Description
Genus: Hongoboletus
Species: americanus
Common Name:
Tells: Pores & flesh bruise blue, evolving to deep brown after 10-20 minutes. Think “red-capped L. pseudosensibilis with red where nature hurt the stem.”
Other Information: Brick red to coppery reddish orange cap ages darker, w/cream yellow zone near the margin. Quick bluing, bright yellow pores age to dull olive yellow. Yellow, blue bruising stem w/vertical red streaks, small red dots by the base; natural injuries present as red. Yellow flesh blues immediately, especially at the base, evolving to brownish orange. Tubes are short, like Lanmaoa. Flesh is solid. May taste a little tart. White mycelium. Only found in mixed pine/hardwood forest to date, but it’s a new species so who knows? All early finds were from the south (Virginia, Georgia, and Mississippi), but expect the range to expand.
Science Notes: First identified in 2024 through whole genome DNA testing, this is one of only two known species in the genus. The other is from east Asia.
Edibility: Unknown, but probably good since the sister species is a common edible in Asia and this has almost certainly been confused with other, known-to-be-edible species here in the U.S.
CHEMICAL TESTS:
- NH4OH (Ammonia): Cap surface turns orange yellow. Cap flesh turns greenish yellow.
- KOH: Cap turns reddish brown. Cap flesh turns ochre (more brown, less red)
- FeSO4 (Iron Salts): Cap surface has no reaction. Cap flesh turns green.
