 Description: Pileus 2.5–5 cm broad, broadly conic to convex, the margin incurved, expanding to broadly conic-umbonate with a decurved margin, margin typically appendiculate with veil fragments, surface glutinous, viscid when wet, coarsely fibrillose, cuticle at first ocher-red, fading in age, context up to 0.8 cm thick, yellow, changing to pinkish gray upon exposure. Tubes adnate to decurrent, about 5 mm deep, bright yellow. Pores concolorous with tubes, angular, 1–1.5 mm broad, smaller toward the pileus margin, often compound, changing to reddish or brownish when injured, spotted brown from tufts of cystidia. Stipe 3–5 × 0.6–1 cm thick, enlarged downward with a clavate base, solid, context white in the interior or brownish at the base, cortex yellowish, lower portion sheathed with remains of a fibrillose coating similar to the fibrils of the pileus and breaking into patches, apex yellow and somewhat reticulate with decurrent lines from the tube. Spore print dull purplish drab. Spores 8–12 (14) × 4.5–5 μm, smooth, narrowly ovate in face view, narrowly inequilateral in profile view. Basidia 30–37 × 8–10 μm, subcylindric to clavate, colorless in KOH solution, sterigmata four, 4–5 μm. Pleurocystidia 55–70 × 5–7 μm, subcylindric, flexuous or straight and with a subacute to obtuse apex, colorless and thin-walled, usually with bister incrusting material near the base. Hymenophoral trama gelatinous and divergent. Pileus trichodermium of loosely tangled hyphae with short inflated cells near apex and with orange-buff content revived in KOH solution. Clamp connections absent.

 Note: This species has a extremely viscid pileus and is recognized by the dense woolly, dry red coating on the pileus and stipe. The flesh stains reddish on bruising and this color persists on cut surface of dried specimen. Its spore deposit is purplish, not cinnamon to olive of the genus Suillus (Smith and Thiers, 1971). It is mycorrhizal with species Picea or Pinus.
