Paxillus involutus stands out in mycology for its deceptive edibility—once consumed in Europe but now avoided due to toxins triggering immune responses. Its brown, funnel-like cap with rolled rims and bruising gills make it identifiable in woodlands, where it forms symbiotic ties with birches and pines, aiding nutrient exchange while thriving in acidic soils.
Amanita phalloides, known as the death cap, is the deadliest mushroom worldwide, responsible for 90% of fatal poisonings. It resembles edible species, grows with broadleaved trees, and is found across many continents. Its toxins resist cooking and freezing; just half a cap can kill an adult.
Agaricus xanthodermus is notorious for causing most mushroom poisonings in regions where it grows. Its vivid yellow staining and strong ink-like odor are key for distinguishing it from edible champignons.
Known for its striking, massive appearance and red pores, the Devil’s Bolete emits an unpleasant odor and is highly poisonous, causing severe gastroenteritis if ingested.
