Patouillard fiber grows in coniferous and deciduous forests. It appears from May to October, especially abundantly – in August and September, in those places where mushrooms, ringed caps and other edible mushrooms grow.
The cap is 6-9 cm in ∅, first bell-shaped, then prostrate, with a tubercle in the center, cracks in old age, whitish in young mushrooms, then reddish, straw-yellow.
The pulp is white at first, then reddish, with an alcoholic smell and an unpleasant taste.
The plates are wide, frequent, adherent to the stem, first white, then sulfur-yellow, pink. Brown with reddish spots in old age. The spore powder is ocher-brown. Spores are ovoid, slightly reniform.
Leg up to 7 cm in length, 0.5-1.0 cm ∅, dense, slightly swollen at the base, the same color as the cap.
The fungus Fiber patuya is deadly poisonous.
Muscarine poison in it is 20 times more than in the red fly agaric. Fiber patuyard affects the autonomic nervous system. Symptoms of poisoning appear 20-25 minutes after eating. Signs of poisoning: increased blood pressure, headache, dizziness, nausea, trembling limbs, slowing down of cardiovascular activity. Lethal dose of fresh mushroom 10-80 g.
