Observation 74031: Lanmaoa G. Wu & Zhu L. Yang
When: 2011-08-15
No herbarium specimen

Notes: I posted observations for this type of mushroom a little over a week ago. Collected a few more today. If not for the vivid red on the stipes, I’d propose “Boletus pseudosensibilis.” Blue bruising on pores is rapid and fairly intense, and the blue changes to reddish brown within an hour. Bluing of cut context is slow, and also fades to reddish brown or brown. No odor. Under oak.

KOH darkens cap, and is orange to orange brown on stipe, stipe context, cap context, pores, and tubes.

Recognized by sight: Despite the red on the cap. Both boletebill and I.G. Safonov have recently posted similarly red stiped boletes as “pseudosensibilis.” Given the dull red cap color, bluing of all parts, and lack of any distinctive odor, this seems like the most reasonable proposal.

As per other discussions, the biggest problem I’ve had with this type is the prominent red on the stipe. Looks like this may be a highly variable trait throughout this entire red/yellow complex.

flesh seems to blue too much for bicolor so I’m with you on this pseudosensibilis

No smell I guess.
