How to tell Parasol mushroom from Deadly dapperling

Cap large, 10-25 cm across. Egg-shaped at first, then opening out flat like an umbrella, with a small blunt bump in the center. The background color is light gray to grayish brown, and the surface is covered with large brown or grayish-brown scales in concentric rings; the center is darker and smoother. The skin peels easily away from the flesh.

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 and free (they don't touch the stem) — an important feature of the genus. White at first, turning cream to yellowish with age. 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 tall, up to 30 cm high, 1-1.5 cm thick, cylindrical, with a bulb up to 2.5 cm at the base (no volva — this is crucial!). Gray-brown with a distinctive “snakeskin” zigzag pattern of darker scaly patches — a diagnostic feature. Near the top there is a fleshy movable ring (you can slide it up and down), whitish above, with a brown edge below.

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.

The flesh in the cap is white, soft, juicy in young ones, softer and a bit limp in old ones. When cut, it stays white and does not change color — an important difference from similar species. The flesh in the stem is tough and fibrous — not edible.

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 pleasant nutty smell with a subtle mushroomy note. The taste is mild and delicately nutty — especially when fried.

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.
