Have you heard of such a mushroom as cobweb? And it turns out that it is deadly poisonous! Detailed information you will find in the article.
A photo of the mushroom in question is presented to your attention in the article. The most beautiful cobweb (reddish) is the genus Cobweb, family Cobweb family. People also call it the marsh plant. They should not be eaten either raw or cooked, because the toxins they contain can cause kidney failure. This genus consists of at least 40 species. Some are considered poisonous, some are edible, and some are considered edible. By external signs These mushrooms are quite similar, which is why they are often confused. This suggests that it is better not to collect them without proper knowledge about cobwebs and mushrooms in general. And in order to decide to eat such a mushroom, you need to be 100% sure what type of spider web you found.
Until the 1950s, it was believed that these mushrooms could be eaten. And only as a result of a large number of incidents of poisoning with orange-red cobwebs, and later with beautiful cobwebs, registered in 1957, it was decided to classify these mushrooms as deadly poisonous. These two species are the most toxic.
The width of the cap ranges from 4 to 9 cm, starting from a conical shape, flowing into a flat, prostrate shape, with a tubercle in the center. The outer layer is dry, matte with a velvety and fibrous structure. Color - reddish-orange or reddish-brown, the central part is darker. Does not increase in size upon contact with water.
The plates are planted infrequently, they are wide and thick. At first the color matches the cap, then changes to reddish-brown. Young mushrooms have a cobweb-like cover of yellow-ocher color.
The leg is cylindrical, increasing or tapering at the base, while its length is 60-100 mm and thickness 4-10 mm. On the fibrous coating you can find curved bands of a barely yellow tint.
The pulp is light orange or yellow-brown in color with a bad odor.
The spore trail is reddish-brown in color. Their dimensions are 8-8.5 microns, their shape is wide elliptical or almost spherical, with a warty outer layer. Cheilocystids are practically never found.
The most beautiful spider web - deadly poisonous mushroom, which is found in numerous regions in Europe. In our areas they grow in the central regions, as well as in the northern part. You can see such mushrooms in mountainous areas, on the slopes of hills. They are quite rare.
This mushroom grows most often in oak and old coniferous forests, where light sandy soil is common. Raw spruce forests with green sphagnum mosses are also favorable for growth.
Toxic spores can be dispersed to other areas by air flow and tactile contact. Mycorrhiza forms with spruce.
Fruits from July until the first frost occurs. Near clusters of the most beautiful spiderwort you can find others of this genus.
In our territories you can find up to 40 species of mushrooms of this genus, and only 2 of them are edible. Some of them are so dangerous that they are equated to The vast majority of mushrooms are simply inedible.
Only specialists can find the difference among all these types, which means that it is better to avoid them.
Mountain cobweb is another poisonous mushroom, the consumption of which can be fatal. The width of its cap is 30-80 mm, at first it is convex, and when the mushroom ages, its shape becomes flat, with a flat tubercle located in the central part. The outer layer is dry. The color varies from yellow-brown to reddish-brown. The height of the leg is 40-90 mm, and its width is 10-20 mm. It's narrower at the bottom. The surface of the cap and stem is fibrous.
Edible cobweb is a type of mushroom that can be eaten. His middle name is fatty. Its 50-80 mm cap has a dense, fleshy structure with edges turned toward the ground. Over the course of its life cycle, it acquires a flat, slightly depressed shape. Its color is grayish-white and its surface is moist. The leg has a height of 20-30 mm and a width of 15-20 mm, it is dense, without bends.
Slime cobweb is a conditionally edible mushroom. It should not be confused with the mucous cobweb. The hat has a diameter of 100-120 mm. At first it has a bell-shaped shape, which over time becomes flat with a curved edge. The color of the cap varies between yellowish, brown and brown. The entire mushroom is covered with mucus. The leg reaches 200 mm in length, it resembles a spindle. Its color is white, with a bluish tint. On the stem you can find particles in the form of lumps and rings.
