that species does NOT blue (nor did the other good example of it here, altho there was a suspicious patch of color on one fruit body, present when first dug up; depite that example being cut and lying about for a couple of days, no other blue color was noted):


This particular Gastroboletus species, collected by David did blue, slowly, on both pores and context.

The spores of the two are similar, tho. Perhaps it is the description that is wrong, and blueing variable?

will post micrographs soon.
