How to tell Leucoagaricus nympharum from Deadly dapperling

Cap 4–10 cm, egg-shaped at first, opening with age to flat-expanded with a low, barely raised, pale brownish umbo in the center. White in color, the surface covered in fibrous white scales — the typical "parasol" texture.

The cap is small: 2-5 cm across, hemispherical to convex in young mushrooms, later flattening out with a broad, low bump in the center. The color is pale cream or pinkish-cream overall, with characteristic concentric rings of reddish-brown or brick-colored scales (as if dusted with ground pepper). The scales are denser at the center of the cap and sparser toward the edge. The surface beneath the scales is smooth.

Gilled hymenophor. Gills crowded, free, not attached to the stem. White at first, with age taking on a faint pinkish tint; they darken when pressed. Spore print white.

Gilled hymenophore. The gills are crowded, thin, free (not attached to the stem). Color white to cream, cream-ochre with age. The spore print is white — an important feature for telling it apart from Agaricus mushrooms (theirs is chocolate-black).

Stem 5–12 cm tall, 0.5–1 cm thick, slender, cylindrical, with a bulbous swelling at the base. White. It has a broad, movable milky-white ring.

Stem 3-6 cm tall, 0.3-0.7 cm thick, cylindrical, slender. Whitish in the upper part, and in the lower part with reddish-brown or pink tones and small scales. The ring is either absent or present as a thin, indistinct band of scales — practically invisible in mature mushrooms. The stem flesh is firm.

Flesh white, thin, tender. On exposure to air it gradually whitens in the lower part of the stem. No sharp color changes when cut.

Flesh thin, white, with a pinkish tinge in the lower part of the stem. Doesn't change color quickly when cut. No pronounced odor — a delicate fruity smell.

A faint radish smell. Mild taste, without distinct notes.

Faintly fruity-sweet, reminiscent of apples — and that's exactly what makes it so treacherous. The smell doesn't raise alarm; it's even appealing, especially to children. Don't rely on smell or taste for identification — neither signals deadly toxicity.
