On sandy soils, with a head (spore sac) 0.6 to 1.3 cm across, pale cream to greyish-white, with a conical peristome, a light brown gleba, a cylindrical reddish-brown stipe 3 to 6 cm long, its surface covered with abundant scales.

Capillitial hyphae very thick-walled, branched, with swellings at the septa, 4 to 7 µm wide, with a characteristic wavy lumen, and with distinct septa (without clamp connections).

Basidia clavate, tending to disappear upon spore formation, 15 to 22 µm long by 5 to 8 µm wide, and tetrasporic, with sterigmata up to 4 µm.

Spores spherical to subglobose, moderately thick-walled, with very prominent digitiform warts, yellowish under the microscope, 4 to 5.5 µm long by 3.9 to 5 µm wide, ornamented with coarse warts evenly distributed over their entire surface, and inamyloid in Melzer's reagent.
