In herbarium, New Brunswick Museum

Pileus conical, with an inconspicuous small umbo, dry, obscurely striate, glabrous, dull yellow brown (HSV35:50:80), 20 mm in diameter

Stipe cylindrical, rooting deeply into the humus, dry, glabrous, yellow brown (HSV35:60:90), white in the lower half where it is within the substrate, brittle-fibrillose, 150 x 3 mm

Cheilocystidia abundant, ventricose to lageniform, with conspicuous finger-like projections on the narrow upper part, thin-walled, 69-103 x 16-24 µm.

Pleurocystidia abundant, similar to the cheilocystidia.

Pileal trama a thin cutis of roughened (but not coralloid) hyphae embedded in a gelatinous matrix arising from the dissolution of much narrower hyphae.
