Poisonous mushrooms of Ukraine: photos, names, and key signs

Safe foraging starts not with which mushrooms to pick, but with which ones to leave. Most poisonings come down to a handful of well-known species, and knowing them “by sight” matters even if you confidently gather your favorite mushrooms. After all, a dangerous lookalike often grows right next to the find you were hoping for.

We've gathered the main poisonous mushrooms of Ukraine: their names, telltale signs and the edible species they're most often mistaken for. This isn't a complete identification key, but a guide to help you keep trouble out of your basket.

The most dangerous: the death cap and amanitas

Most fatal poisonings are caused by mushrooms of the genus Amanita.

• **Death cap.** The most poisonous mushroom in Ukraine. A pale green or olive cap, white gills, a skirt on the stem and a sac at the base. It isn't bitter and tastes pleasant, which is exactly what makes it so treacherous. We've devoted a separate in-depth article to it.
• **Destroying angel.** Entirely white, with an unpleasant smell, and deadly poisonous. Its white color is deceptively similar to a field mushroom.
• **Panther cap.** A brownish cap with white spots. Highly poisonous, more dangerous than the fly agaric.
• **Fly agaric.** The classic fairy-tale mushroom. Poisonous, though deaths are rare.

We cover the whole family in our article on the amanitas of Ukraine. The shared warning sign: a skirt on the stem and a sac or swelling at its base.

Treacherous poisonous species among “ordinary” mushrooms

Not all poisonous mushrooms are brightly colored. Some disguise themselves as everyday edible species.

• **Brown rollrim.** It used to be salted in huge quantities, but now it's on the poisonous list: its toxin builds up in the body. A brown funnel-shaped cap with an inrolled margin. More in a separate article.
• **False morel.** A spring mushroom with a brain-like brown cap. It contains a dangerous toxin, so picking it is not recommended.
• **False honey fungus.** They grow on stumps right next to the real thing. We explain how to tell them apart in our article on false honey fungus.
• **Sickener.** A bright red, acrid brittlegill that causes digestive upset.

Inedible and bitter species that spoil your basket

A separate group of mushrooms isn't deadly, but is inedible or so bitter it ruins the whole dish.

• **Bitter bolete.** Also called the bile bolete, a porcini lookalike. Not poisonous, but so bitter that one is enough to ruin a whole pot. To learn how to tell it apart, see our comparison of porcini and the bitter bolete.
• **Devil's bolete.** A bolete with reddish pores that turns blue when cut. Poisonous, though not deadly.

These mushrooms won't kill you, but a single specimen can spoil your whole basket, so they're worth knowing too.

How to stay safe

A few simple habits will bring the risk down to almost nothing.

1. Only pick mushrooms you know well. If in doubt, leave it out. This is the golden rule.
2. Check the base of the stem. A sac or swelling at the bottom is a reason to be on guard.
3. Don't taste raw mushrooms. Taste does not reveal poison.
4. Learn them one at a time. Expand your list of known species gradually.

We've collected the full set of guidelines in our safe foraging rules, and the other side of the coin, reliable edible species, in our guide to the edible mushrooms of Ukraine. If poisoning does happen, call 112 or your local emergency number immediately and follow our first aid instructions.
