The photos do indeed look like tie dye, but the colors were changing so quickly in the field, I did not get the same impression then. As I said, they are drying out now a pure deep yellow. All of the blue and red is gone.

Walt – the caps of all of them were unambiguously brown. I have seen the red of some B. sensibilis. The sweet curry / beef broth smell only lasted an hour. Then is was just ‘mushroomy’.


B.pallidioroseus. photos on MO look too red for this species.

Odor indicates B. sensibilis or B.pallidioroseus. Brown (brick red) points to the former.

Wow, Martin
