Cap: 4-20 cm; convex becoming broadly convex or flat; sticky or slimy; smooth; yellowish at first, becoming brown; bruising dark brown; sometimes with partial veil remnants on the margin.

Pore Surface: Attached to the stem or beginning to run down it; yellow, becoming brownish with age; bruising promptly and strongly brown; pores angular, about 1 per mm, not radially arranged; tubes about 1 cm deep.

Stem: 4-10 cm long; 1-3 cm thick; more or less equal; fairly smooth near the apex; partial veil whitish to yellowish, attached near the base of the stem and eventually collapsing against it to form a sheathing ring; white to yellowish; bruising brown.

Flesh: White to yellowish; staining brown on exposure.

Odor and Taste: Not distinctive.

Chemical Reactions: Not recorded. On dried specimens I received red to pinkish reactions from all surfaces with the application of KOH; negative reactions with ammonia; and grayish reactions with iron salts. While distinctive, these reactions are not necessarily reflective of reactions that might be demonstrated on living material.

Spore Print: Dark yellowish brown.

Microscopic Features: Spores 6-9 × 6-8 µ; smooth; subglobose. Pleurocystidia 20-32 × 8-12 µ; fusoid-ventricose.
