Tells: Cap flesh tastes lemony. Well-netted stem w/viscid-when-wet bottom, often w/white mycelium. 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. White cap flesh often has a rosy tinge & slowly stains yellow-brown. Likes pine, especially Scots Pine. An eastern version of the Admirable Bolete (B. mirabilis).
