How to tell White dapperling from Deadly dapperling

Cap 4-10 cm across; hemispherical to convex when young, later flattening out with a small bump in the center. Color white to cream, sometimes with pale ochre or cream scales in the center; smooth and silky-white when young. The cap skin is finely fibrous or covered with small, flattened scales. The cap margin is thin, inrolled when young.

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.

Gills. The gills are crowded, thin, free (not attached to the stem). White to cream in young mushrooms, creamy-pinkish with age (hence the Ukrainian name, which means "red-gilled"). The spore print is white to pale pink — an important diagnostic feature (in Agaricus it's blackish-brown).

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 5-10 cm tall, 0.7-1.5 cm thick, cylindrical, slightly thickened toward the base. White to cream. On the stem there's a simple membranous ring, distinct in young mushrooms, may disappear with age. The surface is smooth.

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 of medium thickness, white, with a barely noticeable pink tint at the base of the stem. It doesn't change color 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.

Faint and neutral, with no distinct notes. Don't taste it — its safety status is undetermined.

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.
