Originaldiagnose:
"Pileus 3–10 x 2–5 mm when closed, cylindrical to ellipsoid, later campanulate, finally applanate, up to 20–25 mm when fully expanded, whitish to pale ochraceous when young, becoming grayish to blackish on aging, plicate when expanded; surface longitudinally translucently striate, covered with a whitish, floccose to woolly, but compact veil, with a soggy appearance; veil soon disappearing. Lamellae up to 1.5 mm broad, ventricose, white when young, blackish and distant when mature, with whitish fimbriate edge. Stipe 30–50 3 0.5–2 mm, slender, hollow, fragile, covered with fine, floccose to woolly white veil remnants, whitish or pale grayish. Odor and flavor indistinct.
Basidiospores [40,1,1] 7.8–9.7 x 5.0–6.0 µm, on average 8.9 x 5.5 mm, Q = 1.44–1.64 (1.76), Qav = 1.6 in frontal view ellipsoid, often with one side somewhat depressed or straight, giving a subphaseoliform outline, ellipsoid to subamygdaloid in lateral view, not lentiform in polar view, dark reddish brown in KOH, almost opaque, with small hilum and a central, 1.4–1.7 µm wide germ pore. Basidia fourspored, bimorphic, clavate or spathulate with a median constriction, 23–28 x 7–8 µm. Pleurocystidia absent. Cheilocystidia abundant, 27–48 x 10–18 µm. variable shape, ranging from almost globose to subglobose, vesiculose, ellipsoid to broadly utriform, most frequently vesiculose with short pedicel. Veil made up of sausage-like hyphae constricted at the septa, with fusiform-cylindrical end cells (40–78 x 18–22 µm). Clamp connections present.
