It should also be noted that in some sources Boletus quercicola (Boletus quercicola) is distinguished as separate species White oak mushroom. Inexperienced mushroom pickers may confuse it with, which is distinguished by a black mesh on the stalk and a pinkish hymenophore. However, it is unlikely to intersect with this form of white, since it is an inhabitant of coniferous forests.

Note:
The porcini mushroom has long been famous for its medicinal properties. Even in Rus', they were used to treat frostbite and ulcers, and tuberculosis. Hercinin, which is a good support for the heart, has been isolated from the mushroom. There is information about the anti-cancer effect of the fungus. In any case, it is useful to eat raw porcini mushrooms in various salads.

The reticulated boletus is an inveterate inhabitant of forests. The mushroom belongs to the Boletaceae family, the boletus genus.

Without a doubt, it can be cut and placed in a basket, since it is edible. Very often, mushroom pickers consider the reticulated boletus to be a variety of porcini mushroom. But this is a separate species with excellent properties.

Appears mainly in summer time, therefore earning the name “White Summer Mushroom”. It grows mainly in oak groves and deciduous forests.

How not to confuse boletus reticulum with other types of mushrooms? What are its main features?

Description of the Reticulated Boletus

In order to recognize the reticulated boletus in the forest, you need to have an idea of ​​its appearance. From Latin - . For many, the familiar name is Porcini mushroom Oak or Net form.

Boletus reticulum, White summer mushroom, White mushroom reticulated form.

The mushroom cap is quite large. Its diameter ranges from 8 to 25 cm, depending on the age of the mushroom, as well as the conditions in which it grows.

In some cases, with well-established external factors, namely weather and a good location, the mushroom cap can grow up to 30-35 cm.

It is covered with a weak velvety skin, pleasant to the touch. Droplets of moisture collect on it.

If the summer is excessively dry, hot, and the mushroom grows in a clearing open to sunlight, then the texture of the cap begins to crack. A grid pattern appears. Small insects find their refuge there.

As for the color of the cap, it changes depending on the location of the mushroom growth. There are dark brown, gray-brown, coffee and ocher colors. Sometimes, with a lack nutrients White spots appear on the mushroom cap, which can grow over time.

If you look under the cap, you can see very thin, almost transparent tubes that do not connect to each other.

Their edges have a white tint, but what older mushroom, the darker the tubes become. Colors can vary from yellow-orange to green. The spores have a yellow or orange tint, less often brown.

The spore powder is brownish or olive in color.

The hat does not fit tightly on the stem and can fall off with the slightest careless movement.

The spores are spindle-shaped, brown or honey-yellow in color. They have a smooth surface. Spore size is 13-20 x 4-6 microns. The spore powder is olive-brown in color.

The stem of this mushroom can reach a length of 10 to 25 cm. The diameter also varies from 2 to 8 cm. In most cases, a cylindrical shape of the stem is observed, however, with age it thins out at the cap and grows at the roots.

The color of the stem of young mushrooms is white, while that of older mushrooms has a light nutty tone. It has a brown mesh on it.

The flesh of the stem of this mushroom is quite dense, however, the older the mushroom, the more spongy its texture.

How do you know if a mushroom is suitable for consumption? This is checked by the leg. To do this, you need to press well on it. If the leg is springy, this means that the mushroom is edible.

Even in an old mushroom, when cut, the flesh has a white tint. Even in the open air its color does not change.

Deep under the tubular layer, the flesh may also have a yellowish tint.

It has its own peculiar pleasant mushroom smell. Has a sweet taste.

Habitat

This mushroom can be classified as an early emerging species. That is why you can find the first white reticulated boletus mushrooms in May. Carefully monitor their location, as mushrooms may appear in the mycelium even before October.

Basically, white oak mushroom is concentrated in deciduous forests. Prefers to appear under linden, beech, oak and chestnut trees.

Mushrooms will not appear in cold climates, they are hobbyists high temperatures, moderate moisture.

They are mostly found in hilly or mountainous areas. Can often be found in middle lane Russia.

