How to tell Ivory woodwax from Death cap
How they differ, how to recognize them and which is more dangerous — a mushroom comparison
Warning: Death cap(Amanita phalloides)
DEADLY POISONOUS
Eating it can cause death. Do not pick it and do not taste it.
Contains amatoxins (α-amanitin), which block RNA polymerase II, causing necrosis of liver and kidney cells.
The first symptoms (nausea, vomiting, diarrhea) appear 6–24 h after eating, most often after 8–12. Then, around the second day, comes a deceptive improvement. After that, from the third day, acute liver failure sets in.
At the slightest suspicion — go to the hospital immediately. A specific drug does exist: intravenous silibinin, registered in Ukraine precisely for death cap poisoning. But it hasn't turned out to be a magic antidote — controlled studies have never proven its effectiveness. Most of the work is done by simpler things: many hours of IV drips, sorbents, intensive care, and in the most severe cases a liver transplant. The sooner you get to the hospital, the more options the doctors have.
If you suspect poisoning, call an ambulance immediately: 112 (the European emergency number) or your local emergency number
The short answer
Ivory woodwax and Death cap look alike, so they're easy to mix up — but Ivory woodwax is edible, while Death cap is deadly poisonous. The main visible difference: season: Ivory woodwax — autumn, Death cap — summer, autumn. The mushrooms also differ in the following features: use, cap color, cap shape. If you have even the slightest doubt, leave the mushroom be.

🔬 Morphology
Cap
Death cap
The death cap's cap is 5–15 cm across. In young mushrooms it is hemispherical, later becoming flat and spread out.
The color varies from olive green and yellowish green to grayish and almost white — which is what makes identification tricky. The surface is smooth, slightly slimy in wet weather, with a characteristic radial pattern of darker fibers spreading from the center. The cap margin is even, without striations.
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.
Hymenophore
Death cap
The hymenophore is lamellate. The gills are crowded, thin and free — not attached to the stem. In both young and mature mushrooms they stay pure white — this is a critical diagnostic feature.
Not a hint of pink, cream or ochre, as in true Agaricus mushrooms. The gap between the gills and the stem is clearly defined. The veil is white and membranous, completely covering the hymenophore in young specimens.
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.
Stem
Death cap
The stem is slender, 7–15 cm tall and 1–2 cm thick. Cylindrical, widening at the base into a characteristic club-shaped bulb wrapped in a membranous sack-like volva — the main diagnostic feature.
The color is whitish green, often with a snakeskin pattern of faint bands. In the upper third there's a well-developed, hanging white ring with remnants of the veil. The surface below the ring is faintly scaly.
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.
Flesh
Death cap
The flesh is white and doesn't change color when cut — and that's the treacherous part: none of the safety signs foragers are used to relying on work here. The flesh is thin and brittle in the cap, fleshy at the base of the stem.
It doesn't change color on contact with air, neither after a minute nor after an hour. No "lovely white flesh" should reassure you — it's precisely in the white flesh of the death cap that the concentration of amanitins is highest.
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.
Smell
Death cap
The smell of a fresh mushroom is faint and hard to notice; in young specimens it's almost absent. Mature ones develop a slight sickly-sweet note, like wilted honey or stale dough.
This aroma isn't distinct enough to warn an inexperienced forager. Like other poisonous amanitas (the fly agaric, the panther cap), the death cap has only a faint, indistinct smell that gives no warning — yet another treacherous trait. A stronger odor appears only in rotting specimens.
Ivory woodwax
Faint mushroomy smell, mildly pleasant. Some sources describe a hint of almond or resin. Taste bland, mild.
