Stinky cobweb, Goat's cobweb.
Habitats
The goat's web mushroom can be found in mixed and coniferous forests, especially often near pine trees. The fungus prefers moist places covered with moss.
Features of growth
The period in which this mushroom can be found is from mid-June to October.
hat
The cap is quite large, its diameter usually varies from 6 to 12 centimeters. The shape of the cap of young mushrooms is regular, round, the edges are tucked. In adult mushrooms, the edges open up, but the center remains convex. The surface is velvety, dry. The color is violet-gray, very rich. In young mushrooms it is rather purple, but then becomes more bluish. The plates are adherent and frequent. In young specimens they are almost the same color as the cap, but rust as the spores mature. In young mushrooms, the plates are also tightly covered with a cobwebby blanket purple, which is easy to distinguish. The spore powder is rusty brown.
Leg
Young mushrooms have short and thick stems, with a tuberous thickening at the base. With age, the leg acquires a cylindrical shape. Its height is on average from 6 to 10 centimeters, and its diameter is from 1 to 3 centimeters. The color of the leg is the same as that of the cap, but slightly noticeably lighter. It is also covered with the remains of a purple blanket, on which ripening spores scatter. Due to the spores, red stripes and spots appear on the leg.
Pulp
The goat's web mushroom has very thick grayish-purple flesh. It smells very unpleasant - something chemical. To some, the smell resembles that of a goat, which is where the name of the mushroom comes from.
Edibility
Not all sources of the goat's web mushroom are classified as poisonous. But it is definitely not used as food - the disgusting smell will not make anyone want to use it in cooking. It is worth noting that the smell becomes much stronger after cooking.
Etymology of the specific epithet
Traganus, a, um goat, goat. From tragus, i, goat + -anus, a, um, quality.

Other names: Stinking cobweb.
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 synonymized the one described by Schäffer (1882 – 1944) Agaricus amethystinus With A. traganus, and not with what is literally described 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, revealing contrasting rusty-brown flesh; the color is lilac, silver-blue, and may fade to grayish or silver-white, sometimes with a pale ocher tint.
The plates are adherent, from brownish-yellow to grayish-brown, becoming brown with a lighter edge in old age. When young they are covered with arachnoid cortina 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 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, widespread throughout the boreal zone. Found in coniferous forests with the participation of spruce ( Picea) and pine ( Pinus) Worldwide. Common in mixed dark coniferous taiga forests, including almost pure pine 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 view with a similar habit and smell; associated with birch, practically different in appearance complete absence purple 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 confined to birch, but in mixed forests these species can grow together; It is distinguished by less strong, more faded, whitish or lilac flesh without pronounced brown tones, white velum and the absence of a pronounced odor.
- odorous cobweb ( Cortinarius venustus Karst.), synonym C. calopus, is another common inhabitant of the dark coniferous forests of 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) - a peculiar species, distinguished by a much darker dirty purple color throughout fruiting body and the absence of a pronounced pungent odor.

or goat's web (goat's web), smelly
- inedible mushroom
✎ Affiliation and generic characteristics
Or - goat's web (goat's web), smelly(lat. Cortinarius traganus) is a common inedible species of the subgenus sericeocybe (lat. Sericeocybe) and the genus cobweb (lat. Cortinarius), from the family of the same name (cortinariaceae) (lat. Cortinariaceae), order agaricaceae (lamellae) (lat. Agaricales) .
The lilac thick-legged cobweb received its name, like all cobweb mushrooms, for a kind of “cobwebby” cover, in the form of a veil-like film that connects the edges of the cap of young mushrooms with their stem; the epithets “lilac” - for the lilac coloring of the fruiting body, “thick-legged” - for the thick and stocky leg, “goat (goat)” and “smelly” - for the pungent aroma of the chemical acetylene emitted by its pulp, which even intensifies during its heat treatment, and the fruit itself becomes poisonous.
For these reasons, the purple thick-legged cobweb is considered an inedible mushroom; it is prohibited to eat it.
✎ Similar species
All spider web mushrooms are very similar to each other in many ways and most of them have a distinct “toadstool” appearance. And even if it is still possible to determine the genus of such mushrooms, perhaps only a specialist can say what species they belong to. This is why it is so necessary to have a perfect understanding of these mushrooms before picking them.
Therefore, all cobwebs that can be eaten, just in case, are best considered conditionally edible mushrooms. Yes, it is unlikely that there will be such a daredevil who would risk eating them in their “raw” form, as is sometimes done with various edible mushrooms.
Based on this, it is necessary to collect and use any spider web mushrooms for food with extreme caution, and for beginners or inexperienced mushroom pickers, it is better to definitely avoid this at first.
Purple thick-legged webweed can be completely confused with the conditionally edible purple cobweb (lat. Cortinarius violaceus), which differs from it in the juicy purple rather than rusty plates of the hymenophore.
It is often confused with the inedible white-violet cobweb (lat. Cortinarius alboviolaceus), but it is much smaller in size and with an abundant cortina (cobweb blanket) of rich color.
