Goat's web whether edible or not has a strong smell. Home encyclopedia

Goat's web, or stinking (lat. Cortinarius traganus) - inedible mushroom genus Gossamer Inedible mushroom. Goat's web is found in coniferous and mixed forests usually with pine; like many spider webs growing in similar conditions, it prefers moist, mossy places, in forest shelter belts, often in large groups. These mushrooms grow from mid-June to early October.

Goat's web is inedible due to the unpleasant odor of acetylene. It is worth noting that during the cooking process this smell intensifies several times. In some sources, goat spider webs are generally classified as poisonous species.

Massive caps 3-12 cm, at first, spherical and lilac, then hemispherical and, finally, open ocher, with a fringed edge. The shape of the cap of a young mushroom is regular, round with tucked edges, then over time it opens up, leaving a bulge in the center. The surface of the goat's web is velvety and dry. Its color is rich - violet-gray, while in youth it is more violet, and then more gray. The plates are ocher-yellow with a violet tint, later brownish-ocher.

The pulp of young mushrooms is very thick, white-blue, then ocher or grayish-violet. The pulp emits a very strong bad smell, as described by many, it is chemical-like and resembles acetylene or goat, which is where the name comes from.

The plates of the fungus are adherent and frequent. In young specimens they are close in color to the cap, but quickly become brownish-rusty, and as they grow their arrangement becomes more dense. In young mushrooms, the plates are tightly closed with a noticeable cobwebby cover. The color of the bedspread is purple. Frequent, adherent, at the very beginning of development the color is close to the cap, but very soon their color changes to brownish-rusty, only thickening as the mushroom grows. In young specimens, the plates are tightly covered with a well-defined cobwebby cover of a beautiful purple. Spore powder is rusty brown in color.

The legs of young spider webs are short and thick, with a tuberous thickening observed in the lower part. As it grows, the stalk soon becomes cylindrical. Its height is 6-10 centimeters, and its diameter is 1-3 centimeters. The color of the leg is close to the cap, but lighter. The stem is covered with purple remains of the veil, on which ripening spores are scattered. Due to the spores, red stripes and spots appear on the leg. In youth it is thick and short, with a massive tuberous thickening; as it develops, it gradually becomes cylindrical and smooth.

There are a lot of purple web spiders. The goat's web spider is reliably distinguished from the rare Cortinarius violaceus by its rusty (not purple) plates, from the white-violet web spider (Cortinarius alboviolaceus) by its rich color and brighter and more abundant cortina, from many other similar but not so well-known blue spider webs by its powerful disgusting odor. The most difficult thing is probably to distinguish Cortinarius traganus from the closely related and similar camphor web spider (Cortinarius camphoratus). That one also smells strong and unpleasant, but more like camphor than goat.

Separately, it should be said about the differences between the goat's web and the purple rower (Lepista nuda). They say some people are confused. So if your row has a cobwebby cover, the plates are rusty-brown, and it smells loud and disgusting, think about it - what if something is wrong here?

The goat's web has no poisonous counterparts.

Gossamer's web, or smelly(lat. Cortinarius traganus) - an inedible mushroom of the genus Cobweb (lat. Cortinarius).

Goat's web cap:
Quite large (6-12 cm in diameter), regular round shape, in young mushrooms hemispherical or cushion-shaped, with neatly tucked edges, then gradually opens, maintaining a smooth convexity in the center. The surface is dry, velvety, the color is rich violet-gray, in youth it is closer to violet, with age it tends more toward glaucous. The pulp is very thick, grayish-purple, with a very strong unpleasant (and according to many, disgusting) “chemical” odor, reminiscent, according to many, of acetylene or an ordinary goat.

Records:
Frequent, adherent, at the very beginning of development the color is close to the cap, but very soon their color changes to brownish-rusty, only thickening as the mushroom grows. In young specimens, the plates are tightly covered with a well-defined cobwebby cover of a beautiful purple color.

Spore powder:
Rust brown.

Goat web spider leg:
In youth, thick and short, with a massive tuberous thickening, as it develops it gradually becomes cylindrical and smooth (height 6-10 cm, thickness 1-3 cm); By color scheme close to the cap, but lighter. Abundantly covered with purple remains of cortina, on which, as the ripening spores scatter, beautiful red spots and stripes appear.

Spreading:
Goat's web is found from mid-July to early October in coniferous and mixed forests, usually with pine; like many spider webs growing in similar conditions, it prefers moist, mossy places.