The stem of the white oak mushroom is from 10 to 25 cm in height, 20 to 70 mm in width. In young mushrooms, the stem is club-shaped, in adulthood it has a cylindrical shape. The surface of the stem is light brown or light coffee color. Covered along the entire length with a clearly visible white or brownish mesh on a light walnut background.

The flesh of the mushroom cap is different from the stem. It does not have a sweet taste, rather a little salty. The pulp separates easily and has a white tint. Older mushrooms are yellowish, with small inclusions. Has a characteristic mushroom smell.

After boiling, the pulp becomes soft and cutlery literally sinks into it.

When pressed, good flesh should spring back, but if this does not happen, the mushroom is either too old or lacks moisture, as a result of which the taste properties could be damaged.

Fruiting period

You can start looking for mushrooms in mid-May, when the frosts pass and the sun begins to appear. Boletus mushrooms appear very quickly, so literally a few days after settled sunny weather, you can go searching. Most big number mushrooms occur in June-July.

But in August - September and even early October there are fewer mushrooms, but still, they appear in forest clearings where the sun is active.

Where does it grow and when to collect Boletus reticulum?

The most active growth of mushrooms can be seen in clearings illuminated by the sun and in deciduous forests.

The reticulated boletus loves the sun's rays.

Loves deciduous and mixed forests. Can often be found on the edges of the forest.

Very often included in mycorrhiza with beech, oak and hornbeam.

Most common in the Belgorod region, Crimea, Stavropol and Krasnodar region. Found in the Caspian region.

It actively bears fruit from May to October, however, you need to take into account unique climatic conditions a separate area of ​​your residence.

Edibility

This mushroom is considered one of the most delicious and edible boletus. It can be used in food various types, and in any case he is wonderful.

Dried boletus has a unique aroma and is good in soups.

And also, these mushrooms lend themselves perfectly to pickling.

Mushrooms can be eaten fresh by lightly frying them in oil with potatoes.

White oak mushrooms have long been famous for their special healing properties. Thanks to this mushroom, you can make various decoctions and infusions that treat diseases respiratory tract. IN Ancient Rus' This mushroom was used to treat ulcers and resulting tuberculosis.

The composition of the mushroom is rich in antioxidant vitamins. Also, the composition contains a substance such as carotene, which has a beneficial effect on the functioning of the heart and blood vessels.

Also, there is an opinion that boletus mushrooms have an antiseptic and anti-carcinogenic effect.

Some people consume them raw, using them in salads, however, we will not advise doing this, as it is quite risky.

Similarities with other mushrooms

The reticulated boletus (Porcini oak mushroom) has a very similar appearance to other types of mushrooms. It is easy to confuse it with other names. This does not threaten anything, since such appearance have many useful and non-poisonous counterparts. However, if processed and cooked incorrectly, mushrooms similar to boletus will give a completely different taste.

1. Most often, reticulated boletus mushrooms are confused with porcini mushrooms. However, attentive mushroom pickers know where the differences are. The leg of the porcini mushroom has a kind of mesh that covers the upper part. But the boletus has no such thing.
2. Also, the so-called “gall mushroom” often grows in deciduous forests. It looks very much like a boletus from above, however, there is one significant difference. The gall fungus has a black mesh, as well as pinkish tubes, which the boletus mushroom cannot boast of. Bile mushrooms also choose coniferous forests for distribution.

Borovik Fichtner is another representative of the family. Just like his predecessor chooses broadleaf forests, appreciates calcareous soils, which are rich in vitamins and minerals. Most often found in the Far East and the Caucasus. A significant difference is the absence of tubes, as well as thick padded skin under the cap. It does not bear fruit as much as the reticulated boletus, only from the end of June to the beginning of September. The diameter of the cap of such a mushroom varies from 5 to 15 cm. Its shape has the appearance of a hemisphere. However, the older the mushroom, the flatter the cap becomes.

As for the color, it has a silver-white color. It is easy to confuse them with the reticulated boletus also because they have the same cap diameter and approximately the same length of the stem. However, Fichtner's boletus has a slightly narrower stem diameter, a maximum of only 5 cm. As a result, it looks more elegant. The lower part of the leg also thickens slightly towards the mycelium.

