How to tell Trooping funnel from Ivory funnel

The cap is very large: 8-20 cm across, convex with an inrolled margin in young mushrooms, later becoming funnel-shaped with a sunken center and a characteristic small brown bump in the central hollow. The color is pale ochre, creamy-reddish, darker in wet weather and lighter in dry weather. The surface is silky-matte and smooth; the margin is often wavy and slightly wrinkled.

Cap 2-5 cm across, convex when young, becoming funnel-shaped over time, with a depressed center and a thin wavy margin. Color whitish, cream, with pale gray or ochre patches; silky-sheened in wet weather, chalky white when dry. Surface smooth, with barely visible radial streaks.

The underside has gills. The gills are crowded, thin, strongly decurrent down the stem. Whitish to cream, turning cream-ochre with age. The spore print is white to pale cream.

Gilled hymenophore. Gills crowded, thin, decurrent down the stem (a hallmark of the genus Clitocybe). Color whitish to cream. Spore print white.

The stem is sturdy: 5-15 cm tall, 2-4 cm thick, cylindrical or thickening toward the base, often with white mycelial fuzz at the bottom. Whitish to cream, matching the cap. The surface is smooth or has fine lengthwise fibers. No ring. The stem flesh is firm, hollow in old mushrooms.

Stem 2-4 cm tall, 0.3-0.8 cm thick, slender, cylindrical, often curved. Color whitish to cream, with white mycelial fuzz at the base. Surface smooth, no ring. Stem flesh firm.

The flesh is thick, white, firm and meaty. It doesn't change color when cut. It has a pleasant nutty-fruity taste. In old mushrooms it's slightly sourish.

Flesh thin, white, watery, brittle. Does not change color when cut. It has a faint, pleasant smell (slightly sweet, or mealy according to some guides) and a mild taste — and that is what makes this species so treacherous: it smells and tastes "right", nothing sets off alarm bells.

A distinct, pleasant mushroomy-nutty smell with a note of ripe apple. One of the most fragrant of the forest Clitocybe. The taste is delicate with a sweetish note.

Faint and indistinct, slightly sweet; some guides describe it as mealy. This adds to the danger: the smell raises no suspicion. Never rely on smell when identifying mushrooms of this size.
