🔬 Morphology

Cap

Ivory woodwax

Cap 4-8 cm (young ones 4-5 cm), hemispherical at first, then convex-flattened with a small umbo. White or creamy white, with a faint yellowish tint, especially at the center. The surface is moist AND slimy in wet weather — a thick layer of clear slime. In dry weather it dries out and becomes smooth.

Dripping slimecap

Cap 3-7 cm, hemispherical at first, then flattening out, with a depressed center in mature specimens. Color pure white to creamy white; in wet weather it looks glassy and translucent because of the thick layer of slime. In dry weather the slime dries to a thin glossy film. The cap margin is even, slightly inrolled in young specimens.

Hymenophore

Ivory woodwax

Gilled hymenophore. The gills are widely spaced, thick, and decurrent (a typical feature of the genus). White at first, taking on a cream tint with age. Spore print white.

Dripping slimecap

Gilled hymenophore. Gills crowded, free (not attached to the stem), white. Spore print white. This is the classic structure of the Amanitaceae family, but without a ring or volva.

Stem

Ivory woodwax

Stem up to 10 cm tall, 0.5-1.5 cm thick, cylindrical or tapering toward the base. White; the surface is slimy in wet weather, with a white mealy coating at the top. Hollow inside. No ring.

Dripping slimecap

Stem 5-9 cm tall, 0.5-1 cm thick, cylindrical or slightly club-shaped. White. The surface is very slimy, just like the cap — a hallmark of the species. There is no ring and no volva (unlike true amanitas).

Flesh

Ivory woodwax

The flesh is white, firm in young mushrooms, becoming watery with age. Does not change color when cut. A faint, unremarkable mushroomy taste.

Dripping slimecap

Flesh white, thin, watery, does not change color when cut. Soft when fresh, turns brittle as it dries.

Smell

Ivory woodwax

Faint mushroomy smell, mildly pleasant. Some sources describe a hint of almond or resin. Taste bland, mild.

Dripping slimecap

Odor faint; some sources mention a slightly mealy or cucumber-like note, but in most specimens it is neutral. The flesh tastes mild, with no acridity or bitterness.
