Amanita battarrae or Grisette

Cap 5–10 cm, bell-shaped in young mushrooms, then flattening to plano-convex with a small umbo in the center. Gray-brown with a distinctive zoned pattern — concentric darker bands near the margin. The margin is noticeably radially striate. Surface matte, slightly sticky in wet weather.

Cap 5-10 cm across, hemispherical to egg-shaped when young, later becoming convex-flat with a low umbo. Color gray, ash-gray, mouse-gray, darker at the center. Surface smooth, slightly slimy in wet weather. The cap margin has characteristic radial grooves (like the ribs of an umbrella), a diagnostic feature of section Vaginatae. Whitish patches of veil remnants may stay on the cap.

Gills free, white, crowded. Spore print white.

Gilled hymenophore: the gills are free, crowded, pure white. Spore print white.

Stem 7–12 cm tall, 0.8–1.5 cm thick, cylindrical, more slender than the cap. White or cream, sometimes with faint grayish scale-like patches. THERE IS NO RING — this is the key feature of section Vaginatae. At the base — a large, white, sack-like volva (remnants of the veil).

Stem 10-18 cm tall, 0.8-1.5 cm thick, thin, slender, tall, slightly thickened toward the base. Color whitish, sometimes with fine grayish fibers or a zigzag pattern. No ring. At the base: a sac-like, eggshell volva, just like the destroying angel's.

Flesh white, thin, brittle. Does NOT change color when cut. Springy in young mushrooms, crumbly in mature ones.
