Pores and Pore Surface
Pore surface pale yellow when young, olive-yellow in age, immutable; small pores, round to angular.
Equal, stocky, white and glandular above the ring, often adorned with a brown gaiter below; in the absence of gaiter the stipe is white.
The unique characteristic of this bolete is to have a conspicuous white veil, purplish brown on its hidden side.
Flesh: towards bluish gray for KOH, NaOH and FeSO4; nothing for NH4OH, phenol and formalin. Cap and stipe: towards brown for KOH and NaOH, no reaction with phenol and formalin. Tubes: towards brown for KOH, NaOH and FeSO4; towards brownish pink for NH4OH; no change for phenol and formalin.
