Boletus edulis is not endangered, but it's hard to domesticate
Boletus edulis, commonly known as the king mushroom, is a highly prized edible mushroom. It is considered a delicacy in many cuisines around the world and is used in a variety of dishes, from soups and pasta to risottos and omelettes. The mushroom is widely distributed in the Northern Hemisphere across Eurasia and North America and has also been introduced to southern Africa, Australia, New Zealand, and Brazil.
While Boletus edulis is not considered endangered, it is challenging to domesticate due to its symbiotic relationship with living trees. This mushroom forms a mutualistic association with tree roots, particularly in deciduous and coniferous forests and tree plantations. Through this symbiosis, the fungus obtains vital minerals from the soil, while the tree benefits from the energy nutrients provided by the fungus, aiding in photosynthesis.
The inability to easily domesticate Boletus edulis means that it is primarily found in its natural habitats. In Europe, Boletus edulis is commonly found in Italy, France, Scotland, Russia, and Sweden. It is also prevalent in North America, particularly in the northeastern region, where it is known as the King Bolete or the California king bolete (Boletus edulis var. grandedulis). However, there is an ongoing debate about whether the American variety is the same species as its European counterpart.
The difficulty in domesticating Boletus edulis also contributes to its value and prestige in culinary circles. It is a sought-after ingredient in gourmet meals and is often used in world-class five-star restaurants. The mushroom is known for its pleasant flavours, rich aroma, creamy texture, and high nutritional value. It is a good source of proteins, amino acids, vitamins, minerals, and dietary fibre, while being low in fat and digestible carbohydrates.
Additionally, Boletus edulis is considered a safe mushroom to forage for culinary purposes. While it has some look-alikes, careful examination can easily distinguish it from potentially poisonous mushrooms. Its unique characteristics, such as the whitish or yellowish pores and the netted pattern on the stem, make it relatively easy to identify.

It's a safe mushroom to pick due to its distinctiveness
Boletus edulis, commonly referred to as the king mushroom, is one of the most esteemed edible fungi in the world. It is a staple ingredient in Italian, Swedish, Polish, German, French, and Spanish cuisines. It is also frequently used in gourmet meals in world-class five-star restaurants. The king mushroom is very difficult to domesticate and is commonly found in natural habitats in some parts of Europe, including Italy, France, Scotland, Russia, and Spain. It is also found in Asia, South Africa, North America, and Australia.
The Boletus edulis mushroom is considered one of the safest wild mushrooms to pick due to its distinctiveness. It has a large brown cap that can reach up to 30 cm in diameter and 3 kg in weight. The cap has a greasy surface texture that looks like a penny bun. The pore surface of the fruit body is whitish when young, but ages to a greenish-yellow. The stout stipe, or stem, is white or yellowish in colour, up to 20 cm tall and 10 cm thick, and partially covered with a raised network pattern, or reticulations. The mushroom stem is yellow or white in colour and has a dimension of up to 10 cm in diameter and between 5 to 25 cm in height. The meat of the king mushroom is white, sweet, earthy, and smells fantastic.
The Boletus edulis mushroom can be easily distinguished from other similar mushrooms by careful examination. The most similar poisonous mushroom may be the devil's bolete (Rubroboletus satanas), which has a similar shape but has a red stem and stains blue on bruising. It is often confused with the very bitter and unpalatable Tylopilus felleus, but can be distinguished by the reticulation on the stalk. The porcini have a whitish, net-like pattern on a brownish stalk, while the Tylopilus felleus has a dark pattern on white. The porcini have whitish pores, while the Tylopilus felleus has pink pores. If in doubt, tasting a tiny bit of flesh will yield a bitter taste. It can also resemble the "bolete-like" Gyroporus castaneus, which is generally smaller and has a browner stem.
The Boletus edulis mushroom is considered a good source of proteins and amino acids, with a protein content comparable to beef. It is also rich in carbohydrates, vitamins, minerals, and dietary fibre, while low in fat and calories. It has a unique sweet and meaty taste and a pleasant aroma, making it a popular ingredient in various dishes such as risotto, omelettes, sauces, and meat dishes.