Like the reticulated boletus, Fichtner's boletus belongs to edible mushrooms. It can be consumed in various forms, from fresh to canned. The taste is very similar to mesh, however, there is a slight bitterness.

Another contender, similar both in appearance and in taste, is the porosporous boletus. Like the white one, it has a convex cap, the diameter of which does not exceed 8 centimeters.

The appearance of such a cap is uniform until the first bright rays of sunlight appear, after which it quickly bursts. A whitish pattern appears on the surface, like a mesh.

The color of the mushroom cap has a dark brown or grayish brown undertone.

The leg also has a light brown color.

The lower part itself is dark, while the upper part is boiling white.

Such mushrooms grow in deciduous and coniferous forests. They can be found in areas where moss or low grass is concentrated.

Fruits from early summer to mid-September. Refers to edible mushrooms.

Harm and contraindications

Of course, this flu may not always be harmless and beneficial.

The porcini mushroom (lat. Boletus edulis) represents the most respected mushroom genus - boletus. If earlier he was called the “king of mushrooms,” today we can say about him that he is the undisputed leader of the mushroom rating. This hero has unparalleled taste. It is difficult to confuse the porcini mushroom with its doubles and inedible analogues - it is so beautiful and unique. Boletus is the most desired trophy of a mushroom picker.

What is another name?

It is called white for the ability of the pulp to retain color - boiled, fried or dried, it always remains light. This distinctive feature of boletus was reflected in the popular name. His also name is:

• wood grouse;
• cowshed;
• bear bear;
• barn;
• belevik;
• feather grass;
• yellow and other names.

Features of porcini mushroom

Any type of boletus has a special mushroom aroma and spicy taste. They all have similar shapes, the differences are only in small details. Description of the external data of the most common variety of boletus - spruce (Boletus edulis):

• hat. Color – brownish-brown. Diameter up to 30 cm. In some latitudes they can grow up to 50 cm. The upper skin is tightly adherent to the pulp. In drought it cracks, in rain it becomes covered with mucus.
• Leg. Thick, massive, up to 20 cm high. Thick – up to 5 cm. Shape – cylindrical or club-shaped. Expands towards the base. Color – white, light brown. There is a mesh pattern on the leg. Deeply buried in the soil. There are no traces of a blanket on the leg - boletus mushrooms do not have a “skirt”, the leg is perfectly clean.
• Pulp. In mature individuals it differs in density. Very juicy, white, fleshy, arouses appetite just by its appearance. When overripe, it has a fibrous structure and the color becomes yellowish or beige.
• Tubular body. First white, then yellowish. Older specimens have a greenish appearance.
• Controversy. Olive-brown powder. Size – 15.5 x 5.5 microns.

To determine the age of the mushroom, examine the cap - in young people it is convex, in old people it is flat. With age, its color darkens. Old mushrooms are not suitable for food.

The taste of boletus mushrooms is characterized by the softness of the pulp and the tenderness of the aroma. Heat treatment and drying only enhance the taste.

When and where does it grow?

The distribution range of boletus mushrooms is amazing - they are found on almost all continents. The exceptions are Antarctica and Australia. Japan, Mexico, Mongolia, North Africa, the Caucasus - boletus grows everywhere. You won't find it except in Iceland. In Russia it grows almost everywhere - from the southern latitudes to Kamchatka. The spruce boletus is found in spruce and fir forests.

Each area has its own fruiting time. In warm zones, the mushroom begins to grow in May-June, and bears fruit until October-November. In the north, the growth period is from June to September. It has a long growth phase - it needs to grow for a whole week to reach maturity. Grows in families, rings. Having discovered one specimen, you need to carefully explore the nearby space - there will probably be several more there.

Mushroom pickers tell how to find boletus mushrooms in forest-steppe conditions. They will reveal to you the secrets of mass collection, and where porcini mushrooms are hidden:

Varieties

Boletus mushrooms grow everywhere in the forests of Russia, and there are a great variety of them. It is clear that they are all from the same family. They are distinguished only by the nuances of their appearance. Everyone belongs to the first taste category, everyone has inedible double. Therefore, starting " quiet hunt", carefully study the external signs of those mushrooms that are found in your area.

