Description
Genus: Pulchroboletus
- Genus 2: Xerocomus
Species: sclerotiorum
Common Name: “Whitey’s Bolete”, after Dr. Whitey Hitchcock
Tells: Some-shade-of-red cap. Yellow, blue bruising stem typically has bright red near the base, with dots/smears but not netting. Slightly acidic flavor. Yellow cap flesh stains blue.
Other Information: Stem skin bruises dark blue before fading to brown. Stem flesh is brighter yellow than the cap flesh w/reddish brown bug holes. Red cap skin ages pink to tan, & slowly bruises blackish blue. Bright yellow pores age duller, & bruise blue before fading to brown. Likes moss under oaks & other deciduous trees. Secret Tell: experiments by several good identifiers confirm that a slice will turn brilliant red/orange when placed on a hot pan. Startling!

Got something to discuss?
It seems to me that the apex of the stalk of this bolete can sometimes have red netting. This trait caused me a lot of confusion when I was trying to run specimens which I’m fairly sure were this through the filter.
