Name in North American Boletes: Boletus pseudosensibilis
- Genus 2: Boletus
Tells: Yellow pores age brownish & bruise blue before slowly fading to brown. Yellow flesh stains blue.
Other Information: Cap usually reddish brown but can be a dingy yellow-brown, & often gets cracks that show the yellow flesh. Yellow stem may have reddish tints, esp. toward the bottom. Ammonia turns cap skin greenish blue, resolving to purple. Note: the typical bluing can be seriously delayed by age, youth and environment.
Science Notes: DNA testing moved this mushroom into the newly erected genus “Lanmaoa” (named after Lan Mao, the medieval Chinese naturalist who first studied what we now call boletes). Members of this genus tend to have shallow pores like Baorangia bicolor, but are genetically closer to the new genus Cyanoboletus. Go figure.
- NH4OH (Ammonia): Cap surface turns blue, then dull purple (even on dried specimens).
