Name in North American Boletes: Boletus projectellus
- Genus 2: Boletus
- Genus 3: Boletellus
- Genus 4: Ceriomyces
Tells: Cap flesh tastes lemony. Well-netted red to brown stem. Likes sandy soil and pine, esp. Scots Pine. Cap edge projects past the pores to form a ridge.
Other Information: Yellow pores age toward brown & bruise lemon yellow. Cap shape often shifts from from a hamburger bun to a “cupcake” shape as the tubes extend in maturity. Cap surface often cracks in age. Stem is viscid when wet, and often has a visible white mycelium. White cap flesh often has a rosy tinge & slowly stains yellow-brown. An eastern version of the Admirable Bolete (Aureoboletus mirabilis).
Science Notes: DNA testing moved this mushroom into the newly erected genus “Aureoboletus” (“Aureo” from the characteristic sunny-yellow pores). Reports have been received that this species has hopped the pond and can now be found in Europe too, particularly along the Baltic Sea but with a range that spreads hundreds of miles inland.
Edibility: Good. Reported to be much better when fresh.
- NH4OH (Ammonia): No reaction.