There is another similar deadly poisonous species - the brilliant cobweb. It is quite rare. It is very easy to recognize by its bright yellow cap covered with mucus. Found in coniferous forests.
The beautiful cobweb (a deadly poisonous mushroom, similar species of which were presented to your attention above) can also be confused with some edible mushrooms. These are purple hygrophorus, camphor milkweed and a species of honey fungus - armillaria glubnieva. The main difference between the poisonous mushroom and the honey fungus is the presence of ocher belts and red plates on its stem - in the honey mushroom they are white or light yellow.
What else is known about such a mushroom as the beautiful cobweb? Deadly poisonous which includes the following basic data:
The most beautiful cobweb is a rare, deadly poisonous mushroom that contains a very strong toxin, a complex polypeptide - orellan. It does not lose its toxic properties after processing high temperatures, placing it in a different acidic environment and drying it. Toxicity is greatly reduced only under the influence of ultraviolet and solar radiation. This mushroom contains 7.5 mg of orellanine for every 1 g of dried mushrooms.
Experts believe that in addition to orellanine, mushrooms contain two additional polypeptides - cortinarine A and B, which determine the totality of manifestations in the form of patient complaints. The combined presence of these 3 components was detected only in 2 species of mushrooms of this family: the beautiful cobweb (reddish) and the orange-red.
Thanks to a large number Research has determined that the main organ that is affected by orellanin is the kidneys. Due to its combined effects with metabolites, free radicals arise in the epithelial cells of the kidneys, destruction of cell membranes occurs, suppression of alkaline phosphatase and protein production, as well as damage to the structure of RNA and DNA.
Even a small amount of the product can cause harm to the body. 40 g of freshly picked mushrooms consumed as food can lead to death. That is why, to save your life, it is recommended not to pay attention to the brown-red cobwebs, and not to collect suspicious mushrooms at all.
The clinical picture of orellan syndrome largely depends on personal susceptibility to the toxin. In case of spider web poisoning, there are four stages of the disease.
The particular danger of orellanine poisoning is that symptoms resulting from its entry into the body can appear only after a long time, when it is already too late, and everyone will happily forget about eating mushrooms. There are cases when symptoms appear after 7-14 days. During poisoning, the patient may experience nausea, a huge need to drink, a feeling of dryness and burning in the mouth, vomiting, and pain in the abdominal area. This condition can last from 1 to 2 weeks. If you do not seek help in a timely manner, death is possible. In special cases, when the patient’s condition is very serious, death can occur even 5 months after consuming the poisonous mushroom.
In the case of a short lethal stage, within 2-3 days, acute renal failure is formed with a prolonged oligoanuric stage. Children and the elderly suffer the most from the disease.
If nephropathy persists for quite a long time, then in 30-50% of cases it will be followed by the formation of a chronic form of renal failure.
Cobweb mushrooms (Cortinarius) are mushrooms belonging to the cobweb family (Cortinariaceae) and the order Agaricaceae. Many varieties are popularly called marsh plants.
Cobwebs are mushrooms belonging to the cobweb family and the order Agaricaceae
Mycorrhizal fruit cap-peduncle type body with a hemispherical or conical, convex or flat cap, having a pronounced tubercle and a dryish or mucous, smooth or noticeably felt, sometimes scaly surface of yellow or ocher, orange-terracotta, brownish-brick, dark reddish, brown- brick or purple coloring.
The soft part is relatively fleshy or quite thin, white or ocher-brown, yellow, bluish-violet or olive-green in color, sometimes changing shade when cut. All plates are of accrete or slightly descending type, thin and relatively frequently located, of various colors. The cylindrical or club-shaped leg is characterized by the presence of a tuberous thickening at the base. The spores are ocher and brownish.
The fruiting bodies of mycorrhizal varieties can grow in coniferous forests, as well as not too dense deciduous forests. The varieties are widespread in the temperate climate zone:
The most widespread in our country and in many European countries is P. large, growing mainly in mixed forest zones on sandy soils.
