Observation 104302: Boletus peckii Frost
When: 2012-08-05
No herbarium specimen

Notes: A single basidiocarp growing under mature oaks.
This is definitely the same species as that of obs 73921 collected at the same location the previous year. Same looks, size and stature. The one pictured here had much brighter colors; however, these faded after the mushroom was collected (compare 041.jpg with 009.jpg and the corresponding pics in 73921).

I agree, the bluing might have been more intense when fresh, but in my experience Caloboletus usually doesn’t stain as heavily as Boletus subvelutipes or Baorangia carminipes.
I have recently made my third collection of what I believe is the same species from this particular location, and will be posting it to MO soon. I did preserve a specimen this time and plan to get it sequenced for comparison purposes with my benchmark peckii collection, obs 246697.

Too bad you didn’t slice it open when you collected it.

I bet the blue would have been more intense.
Thanks, GP
