Cap:
2.5-5cm across, convex; tawny brown, often reddish at center; dry, fibrillose - finely scaly

Flesh:
whitish at first

Gills:
adnexed, slightly sinuate, close, narrow; brownish red becoming dark purplish brown or black

Stem:
5-10cm x 0.4-0.6cm, equal, slender, rigid, hollow; color like or a little paler than cap; fibrillose - finely scaly

Microscopic spores:
spores 9-12 x 5-5.7 microns, elliptic-truncate to ovate-truncate in face view, in side view somewhat elongate-inequilateral due to broad suprahilar depression, "weakly to distinctly ornamented with small warts to appearing almost smooth", apex truncate but typically not snout-like, in KOH dark bister becoming dark chocolate color, in Melzer''s reagent dull bay-red, "wall about 0.2 microns thick"; basidia 4-spored, 20-24 x 8-10 microns, colorless to (when old) weakly brownish at base in KOH; pleurocystidia 42-56 x 9-14 microns, "scattered or in fascicles, often rare, cylindric but often flexuous [wavy], subclavate, to subcapitate or abruptly tapered to a point at apex", walls thin, smooth and colorless, content not distinctive in KOH or Melzer''s reagent, cheilocystidia 50-64 x 9-12 microns, filamentose to subcapitate, colorless, thin-walled, smooth; fibrils of cap surface are mentioned as clamped

Spore deposit:
[presumably purplish brown or blackish]