• The thickness of the tubular body is 2 cm. The shade is yellowish.

It has an early form, characterized by a lighter cap and flesh. Growth begins at the end of spring and continues until October. It settles under pine trees - hence the name. With them it forms mycorrhiza - a fungal root. Found on sandstones, alone and in families. Distribution area: Europe, America, European part Russia.

Birch

• The pulp is white. With a pleasant aroma and taste. In the rift the color changes.
• It is distinguished by a massive leg - it is pinkish-brown. Covered with brown mesh.
• Tubular layer 2 cm thick. Yellow, when pressed, it turns green.

Fans of edible delicacies value hornbeam boletus more than the “classic” porcini mushroom (spruce).

Grows in deciduous forests in warm climatic zones. Distribution: Europe, North America.

Other varieties

There are also the following varieties of porcini mushroom:

• Reticulate. It has a brownish or light ocher cap. The leg is short, cylindrical in shape. Can be confused with moss fly. Prefers beeches and hornbeams. Grows in Europe North Africa and North America. It has a pronounced mesh on the leg. Fruiting time is June-September. Rarely seen.

Semi-white type of porcini mushroom

Who can be confused with?

Boletus mushroom is usually confused with gall mushroom (false boletus mushroom). Signs by which they can be recognized:

• According to the color of the cut. In the gall fungus, the flesh becomes dark, acquiring a pinkish-brown color. The porcini mushroom has white flesh and does not change color.
• The stem of the gall mushroom has a bright pinkish mesh; in a real boletus it is white or yellow.
• The gall mushroom is bitter. The bitterness does not disappear even after cooking. But during pickling, if you add vinegar, it decreases.

Gall mushroom (gorchak) - poisonous false white mushroom

The porcini mushroom has another double - . But with it, confusion occurs less often. Experienced mushroom pickers immediately see the difference, and it is significant:

1. The color of the cap of the double is whitish to olive-gray.
2. The flesh at the break immediately becomes reddish or bluish.
3. The leg is covered with a mesh pattern. Its color is the main sign of a satanic mushroom. It is red-yellow on top, red-orange in the middle, and yellow-brown below. It's hard not to notice the difference!

The value and benefits of the mushroom

Boletus is the most valuable food product. The calorie content of raw boletus is 22 kcal per 100 g. Ingredients:

• proteins – 3.1 g;
• carbohydrates – 3.3 g;
• fats – 0.3 g;
• dietary fiber – 1 g;
• water – 92.45 g;
• ash – 0.85 g.

Boletus mushrooms are simply a storehouse of all possible vitamins, minerals and other useful substances. This is a most valuable product that combines taste and beneficial features. Porcini mushrooms contain everything the body needs, including:

• Selenium. There is so much of it in the pulp that consumption of mushrooms can resist cancer by early stages.
• Ascorbic acid– normalizes the functioning of all organs.
• Calcium, iron, phosphorus and other vital elements.
• Phytohormones– eliminate inflammation.
• B vitamins– strengthen nervous system, help normalize energy metabolism, improve memory and sleep, prevent infection, improve mood and appetite.
• Riboflavin– normalizes the functioning of the thyroid gland, promotes hair and nail growth.
• Lecithin– useful for patients with atherosclerosis and anemia. Clears blood vessels of cholesterol.
• B-glucan– an antioxidant that protects the immune system, saves the body from fungi, viruses, and bacteria.
• Ergothioneine– renews cells, restores liver and kidneys, benefits bone marrow, improves vision.

Harm

• children;
• pregnant women;
• people with kidney disease and gastrointestinal diseases.

Porcini mushrooms are able to absorb harmful substances from environment. Do not collect them near businesses and industrial areas.

Boletus spores, like other mushrooms, can cause negative reactions in allergy sufferers. The main danger is eating its double - the gall fungus. Therefore, you need to carefully study the signs of this inedible.

Use in food

Porcini mushroom is a low-calorie food product. Suitable for cooking, frying, drying, stewing, pickling. The cooked pulp is tender and has a mushroom smell.

Eating porcini mushrooms in dried form allows the body to absorb up to 80% of proteins. Nutritionists advise eating dried boletus mushrooms.