Similar species:
There are a lot of purple ones. The goat's web spider is reliably distinguished from the rare goat's web by its rusty (not purple) plates, from its rich color and brighter and more abundant cortina, from many other similar, but not so well-known blue spider's webs - by its powerful disgusting smell. The most difficult thing is probably to distinguish Cortinarius traganus from the close and similar one. That one also smells strong and unpleasant, but more like camphor than goat.

Edibility:
The mushroom is inedible due to its unappetizing smell, which increases many times during cooking, and is even poisonous.

Notes
I would like to say a huge thank you to the goat's web for letting me understand how and what a goat and acetylene smell like - I have never smelled either of them in my life. And now I don’t really want to.

Goat's web spider (Cortinarius traganus), stinking cobweb, goat's cobweb.

The mushroom is interesting only from a mycological point of view, nutritional value he has no idea. However, the elegant appearance and unusual color of this mushroom attracts attention.

Hat.
With a diameter of up to 4-12 cm, in young mushrooms it is hemispherical, hemispherical, the edges of the cap of young mushrooms are turned up, as the mushroom grows, the cap becomes flat, flat-convex. It is dry, fibrous, fleshy, thick, smooth. The color ranges from pale bluish-violet or lavender, often bright in young mushrooms, to almost off-white, with an ocher tint. The middle of the cap is always a lighter color.

The web (cortina) of the mushroom is abundant, dense, and pale purple in color. The plates of the goat's web spider (Cortinarius traganus) are sparse, thick, wide, adherent, at first yellow-ocher, with a slight purple tint; in old mushrooms they are brown with a rusty tint.

Leg
Up to 6-12 cm in height and 1-3 cm in diameter, club-shaped, strongly thickened at the base, dense, smooth, solid, fibrous. The same color as the cap, lilac, blue-violet, gradually fading to a whitish hue, with remnants of a fibrous web.

Pulp
Light with yellowish, brown, red, rusty veins, dense, hard, with an unpleasant, strong odor of acetylene (goat odor), usually with a pronounced bitter taste.

Where to look.
Goat's web spider (Cortinarius traganus) grows from July to October in the forests different types, preferring proximity to coniferous trees, especially with pine. Very often it can be found in pine forests, among green mosses.

Eating.

Belongs to the cobweb family. They also call it stinky or goaty. Its Latin name is Cortinarius traganus.

Characteristic features of the goat's web

Enough large mushroom. Its cap has a rounded regular shape. In young animals it is cushion-shaped or hemispherical. Then it opens, while maintaining a convexity in the middle. The edges are neatly folded. It is 6-12 centimeters in diameter. Its surface is velvety and dry. Its rich violet-gray color changes with age to just gray.

The flesh of the mushroom is quite thick. Its smell is strong, very unpleasant and even disgusting. It resembles that of a regular goat or the chemical acetylene.

The hymenophore plates are frequent and grow tightly to the stem. They are covered with a cobwebby purple blanket. At first their color is the same as that of the cap. At the end of development it becomes thick and brownish-rusty. Spore powder is brown.

The young mushroom has a short and thick stalk. Its tuberous thickening is quite massive. As it develops, it becomes smooth and acquires a cylindrical shape. Her maximum height 10 centimeters and a thickness of 3 centimeters. The color scheme is similar to the one on the hat. In addition, the stem is covered with beautiful red stripes and spots.

Fruiting of the goat's web begins in mid-July and ends in early October. It can be found in mixed or coniferous forests. It forms mycorrhiza with pine. Picky, prefers places with high humidity and overgrown with moss.

Widely distributed in Russia and such European countries, like England, Switzerland, Lithuania, Estonia, Czech Republic and others. Due to the unsuitable climate, it is not available at all. North America and Africa.

Similarities with other species

There are many cobwebs in nature. One of them, Cortinarius violaceus, is a common edible specimen. It is quite rare. It differs from the goat variety by the purple rather than rusty plates of the fruiting body. But Cortinarius alboviolaceus is characterized by abundant cortina of bright, rich color. The most difficult option is camphor mushroom. It is almost the same and its smell is powerful and disgusting. For a number of reasons, goat's web is considered inedible. Its terrible smell intensifies even more when heat treatment. Moreover, it even becomes poisonous. It is strictly prohibited to eat it.

Taxonomy

The first description of this species under the name Agaricus traganus made by Elias Magnus Fries (1794 - 1878) in the second volume of Mycological Observations in 1818.

