow pores age to greenish yellow or olive. Coarse red-netting on a bright yellow stem. Yellow stem flesh is burgundy-red by the base & bug holes. Likes oak. The more widespread B. pseudosulphureus lacks the netting on its stem.
Science Notes: Author speculation here, but this species looks like it belongs in Xerocomus. Huge, broad netting plus wriggly, scriggly, xerocomoid pores? It seems to be a lock. But the name stays where it is until a proper study gets done. Consider it an ID tip!
Edibility: Good.
CHEMICAL TESTS:
- NH4OH (Ammonia): No data.
- KOH: No data.
