[1] Fruit bodies of Lepiota nirupama have caps that start out roughly spherical before becoming convex, ultimately reaching dimensions of 2–3 cm (0.8–1.2 in).

The stem is centrally attached to the cap, hollow, and measures 3.2–4 cm (1.3–1.6 in) long by 2–5 mm (0.1–0.2 in) thick.

The lower surface of the ring is densely covered with fluffy whitish to light brown scales.

Cheilocystidia are plentiful, thin-walled, club-shaped or sac-like with a pedicel, and have dimensions of 10–34 by 7–20 μm; there are no cystidia on the gill faces (pleurocystidia).

[1] The fruit bodies of Lepiota nirupama grow singly to scattered on the ground among bamboo roots both dead and living.
