Gypsy mushroomCortinarius caperatus

Yes, it is an edible mushroom. But this is not a mushroom for beginners, despite its popularity. Many other Cortinarius are dangerously poisonous (especially C. orellanus and C. rubellus with orellanine — a slow-acting kidney toxin whose effects are delayed by 3-14 days). The key features of the gypsy mushroom specifically: a violet-silvery floury bloom on an ochre-yellow wrinkled cap + a membranous ring on the stem. Without confident identification, do NOT pick ANY Cortinarius.

Clean it and cut it up. You can fry it right away for 15-20 min with onion and cream — the classic way. Or stew it with potatoes. Young (closed) ones are best for pickling and salting. In soups — add toward the end of cooking. Dried gypsy mushroom is a favorite of Carpathian cooking: cut young ones into thick slices, dry at 40-50°C and store in jars. Soak for 30 min before use.

The genus Cortinarius has roughly 2000 species, dozens of which contain orellanine — a slow-acting (3-14 days) toxin that destroys the kidneys. By the time symptoms appear, there is no longer any effective treatment — a kidney transplant is needed. Cortinarius caperatus is considered safe, but confusing it with its dangerous relatives (Cortinarius orellanus, C. rubellus) is a real risk. Hence the rule: pick only mushrooms that have ALL the features of the gypsy mushroom (wrinkled ochre cap with a violet floury bloom + membranous ring on the stem + growing in coniferous/mixed forests of the Carpathians and Polissia).

In coniferous, mixed and deciduous forests — most often with fir, spruce, pine, birch and beech. It loves mossy patches in pine woods, bilberry thickets and forest edges. It forms mycorrhiza. The best finds are on the edges of Carpathian fir forests and in the pine-birch stands of Polissia among the moss. Especially common in pine forests with bilberry.

Mostly the Carpathians (Zakarpattia, Ivano-Frankivsk, Lviv and Chernivtsi regions), the Carpathian foothills, Polissia (Volyn, Rivne and Zhytomyr regions). In the Forest-Steppe and steppe it is rarer or absent. This is a mushroom of the mountain and Polissia coniferous forests.

August — October, peaking in September. It loves a damp, cool autumn with moderate temperatures of +10..+15°C. It does not fruit in the summer heat. It tolerates the first light frosts.

With dangerous Cortinarius — especially C. orellanus and C. rubellus (both containing the slow-acting kidney toxin orellanine): these have an intense orange-brick cap with no wrinkles and no violet bloom. With young Agaricus mushrooms — these have pink/brown gills, while the gypsy mushroom's are clay-ochre. With webcaps of other species — there are dozens of them; don't pick any without confident identification.

Four features together: (1) the cap is ochre-yellow and wrinkled, with a violet-silvery floury bloom in young mushrooms; (2) the gills are clay-ochre in mature mushrooms; (3) the stem has a membranous ring; (4) it grows in coniferous or mixed forests of the Carpathians/Polissia, among moss. If all four match, it is Cortinarius caperatus. If even one doesn't match, don't pick it.
