Fool's webcapCortinarius orellanus

Because of its unique 2-21-day delay of symptoms. The death cap kills within 4-5 days — there is at least a chance of quick help. The fool's webcap is slow: symptoms come a week or two later, the person has already forgotten about the mushroom, and by then the kidneys are badly damaged. There is no antidote. Fatality rate up to 15%; survivors often need lifelong hemodialysis. This isn't a "scare story" — there are documented cases of mass poisonings in Poland (1957, 102 people, 19 deaths), Scotland and France.

Four features together. (1) Cap color: orange-red, russet fiery orange. (2) Gill color: russet-orange in young mushrooms, rusty brown in mature ones. (3) Cobwebby cortina: in young mushrooms — fine white or yellowish fibers between the cap margin and the stem. In old ones — a band of rusty-brown spores on the stem. (4) Rusty-brown spore print: a print on paper within 6-12 hours. Any russet gilled forest mushroom with a cobwebby cortina is a suspected carrier of a deadly toxin. We don't take it.

See a doctor IMMEDIATELY, even without symptoms. Say: "suspected webcap with orellanine, ate mushrooms between 2 days and 3 weeks ago". The doctor will order kidney function tests (creatinine, urea, electrolytes), forced diuresis, and hemodialysis if creatinine rises. Time is critical: the first 24-48 hours after eating give the best chance of full recovery. Keep any remains of the mushroom — anything: the cap, soil from where it was found, photos. Testing for orellanine is available in specialized laboratories.

No, they're safe. The toxins act only when swallowed (eaten). You can touch the mushroom with your hands, photograph it, carry it out of the forest. Just don't eat it and don't "test it on your tongue" — serious poisonings from a single tiny taste have been described. Washing your hands after the outing is standard hygiene and never a bad idea.

In deciduous and mixed forests — mainly with oak and beech, less often with birch. It likes mossy patches, forest edges and shady slopes. It isn't fussy about soil type.

Throughout the forest and forest-steppe zones: the Carpathians, the Carpathian foothills, Polissia, the forest-steppe. In the steppe — in floodplain oak woods. Not abundant, but consistently present — this isn't "some exotic species from the Alps", it's our local mushroom, one you can come across on an ordinary mushroom-picking trip.

Rather — "when to recognize it and pass it by". August — October, peaking in September. Its season coincides with the main mushroom season, so the risk of confusion is highest in September.

With other russet webcaps — C. rubellus (deadly webcap), also deadly. With Gymnopilus species (rustgills) — bitter, inedible, on conifer wood. With a young chanterelle (Cantharellus cibarius) — edible, but it has ridges on the underside, not gills, and a characteristic fruity apricot smell. With a young Galerina — also deadly, but on stumps. Our firm advice: gilled mushrooms with a rusty-brown spore print and an orange cap — we NEVER take them.

Just walking — no, there's no need. The mushroom doesn't "jump into your basket" or give off anything. You only need to worry if you are picking mushrooms and unfamiliar russet gilled species have ended up in your basket. For ordinary forest walks this species poses no danger — it's simply a fact worth knowing, so you can make sure your foraging relies on 100% identified species.
