White mushroom head (Coprinus comatus) has a white, fleshy, ovoid-shaped, covered with a blanket, and the cover is subsequently torn apart. The bonnet of this plate-shaped fungus is up to 10 cm in diameter, bell-shaped, white, thin, covered with yellowish scales. The plates are initially white, then pink and black, then spill into a black liquid.
Despite the "tasteless" name, mushrooms can be eaten. True, only at a young age, while their hat plates did not become dark. The name of the guinea-pigs got through the places of growth - most often these gifts of the forest can be found in meadows and pastures with rich humus soil.
