How to tell Clouded funnel from Frosty funnel

The cap is large: 8-20 cm across, hemispherical to convex in young mushrooms, with an inrolled margin, later flattening out with a small bump in the center. The color is smoky gray, mouse-gray, darker in wet weather and lighter in dry weather. The surface is silky-matte, with a thin whitish bloom (as if dusted with flour). The cap margin is often wavy and curled downward.

Cap 3-7 cm across, convex when young, becoming funnel-shaped over time, with a depressed center and a thin wavy margin. Color whitish to cream, with a pale pink or ochre tint in the center and a characteristic silky, waxy sheen. Slightly sticky in wet weather, matte when dry.

The underside has gills. The gills are crowded, thin, decurrent down the stem. Whitish to cream, turning cream-ochre with age. The spore print is white to pale cream. The gills detach easily from the cap — a characteristic feature of the genus.

Gilled hymenophore. Gills crowded, thin, decurrent down the stem. Color whitish to cream, taking on a pale pink tint with age. Spore print white to pale pinkish-cream.

The stem is sturdy: 5-10 cm tall, 2-4 cm thick, cylindrical or thickening toward the base. White to dirty grayish-cream. The surface is lengthwise fibrous, with white mycelial fuzz at the base. No ring. The stem flesh is firm, becoming hollow with age.

Stem 3-6 cm tall, 0.4-1 cm thick, cylindrical, often thickening toward the base. Color whitish to cream, with white mycelial fuzz at the base. Surface smooth, no ring.

The flesh is thick and white, firm in young mushrooms and looser in old ones. It doesn't change color when cut. It has a distinct mealy smell and a mild taste.

Flesh thin, white, soft. Does not change color when cut. It has a pleasant sweetish smell and a mild taste — as with other poisonous Clitocybe, the lack of any unpleasant smell makes it all the more treacherous.

Strongly mealy, with a hint of cucumber — typical of the species. In old mushrooms it's sourish and unpleasant. The smell is so distinctive that it's used as a diagnostic feature for identification in the field.

Sweetish, pleasant. Raises no suspicion. Taste mild. Don't rely on smell or taste for identification — they give no hint of toxicity.
