Strobilomyces sp.
Cap - dark pyramidal scales with projecting marginal veil remnants;
Flesh - off white changing to orange / red slowly (within 60 seconds) of injury and turning almost black within 5 minutes
Tubes - adnexed colour change as above, same with pores
Stipe - 12 x 2 cm approx. colour change as above; area below ground remained pale grey.
I did not collect spore print on this trip.
Dr. Roy Halling's comment:- Yes , indeed, it's a Strobilomyces. It should have round black spores. Ornaments can be reticulate or some other ornamentation.