Cobwebs can grow in conifers, as well as not too dense deciduous forests
The taste of the mushroom pulp of edible varieties, as a rule, is not very pronounced, but most often it is bitter. Mushroom aroma is completely absent in many species, and some fruiting bodies have a fairly noticeable smell of garden radish. Used for food purposes with great caution. Most often, fruit bodies are fried, salted and pickled.
It is not possible to distinguish between edible and poisonous species by taste or smell, so it is very important to know the exact description and external characteristics cobwebs, which are most often found in our country.

One of the most common types of mushrooms in the temperate zone is the spider web mushroom. It belongs to the group of conditionally edible mushrooms. The genus Cobweb from the cobweb family of the same name is dangerous because there are poisonous varieties.
The mushroom got its name because of the white “skirt” that falls down the stem and resembles a cobweb. The popular name “Pribolotnik” does not reflect the range of the species, although sometimes it is an absolutely swamp resident. It grows in all types of forests in a variety of soils. This is an autumn genus, with peak growth occurring in late August and early September.
Species of Cobwebs are similar to each other in a number of ways:
The species of cobwebs differ in the color of the stem and cap, and the smell of the pulp. Among them there are both edible and poisonous representatives.
Irina Selyutina (Biologist):
The name of the family Cobwebs was given by the French mycologist and phytopathologist of tropical plants Jean Aime Roger (1900-1979), who proceeded from the specific structure of the private bedspread, consisting of cobweb fibers connecting the edge of the cap with the stem.
Most arachnoids are mycorrhiza-formers, the life processes of which are associated with certain tree species. Among the spider webs there are deadly poisonous specimens. However, there are also useful edible species. However, they are few in number and large practical significance Dont Have. A characteristic feature of the genus Cobweb is the different colors of young and mature specimens, and the presence of a rapidly disappearing purple pigment in many species.
By the way. The genus Cobweb is divided into subgenera that have their own specific characteristics, for example:
The genus includes about 25 species. They differ in taste and degree of safety for humans. Some are listed in the Red Book.
The edible cobweb is characterized by a smooth, dense, whitish-brown leg, in the middle (located in the center) there are remnants of the cortina (private web cover), which disappear with age. The length of the leg is usually 2-3 cm with a thickness of 1.5-2 cm, which sharply distinguishes this species from other representatives of the genus.
It grows under various deciduous trees, but more often under beech and oak. Growth is more group or colonial. Also, adult individuals lack the remains of the veil.
The species of triumphal cobweb is also considered edible. But due to its reduced taste, it should be classified as conditionally edible.
The difference between this group and edibles is that conditionally edibles require pre-processing. They should not be eaten raw; it is not recommended to eat them fried without prior soaking.
This species lives in deciduous forests. They find it under birch and oak trees. Often accompanied by milk mushrooms.
The pulp of this species is odorless and tasteless. Color varies from white to cream. The mushroom is found in coniferous and mixed forests.
Attention! Do not confuse the slimy cobweb species with the slimy cobweb species.
Identifying an inedible species is not easy, so don't risk taking a nice-smelling fruiting body into your basket.
The following types of spider webs are also considered inedible:
Inedible species destroy the kidneys with their toxins, resulting in intoxication of the body.
They are limited to standard indicators for mushrooms. This is the presence of protein, vitamins and microelements in the fruiting bodies. They contain more vitamins A and group B than fruits and vegetables.
Even edible mushrooms contraindicated:
You cannot eat edible mushrooms collected within the city and near busy highways, factories, and the private sector.
Edible spider web mushrooms are considered a delicacy; they have a wonderful nutty taste. Tolstushka is delicious fried or stewed with sour cream or cream. Decoctions from the plum are used to make broth. Edible fruiting bodies are also pickled and dried, but this can result in loss of most taste.
The excellent cobweb is dried or pickled only after long soaking and boiling. Young specimens are suitable for pickling and salting. For your information. The shiny coating on the cap of the purple cobweb species disappears when dried.
Used to obtain probiotics and extract valuable microelements. In industry, dyes are extracted from colored fruiting bodies. The species cannot be used in home medicine.
