Its cap is white in colour, and 7–15 cm (2.8–5.9 in) across.
It is oval to convex in shape.
The surface is dry but sticky when wet.
The cap surface is characterized by large pointed warts, white to brown in colour.

Gills are closely spaced and free from the stem.
They are cream at first, but can turn white as the mushroom matures.
Short-gills are frequent.
Stem is white, measuring 10–20 cm (3.9–7.9 in) long and 1–2 cm (0.39–0.79 in) thick.
It tapers slightly to the top, smooth to shaggy in texture.
There is a ring, thick and often double-edged, the underside being tissuelike.
The universal veil hangs from the top of the stipe.
The basal bulb is considerably large in size, with concentric circles of down-turned scales.
The volval remnants stick to it and cause irregular patches.

Spores are white, elliptical and amyloid.
They measure 11-14 x 6-9 μm, and feel smooth.
Flesh is white, and shows no change when exposed.
There is no distinctive odour, but some specimens may develop the smell of decaying protein.
