Cap: 20-80 mm diameter, convex to plano‑convex, sometimes slightly depressed in age. Colour pale buff, pale grey‑buff, or greyish‑sepia, often darker at the disc. Surface dry, not viscid. Universal‑veil remnants appear as fine, powdery to granular patches, sometimes forming low, irregular warts. These are greyish sepia to fuscous, giving the cap a muted, dusty appearance. Margin distinctly striate, sometimes splitting.
Gills: White to pale buff, free, moderately crowded. Short gills subtruncate. Edges smooth to slightly uneven.
Stipe: 25-70 mm tallx 4-10 mm thick, hollow or partially hollow. Colour white to pale buff or pale greyish sepia. Upper stipe smooth to faintly floccose; lower stipe smooth. Base clavate to slightly bulbous (8-15 mm wide). No ring (exannulate).
Volva: Present as a rim or band of powdery, greyish sepia volval material at the stipe base. Volval cells are globose to ellipsoid, often finely encrusted—similar to A. nehuta but generally finer and paler.
