It is thin and cylindrical to clavate with a taper up from the slightly bulbous base. The surface is smooth and white with white mycelial cords at the base. The thin, membranous, ascending stem ring is white with blackish-grey edges and located about halfway up the stem. Spores: 4.5-6 x 3-4 μm. Ellipsoid to ovoid without a germ pore, oblong to subcylindrical when viewed from the side. Dextrinoid and metachromatic. Basidia: 11.5-19 x 6.5-9 μm. Clavate to spheropedunculate. Four spored.
