The cap is 30 - 60 mm wide, applanate, sometimes slightly depressed over disc, greyish, sometimes with brownish tinge, and occasionally nearly white; it is glabrous or covered with greyish to whitish, felty to patchy volval remnants. The cap margin is striate (20% - 30% of the radius) and non-appendiculate, and the context is white.

The gills are free, white, and sometimes become greyish when dried; the short gills are truncate.

The exannulate stem 50 - 80 x 5 - 12 (-15) mm, subcylindric or slightly attenuate upwards, fistulose, with a surface that is white to dirty white and nearly smooth; the stipe lacks a basal bulb. At the base of the stip, the volva is saccate, 15 - 20 x 10 - 15 (-25) mm, 1 - 1.5 mm thick, membranous, with an outer surface that is white to whitish, with yellowish brown spots. The upper half of the volva often becoming greyish when mature; the inner surface is usually greyish, but sometimes whitish; and there is an internal limb on the inner surface.

The spores [from east Asia] measure (8.5-) 9.5 - 12.5 (-14.0) x (7.0-) 8.0 - 10.5 (-11.0) µm and are subglobose to broad ellipsoid and inamyloid. Clamps are absent from the bases of basidia.

[Spores from a small amount of northern Indian material measure (9.4-) 10.4 - 12.3 (-14.0) x 8.5 - 10.9 (-11.3) µm. -- RET]
