When: 2014-11-23

Collection location: El Dorado, California, USA [Click for map]

Who: Andrew S (AmatoxinAndy)

No specimen available

Growing in leaf litter below clump of live oak trees. A couple similar specimens nearby. Cap 9 cm diameter; stipe 8.5 cm long. Cap upper surface red-brown to copper, though with greenish-yellow/olive haze in spots. Definitely a bolete: tubes on lower surface of cap orange-ish. Outer surface of stipe orange-ish. Inside stipe and cap bright yellow, bluing immediately when cut (one picture shows a stipe immediately after cut side-by-side with one made a few minutes early). Stipe tapered immediately below cap. “Boletus dryophilus” seems to fit best but no experience with it.


cut stipe of smaller specimen shows yellow flesh immediately post-cut (right) and blued stem a few minutes post-cut (left)
best specimen; lighting doesn’t do color justice. See notes.
lighting not best, but orange-ish underside of cap visible