Interesting fact: in 1821, in his famous work The “mycological system” Frieze is synonymous with that described by Schäffer (Julius Schäffer; 1882 – 1944) Agaricus amethystinus With A. traganus, and not with what is described literally on the next page A. camphoratus(in modern interpretation - camphor cobweb ( Cortinarius camphoratus)).

Habit

hat

The cap is 40–100 mm in diameter, at first hemispherical, when ripe it opens to a convex shape, sometimes with a distinct wide tubercle in the center. The surface is matte, silky, silky-fibrous, when drying out and after rains following a period of dry weather, it can crack into more or less large scales, exposing contrasting rusty-brown flesh; the color is lilac, silver-blue, and may fade to grayish or silvery-white, sometimes with a pale ocher tint.

The plates are adherent, from brownish-yellow to grayish-brown, brown with a lighter edge in old age. IN at a young age covered with cobwebby cortina of lilac color.

Leg

The leg is 50–100 mm high, 8–20 mm in diameter, powerful, strong, usually club-shaped, but without a pronounced bulb, grayish-lilac, lilac, partially covered with velum forming felt belts.

Velum

The velum is abundant, cobwebby or even cotton wool-like, lilac in color, preserved in the form of individual fibers on the surface of the cap and flakes along the edge of the cap and on the stalk, where they form more or less pronounced belts.

Pulp

The flesh is characteristically rich yellow-brown, red or grayish-brown in color, sometimes with lilac marbling in the upper part of the stem. The smell is bright and characteristic, sweet and sour, sometimes cloying; the taste is strong, bitter, unpleasant.

Chemical reactions

Guaiac resin gives a yellow-green color reaction; phenol - red.

Microscopy

Spores 8 – 10 × 5 – 6 µm, ellipsoidal, almond-shaped, moderately or slightly warty.

Basidia 23 – 30 × 7.5 – 8.5 µm, cylindrical or swollen, 4-spores, with a buckle at the base.

The edge of the plate with small cylindrical sterile cells 20 – 30 × 3 – 5.5 µm.

There are no preurocystids.

Pileipellis consists of hyphae 3–7 µm in diameter. Hyphae are hyaline or with yellowish intracellular pigment.

The hypodermis is poorly developed, consisting of more or less hyaline hyphae up to 20 µm in diameter.

Partitions with buckles.

Ecology and distribution

A common species, widely distributed throughout the boreal zone. Found in coniferous forests featuring spruce ( Picea) and pine ( Pinus) around the world. Common in mixed dark conifers taiga forests, including almost pure cedar trees ( Pinus sibirica). In pure pine forests the form is found S. traganus f. ochraceus, almost completely devoid of purple shades in color.

Fruiting

July – September.

Nutritional properties

Similar species

• Camphor cobweb ( Cortinarius camphoratus(Fr.) Fr.) is a very similar species, found in the same habitats, but generally preferring somewhat damper places; similar in habit, lilac color of the stem and cap, but generally differs in the lighter, lilac-silver color of the fruiting bodies, lighter pulp with a predominance of lilac rather than brown tones, and a sharper, chemical odor.
• Gossamer white gossamer ( Cortinarius niveotraganus Kytöv., Niskanen & Liimat.) – rare species with a similar habit and smell; associated with birch, practically different in appearance complete absence violet tones in color, with the exception of young plates and marbling in the pulp of young fruiting bodies; its fruiting bodies are painted fawn, and the flesh is less bright and yellow than C. traganus and its pale-colored form f. ochraceus.
• White-violet cobweb ((Pers.) Fr.) is associated with birch, but in mixed forests these species can grow together; It is distinguished by less strong, more faded, whitish or lilac pulp without pronounced brown tones, white velum and the absence of a pronounced odor.
• odorous cobweb ( Cortinarius venustus Karst.), synonym C. calopus, - another common inhabitant of dark coniferous forests Western Siberia. This is an elegant, peculiar small mushroom, which, nevertheless, is similar to the goat's web with violet tones in color, fragrant pulp and abundant velum. It is distinguished by a much more slender habit and smaller size, usually by contrasting colors of the cap and leg (its cap is fawn in color, and the leg is purple or lilac), as well as characteristic sparse, light-colored plates.
• Gossamer violet ( Cortinarius violaceus(L.) Gray) – peculiar appearance, is distinguished by a much darker dirty purple color of the entire fruiting body and the absence of a pronounced pungent odor.