But more often, the purple thick-legged webwort is confused with the camphor spiderwort (lat. Cortinarius camphoratus), which is very similar to the purple thick-legged spiderweb, but they are still distinguished by the smell emitted by their flesh: in the purple thick-legged spiderweb it resembles the smell of acetylene, in the camphorous spiderwort it resembles the smell of camphor. But in both species it is powerful and disgusting.
✎ Distribution in nature and seasonality
The purple thick-legged cobweb grows in the same place where all other cobwebs live: in mixed or coniferous forests, forming mycorrhiza with pine. It is very picky about climate and prefers places with high humidity, in moss, near wetlands, usually not in large numbers, distributed in the temperate climate zone.
It can be found in Western Europe (UK, Belgium, Germany, Austria, Switzerland, Denmark, Finland), Eastern Europe(Czech Republic, Slovakia, Hungary, Romania, Poland, Estonia, Lithuania). IN North America and it does not grow in Africa.
In Russia, it is found in Tatarstan, Buryatia, Leningrad, Sverdlovsk, Yaroslavl, Vologda, Murmansk regions and Krasnoyarsk Territory.
The lilac thick-legged spiderwort bears fruit in the warm period, from mid-July to early October.
✎ Brief description and application
The lilac thick-legged cobweb belongs to the numerous section of agaric fungi, so spores for reproduction are located in its plates. The plates are frequent, attached to the stem with a tooth, at first saffron-ocher in color and become rusty-ocher with age. The cap is very dry, fibrous, hemispherical at a young age, and over time it becomes convex or almost flat, pale bluish-violet, a little later whitish or ocher in color. The edges of the cap of young fruits are turned up and the cortina (cobwebby covering) is often not mucous, pale purple in color. The leg is dense and fibrous, club-shaped, with a thickened base and the same color as the cap, and purple bands are usually visible on it. The pulp is grayish-yellowish or yellowish-brownish in color, with a very strong smell of acetylene, and sometimes with a bitter taste.
As an inedible (and low-poisonous when boiled) mushroom, the lilac thick-legged cobweb is understandably not used for food.
Written by Nikolay Budnik and Elena Mekk.
Goatweed (goatweed, stinky) is named so in the literature because of its smell; you can often read that it smells like goat or acetylene. But in our forests of Uloma Zheleznaya, this mushroom smells like caramel and has a confectionery smell. When we discovered this discrepancy between the book description and reality, we were surprised and began asking advanced mushroom pickers. It turned out that we were not the only ones who discovered this fact.
We encountered this mushroom mainly in coniferous forests among moss. Goat's web is inedible, but not poisonous. Although there is information about the preparation of this mushroom in salted form. And the taste is praised. I'll have to check! In 2017, we pickled this mushroom using a hot method. Not only we liked the taste, but also our friends.
1. We rarely came across goat's web.
2. It can be quite easily distinguished from other spider webs.
3. At a young age, he is all shaggy, as if covered with wool.
4. The shaggy stem remains in more mature mushrooms.
5. The mushroom has a bright purple color.
6. Goat webs may turn a little brown as they age.
7. They are usually found in small groups.
8. Usually these are families of three or four mushrooms.
9. Goat's web spider prefers mossy places.
10. Usually this is a spruce forest.
11. We also met this mushroom in the spruce-pine forest.
12. Nevertheless, according to our observations, goat’s web can most often be found among Christmas trees.
13. The mushroom is not very large in size.
14. This is the cap of a young mushroom.
15. This is his height.
16. With age, the fungus increases, but not much.
17. This is already a mature specimen.
18. This is the average height of a mushroom.
19. The edges of the cap of the goat's web remain curved inward at any age.
20. The hat is dry in any weather, a little rough.
21. She is purple in color, but sometimes turns a little brown as she ages.
22. The plates are covered with a purple web for a long time.
23. In young mushrooms this web is very powerful.
24. Look at her up close.
25. Then the web breaks,...
26. ...but its remains are often visible along the edge of the cap. Sometimes they take on a rusty color.
27. Plates of medium frequency, clay-colored, characteristic of spider webs.
28. This is how the plates are connected to the leg.
29. The leg of the goat's web is initially completely covered with shaggy hairs.
30. The leg widens downward, and becomes tuberously thick near the ground.
31. Her color is purple, and fades a little with age.
32. This is how the leg joins the ground.
33. Inside it is solid, non-hollow.
34. The clay color on the section of the leg is very characteristic.
35. Some fibrousness is visible inside the stem.
36. The flesh of the goat's web is quite dense and strong.
37. It has a strange smell, although not very strong. Some people perceive this smell as caramel-like.
38. Either because of this smell, or because of the wool, the spider’s web is called goat’s web.
39. Having summarized various data, we decided to taste this mushroom. In 2017, we salted some of these mushrooms.
Video 2017 about goat's web
Belongs to the cobweb family. They also call it stinky or goaty. His Latin name Cortinarius traganus.
Characteristic features of the goat's web
Quite a 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 does not exist at all in 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 a 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 is further enhanced by heat treatment. Moreover, it even becomes poisonous. It is strictly prohibited to eat it.