Taxonomy:Description:
The hat and blanket are slimy. 3-8 cm in diameter, initially convex, then flat, sometimes with a small tubercle, bright blue or bright bluish-violet, then from the center becomes grayish or pale brown, with a bluish or violet edge.
The plates are adherent, sparse, initially bluish or purple, remain that way for a very long time, then light brown.
Spores are 7-9 x 6-8 microns in size, broadly ellipsoidal to almost spherical, warty, yellow-brown.
The leg is slimy and dries out in dry weather. Bluish, bluish-violet, or lilac with ocher-greenish-olive spots, then whitish without bands. Size 6-10 x 1-2 cm, cylindrical or slightly thickened downward, closer to club-shaped.
The pulp is whitish, bluish under the skin of the cap, tasteless and odorless.
Spreading:
Grows in coniferous and deciduous forests, often with high humidity, prefers birch. On soil rich in calcium.
Similarities:
It is very similar to, grows with it and ends up in the baskets of inexperienced mushroom pickers along with the rows. It is similar to Cortinarius transiens, growing in coniferous forests on acidic soils, which is sometimes found in sources as Cortinarius salor ssp. transiens.
Grade:
Not edible.
Note:
Belongs to the subgenus Myxacium, which is characterized by a mucous cap, stalk and general veil. Among similar species, it belongs to the section Delibui (Cortinarius delibutus), which combines mushrooms with plates in bluish-violet tones.
Spider web is not the most common mushroom. Its family includes almost 40 species. Novice mushroom pickers sometimes confuse cobwebs with other mushrooms and throw them into a basket, without thinking that they can be deadly. Cobwebs come in a wide variety of shapes and colors. The names of the types of mushrooms speak for themselves: orange cobweb, crimson, white-violet, etc.
The cobweb family got its name from the cobweb-like cover that connects the stem of the mushroom to the cap. It is especially noticeable in young mushrooms. In more mature members of the family, the cobweb encircles the lower part of the leg with a porous ring. All varieties of this mushroom have a round cap., which becomes more and more flat as it grows. Its surface has a smooth or scaly texture and can be either slippery or completely dry.
The stem and surface of the mushroom cap have almost the same color. The standard shape of the leg is cylindrical, but in some species it has a thickened base. The flesh of the mushroom is usually white, but can also be colored. The cobweb family loves moisture very much. They are most often found near wetlands, which is why they have earned the nickname “swamplanders.”
Mushrooms of this family are common in the European part of Russia, but they are quite difficult to find. Some species of cobwebs are listed in the Red Book. Spider webs rarely grow alone. Usually these are clans of 10 to 30 pieces, clustered in damp lowlands. It is recommended to collect them from late summer until the first frost.
The most special one is the most poisonous spider web. To avoid being hit fatally dangerous mushroom to cart, you need to find out more about it. The cap of an adult beautiful mushroom reaches a diameter of up to 10 cm. In young mushrooms it can be in the form of a cone. As the mushroom grows, the cap changes its appearance and acquires a flat-convex shape with a blunt tubercle in the center. The surface is dry, velvety, slightly scaly at the edges. The color of the cap can range from red-brown to ocher-brown.
The stem of an adult mushroom reaches 12 cm in length and 1.5 cm in width, it slightly widens towards the base and is covered with noticeable bracelets of a spider web. The surface is orange-brown, fibrous. The flesh of the mushroom is yellow-ochre, without taste. Sometimes has a faint radish odor.
The most special grows in coniferous and mixed wet forests in the north of the European part of our country. Contains slow-acting orellanine toxins, which cause severe renal failure with possible death.
Typical symptoms of spider web poisoning are: vomiting, a feeling of dry mouth, constant thirst, cramping abdominal pain. If these symptoms occur after eating a mushroom, you should immediately call a doctor. Transporting a patient with suspected mushroom poisoning on your own is dangerous, because some toxins affect the functioning of the heart. While waiting for the ambulance to arrive, you must:
