Mushroom fibrosis and its varieties

The fibril fungus is an inedible representative of the spider line, or cortinaria family. It is an agaricomycete. The name was given due to the fibrous structure of the mushroom leg.

Mushroom fibrosis and its varieties

General botanical characteristic

Mushrooms belonging to the genus fibroblasts have hat-cutaneous fruiting bodies. The shape of the Mushroom Hat is conical or bell-shaped. In the central part, a tubercle is often present. The surface structure is fibrous, silky, in some instances it is covered with scales, sometimes radially cracked.

Many varieties contain a large amount of muscarine alkaloids in the chemical composition, and also have a hallucinogenic effect due to psilocybin, which is part of the chemical composition of the alkaloid.

The mushroom leg is silky in structure, often covered with scales. The color is pale brown or brown.

The fiberglass combines about 150 species growing in forests on soil and among grasslands. About 100 species grow in Russia. The most famous:

  • earthen,
  • Patuillard
  • sharp
  • whitening
  • blushing
  • blue

Earthen fiber

Earthen fiber - a toxic representative of the genus, containing muscarine in the chemical composition.

The mushroom cap grows to 1-3 cm in diameter. The form is initially conical, then open. When ripening, a tubercle forms in the central part. The surface is silky, the structure is fibrous. The color is initially white, after a lapse of time it becomes light pink or light purple, sometimes yellowish. Cracked edges.

The geographic distribution of earthen fibrils covers the European part of Russia, the Caucasus Far East. It occurs in the North American and North African regions, in East Asia and Western Europe.

The mushroom leg grows 2-5 cm long, 0.2-0.5 cm thick. In structure, it is dense in young specimens and hollow in adults. The shape is straight, without characteristic thickenings at the base, longitudinally fibrous. The upper part is covered with powdery coating. The color is closer to white, with time it darkens to brown.

Mushroom pulp has a faint earthy smell and an unpleasant aftertaste, thin and brittle.

It grows singly or in groups in different types of forests, mainly in deciduous. Often found on the edges of roads. It is able to form mycorrhiza with pine roots.

Sharp fiberglass

The sharp fiberglass is a poisonous mushroom with a hat of 1-3.5 cm in diameter with a bell-shaped appearance, eventually acquiring a flat-convex shape with a distinctly central tubercle. Color in shades of brown.

Sharp fiber is prevalent mainly in Europe, is found in Eastern Siberia. Grows in wetlands, sometimes on peat mosses.

Mushroom stalk 2-4 cm long and 0.2-0.5 cm thick, in the shape of a cylinder. The color is similar to the color of the hat. The upper part is covered with plaque.

The flesh of the color is closer to white; when it comes into contact with air, the shade does not change.

Fiberwoman of Patuillard

Mushroom fiberglass is deadly

The Patuillard fiberglass is a deadly spider web representative. The mushroom hat has a white or gray color; in mature specimens it becomes reddish or red-brick. The diameter is 3–9 cm. The shape is initially in the form of a cone, then becomes flat, but a tubercle remains in the central part. The surface is smooth, has a silky sheen. The edges are dotted with radial cracks.

The amount of muscarine contained in Patuillard is 20-25 times higher than the proportion of the poisonous substance in the composition of red fly agaric.

The Patuillard fiberglass grows in park and garden areas, deciduous, mixed and coniferous forests. Prefers limestones and clay soil. It is able to form mycorrhiza with beech and linden roots.

Mushroom flesh without a characteristic odor, has a pepper flavor, white in color. Under mechanical action, it acquires a red color, especially in overripe mushrooms.

The geographical distribution of Patuyara covers individual regions of Asia and Europe. She is often met in the Caucasus.

Mushroom leg 4-10 cm long, 0.8-1.5 cm thick. The color is similar to the color of the hat or lighter. The structure is dense. The shape is cylindrical, thickens to the base. The fungus has a fibrous surface and grooves.

Blushing fiberglass

Blushing fiberglass is among the deadly poisonous representatives.

Her hat grows to 6-9 cm in diameter. As with most representatives of this genus, the shape of the cap is initially bell-shaped, then it straightens, keeping the tubercle in the center. The color of the mushroom cap in young specimens is whitish, with time changes to reddish or yellowish.

The lethal dose of fresh blushing fibrils is 10-80 g.

The mushroom pulp has an alcohol smell and an unpleasant aftertaste. Mushroom leg up to 7 cm long, 0.5-1 m thick. The structure is dense. The color is similar to the color of the hat.

The preferred growth sites are coniferous and deciduous forests.

Whitening fiberglass

Whitening fiber is a toxic representative of the genus. The diameter of the mushroom cap is 1.5-6 cm. The view is convex or conical, with a whitish tubercle in the center.

Mushroom leg 3-10 cm long, 0.4-0.7 cm thick, in the shape of a cylinder. The structure is continuous. The color is whitish pink. The upper part is covered with powdery coating.

Rare view. Distribution geography covers the territory of Kazakhstan.

Mushroom flesh is closer to white in color. It is fragile in structure, has a soft aftertaste and a pleasant smell.

Grows in large groups in pine forests on coniferous litter.

The fiberglass is blue

Blue or blue-green fibril is a member of the family that has hallucinogenic effects due to the psilocybin that is part of the chemical composition. The fungus is conditionally edible after prolonged boiling.

Mushroom hat 1-4.5 cm in diameter. Classical bell-shaped form, subsequently prostrate. The edges are twisting, cracking. The surface is silky, smooth in the central part, fibrous closer to the edges, covered with scales.

The geography of distribution of the blue-green variety covers the European temperate zone.

Mushroom pulp has a pronounced perfumed soap smell. Mushroom leg 2.5-7 cm long, 0.3-0.7 cm thick. The lower part has a blue-green hue.

The blue variety grows on moist sandstones, capable of forming mycorrhiza with the roots of poplar, linden, aspen, birch, oak. It is found in park and garden areas.


The genus fibrinosa is inedible in most cases. Many of its representatives are poisonous, contain muscarine and psilocybin in the chemical composition.
