Observation 73921: Boletus peckii Frost
When: 2011-08-13
No herbarium specimen
0 Sequences

A single basidiocarp growing under oaks and other hardwoods. Though this bolete is lacking vivid tones, the brown cap nevertheless contrasts nicely with the dull purple-red reticulated stipe and pale beige-gray pore mouths. The context tastes somewhat bitter, but not anything like T. felleus or T. plumbeoviolaceus. This is the first time I see something like this, and I cannot even place it into any major bolete clade.


The context blues instantly, but it takes the color a few minutes to reach maximum intensity, at which time it slowly begins to fade away.
Staining of the context with 3% aqueous KOH (left half) and ammonia (aq) [right half]