It is commonly known as the penny bun or porcino (Italian) and is widely distributed in the Northern Hemisphere across Eurasia and North America. It is considered one of the safest wild mushrooms to pick for the table, as few poisonous species closely resemble it.
The fruit body of the B. edulis has a large brown cap that can reach 30 cm (12 in) and, rarely, up to 40 cm (16 in) in diameter and 3 kg (6 lb 10 oz) in weight. The pore surface is whitish when young but ages to a greenish-yellow. The stipe, or stem, is white or yellowish, up to 20 cm (8 in) tall and 10 cm (4 in) thick. The fungus grows in deciduous and coniferous forests and tree plantations, forming symbiotic relationships with living trees.
B. edulis is considered a good source of proteins and amino acids, with a protein content comparable to beef. It is also rich in carbohydrates, vitamins, minerals, and taste compounds, while low in fat and calories. It has been shown to possess antioxidant, antineoplastic, anti-inflammatory, antibacterial, hepato-protective, and antiviral activities. The mushroom's antioxidant properties are attributed to its high content of polyphenols, flavonoids, L-ascorbic acid, β-carotene, and tocopherols.
In addition to its nutritional and medicinal value, B. edulis is also known for its exceptional flavour, making it a highly appreciated mushroom species. It is commonly prepared and eaten in soups, pasta, or risotto.

It's a staple ingredient in Italian, Swedish, Polish, German, and French cuisines
Boletus edulis, commonly referred to as the king mushroom, is a highly prized edible mushroom. It is considered a safe mushroom to forage for and eat, as none of its close lookalikes are poisonous. It is also a good source of protein and amino acids. This mushroom is widely distributed in the Northern Hemisphere, particularly in Europe, Asia, South Africa, North America, and parts of Australia and New Zealand.
In Europe, Boletus edulis is a staple ingredient in Italian, Swedish, Polish, German, and French cuisines. It is also known as Porcini, Cep, or boletus bulbosus in Italy, where it is commonly used in gourmet meals in world-class five-star restaurants and people's homes. The Italians also call it fungo porcino, which means hog mushrooms, due to the young fruit bodies' resemblance to piglets or because pigs enjoy eating them. The French call it Bouchon or cepes, and it is considered a fungus of choice because of its unique sweet and meaty taste and pleasant aroma.
In Sweden, the mushroom is called "Karl Johan svamp" after a Swedish-Norwegian king who enjoyed eating them. Boletus edulis is also commonly used in Polish cuisine, where it is called "prawdziwek" or "borowik". In Germany, it is known as Steinpilz, or stone mushroom, referring to the species' firm flesh. While specific names for the mushroom in German-speaking countries were not found, it is reasonable to assume that it is also commonly used in their cuisine, given its popularity in neighbouring countries.

penny-bun,-or-king-bolete'>It's also known as Porcini, , Penny Bun, or King Bolete
Boletus edulis is a type of mushroom that is commonly known as the penny bun, porcini, or king bolete. It is a basidiomycete fungus and the type species of the genus Boletus. It is considered a delicacy in many cuisines and is commonly prepared and eaten in soups, pasta, or risotto. B. edulis is widely distributed in the Northern Hemisphere across Eurasia and North America but does not occur naturally in the Southern Hemisphere. It is prized as an edible mushroom with abundant flavour compounds and is considered one of the safest wild mushrooms to pick for consumption. It has a large brown cap, a stout white or yellowish stem, and a whitish pore surface that ages to a greenish-yellow.
The common names for B. edulis vary by region. The standard Italian name, porcino (plural porcini), means porcine and is derived from the term "hog mushrooms", used by the Ancient Romans due to the resemblance of young fruit bodies to piglets or their fondness for eating them. The English name penny bun refers to its rounded brownish shape, while the German name Steinpilz, or stone mushroom, refers to the species' firm flesh. The western North American species, commonly known as the California king bolete (Boletus edulis var. grandedulis), is a large, darker-coloured variant first identified in 2007.
B. edulis is a good source of protein and amino acids, with a protein content comparable to beef. It is also rich in dietary fibre and low in fat and digestible carbohydrates. It contains vitamins B1, B2, B3, B5, B6, B9, C, and E, as well as antioxidants like beta carotene, lycopene, and other flavonoids. Additionally, it is a source of minerals like iron, calcium, magnesium, copper, phosphorus, potassium, zinc, and selenium.
While B. edulis is considered one of the safest wild mushrooms to consume, it is important to distinguish it from similar-looking poisonous mushrooms. The most similar poisonous mushroom is the devil's bolete (Rubroboletus satanas), which has a red stem and stains blue when bruised. B. edulis can also be confused with Tylopilus felleus, but can be distinguished by the whitish, net-like pattern on its brownish stalk.
B. edulis is difficult to cultivate and is typically available fresh in autumn throughout Europe and Russia. It is often dried, packaged, and distributed worldwide, as it retains its flavour after drying. It can also be pickled or cooked in various ways, such as sautéing in olive oil or butter, crumb-frying, or adding to salads.
