Basidiomata medium. Pileus 5–8 cm diameter, parabolic to campanulate when young, plano-convex at maturity, with rounded perforatorium; surface smooth, white (4A1) to grey (6B1) and dark at the center, velar squamulose present on the surface, margin thick, incurved at first then straight or slightly uplifted, often splitting. Lamellae free, white to grey or creamy, 1 mm wide, crowded with four lengths of lamellulae. Stipe 11.5–12 cm long, 1.2 cm wide, cylindrical or subcylindrical, central, solid, surface white to cream or light ash, smooth and glabrous. Annulus membranous, on the upper quarter of stipe, surface white to light ash.

Basidiospores 6.4–9.5 × 4.2–6.2 μm, Q = 1.63, ovoid to ellipsoid; thin-walled, smooth, inamyloid. Basidia 18.5– 19 × 4.8–7.8 μm, sub-cylindric to clavate, four sterigmated, inamyloid. Cheilocystidia abundant, 21.3–35 × 13.8–20 μm, clavate or pyriform, thin-walled, smooth, inamyloid. Pleurocystidia is rarely present, 20–32 × 10–18 μm, similar to cheilocystidia.

Ecology and distribution:— It grows solitary on moist soil. It is widely distributed in Bangladesh, China, India, Ivory Coast, Kenya, Malaysia, Myanmar, Nepal, Pakistan, Sri Lanka, and Thailand.

Material examined:— Sri Lanka.
