 Description: Pileus 4-7 cm broad, convex, becoming plano-convex to broadly umbonate, glabrous, dry, yellow to ochraceous color, rarely dull cinnamon, margin entire, sterile, often decurved, context up to 2 cm thick, firm, whitish to pale yellow, changing slightly bluish when cut, taste mild to slightly acid. Tubes deeply depressed around the stipe, 8-12 mm thick, yellow. Pores 0.4-1 mm, round, yellow at first, wax-yellow to amber-yellow in age, unchanging when injured. Stipe 5-7 cm long, 9-16 mm thick, ventricose, tapering slightly toward the apex, solid, surface dry, furfuraceous to fibrillose, pale to bright yellow with reddish stains at the base, whitish at the base when cut but briglt yellow in the remainder. Spore print olive-ochraceous brown. Spores 14-16 × 5-6 μm, smooth, narrowly fusoid in face view, somewhat narrowly inequilateral in profile view, pale greenish yellow revived in KOH solution. Basidia 45-52 × 14-16 μm, clavate, hyaline to yellowish revived in KOH solution, sterigmata four, 5-6 μm long. Pleurocystidia 50-75 × 13-15 μm, fusoid-ventricose, thin-walled and smooth, apex subacute, content hyaline to yellowish when revived in KOH solution. Caulocystidia 55-92 × 11-31 μm, clavate to subglobose, smooth, pale brown, soon hyaline in KOH solution. Tube trama divergent from a distinct central strand of nongelatinous hyphae, the divergent hyphae gelatinous, central strand hyaline to brownish in KOH solution.

 Note: The important characteristic of the genus Leccinum is a long coarsely scaly or scurfy stem besides a boletoid tube-trama and rather large, smooth spores of olivaceous umber, brown or pinkish brown color. Therefore we agree with Singer (1945) that the taxon is a Leccinum in spite of the caulocystidia not darkening in age. The collection studied agree with the descriptions given by Smith and Thiers (1971) whom having reports that this is a good edible species.