Most strong aroma For dried porcini mushrooms, dried using the correct technology, it is important that the pulp loses moisture gradually. Mushrooms are considered a difficult food to digest. But it is dried boletus mushrooms that are the most easily digestible mushroom product.

Growing

White mushroom, despite its unsurpassed taste, is not grown in industrial scale– unprofitable. Usually, amateur gardeners are engaged in cultivation. On personal plot must be coniferous or deciduous trees. There should be no fruit trees, cultivated shrubs or vegetables nearby. The most difficult thing is to create conditions for the successful creation of connections between tree roots and mycelium.

It is desirable that the site is adjacent to the forest. If this is not possible, you need to have at least a few pine, aspen, birch, oak or spruce trees on your future “plantation.” Trees on the site must be at least 8 years old. There are two ways to grow porcini mushrooms – from mycelium and from caps.

Growing from mycelium

Cultivation begins with the purchase of planting material. You need to buy mycelium in specialized stores. Next, prepare the area and plant the mycelium:

1. The soil is exposed near the trunks. The top layer is removed - approximately 20 cm. The diameter of the circle should be approximately 1-1.5 m. The removed soil is saved - it will be needed to cover the crops.
2. A layer of peat is applied to the area prepared for planting. Rotted compost can be used. The fertile layer should not be thicker than 2-3 cm.
3. Mycelium is placed on top. The interval between adjacent pieces is approximately 30 cm. The pieces are laid out in a checkerboard pattern.
4. The mycelium is covered with previously removed soil. Water generously. You need to pour about 3 buckets of water under one tree. Pour carefully so that the soil does not erode.
5. Next, mulch the watered soil with straw. The layer thickness is 30 cm. This is done to maintain the required humidity - so that the mycelium does not dry out. Crops need to be watered weekly. Be sure to add nutritious fertilizer to the water.

Before frost, areas with mushrooms are covered. For insulation you can use moss, spruce spruce branches, fallen leaves. With the arrival of spring, the insulation is raked using a rake.

A year will pass and the first fungi will be removed. If you properly care for the mycelium, water and feed it on time, the mushroom “plantation” will bear fruit for up to 5 years.

Growing from caps

To implement this method, you will need to get a few mushroom caps. Find mature, or better yet, overripe boletus mushrooms in the forest. The diameter of the cap should be at least 10 cm. It is best that when broken, the cap has a greenish tint - this indicates the maturity of the spores.

When collecting caps, you need to remember what trees the mushrooms grew under. It will be necessary to sow spores under the same trees. If a boletus is found under a spruce, it is unlikely that it will take root under a birch or aspen.

The procedure for preparing the site and planting seed:

1. About a dozen caps are soaked in a bucket of water. It is advisable that the water be rainwater. Add one thing per 10 liters:
   • alcohol – 3-5 tbsp. l.;
   • or sugar – 15-20 g.

   Mushrooms should be soaked no later than 10 hours after collection - otherwise they will spoil.

2. After 24 hours, you should mash the boletus caps. Knead until you get a mass similar to jelly. After straining it through cheesecloth, the water is separated from the mushroom tissue with spores.
3. Prepare a place for planting - exactly as in the previous version. But be sure to water peat or compost with tannins for disinfection. To prepare the solution take:
   • black tea – 100 g;
   • or oak bark - 30 g.

   Tea is brewed in 1 liter of boiling water. The second option is to boil oak bark for 1 hour. Water the soil with the cooled solution - 3 liters for each tree.

4. Next, they begin landing - on the prepared fertile layer pour water containing boletus spores. The solution is stirred while pouring. The crushed caps are placed on top, the planting is covered with previously removed soil, and covered with straw.

Boletus mushrooms can reach a yield of up to 250 kg per 1 hectare. Under each tree, during the season, you can collect a bucket of porcini mushrooms.

All that remains is to take care of the crops - water them regularly, sparing no water. If the soil dries out, the mycelium will die before it has time to germinate. For the winter, the area is insulated with spruce branches or leaves. In the spring, they rake it. The first mushrooms will appear next summer or autumn.
