NOTE: THERE IS A WORKSHOP with the BLUE COLOURED section and red tube details.

Pileus 8-15 cm broad when mature, convex when young, becoming broadly convex to plano-convex to plane to occasionally umbonate or shallowly depressed with age; surface dry, even, smooth to occasionally rugose to reticulate on the disc, obscurely tomentose to velutinous to occasionally appressed fibrillose when young, frequently glabrous with age; color when young brown, with age red on the disc and reddish brown toward the margin, usually darkening and appearing water-soaked when bruised; margin incurved to broadly decurved, entire. Context 1-3 cm thick, firm, compact, yellow, bluing quickly when first exposed, then often fading to buff. Taste and odor often pungent, unpleasant.

Tubes 1-2 cm in length, deeply and broadly to narrowly depressed around the stipe, yellow , bluing when bruised; pores small, 0.5-1 mm broad, angular, typically red, sometimes near reddish orange, bluing when bruised.

Stipe 8-12 cm long, 1.5-3.5(6) cm thick at maturity, clavate to subclavate to occasionally equal to tapering toward the apex, solid, with white rhizomorphs attached to the base; surface dry, glabrous to more commonly punctate to obscurely velutinous or fibrillose, not reticulate; typically yellow at the apex, usually with yellow background for entire length but marked with red granules , basal portion often appearing reddish brown. Context yellow except reddish to reddish vinaceous in the base, bluing when exposed.

Spore print ochraceous brown. Spores 13-16 X 4.8-5.5 Ám ochraceous in KOH, dark ochraceous in Melzer's, moderately thick-walled, smooth, subcylindric to subfusoid.

Basidia 18-24 X 7-10 Ám, hyaline, four-spored, contents granular in KOH. Hymenial cystidia 39-45 X 9-11 Ám, scattered to numerous, sometimes embedded, subclavate with tapering apices to basidioid, often heavily incrusted and staining bright ochraceous in KOH, occasionally hyaline and apparently not incrusted.

Habitat, and distribution Solitary in soil in mixed forests. A mycorrhizal host has not definitely been established; however, oaks have always been in the vicinity where basidiocarps were found.

It is rated as edible by some and unedible by other, the presence of the red pores should serve as a warning to be very careful when first trying it.

I found this info HERE.

Hope you like!
