What types of boletus are there?
Even if you're not a mushroom expert, you've probably heard of boletus mushrooms or eaten them before. But perhaps you didn't know that there are actually several types of boletus mushrooms within this category, and not all of them are safe to eat.
Boletus mushrooms are a genus of edible and inedible mushrooms belonging to the Boletaceae family.
These mushrooms are widely appreciated for their flavor and versatility in cooking, but they are also a very diverse group that includes species with very distinct characteristics and culinary values.
The Boletus genus encompasses a large number of species, many of which are highly sought after by mycologists and food lovers.
But what are their differences and how many different types exist? Keep reading this article to find out!
The genus boletus
Before getting into the nitty-gritty, it's important to understand what a boletus is.
In botanical terms, a boletus is a mushroom belonging to the Boletaceae family.
Unlike other mushrooms, such as those in the Agaricus or Lactarius genera, boletus mushrooms are characterized by having pores instead of lamellae on the underside of the cap.
These pores produce spores, which are dispersed when the mushroom matures. Their structure is generally fleshy and compact, giving them a unique texture that makes them especially attractive for consumption.
Over the years, boletus mushrooms have been widely studied due to their ecological and culinary importance. However, it is essential to recognize that within the Boletus genus, there are species that are edible, others that are not, and some that can even be toxic.
Types of boletus
Once we're settled, let's show you some of the most representative species within the Boletus genus.
1. Boletus edulis (King of Boletus or Pine Boletus)
If you've ever eaten boletus in a restaurant dish or mixed with something else, it's probably been this type.
One of the most well-known and appreciated boletus mushrooms worldwide is Boletus edulis.
This mushroom is famous for its excellent flavor and meaty texture, making it one of the most sought-after ingredients in gastronomy. It is commonly known as the "King of Boletus" or "Pine Boletus" because it grows in coniferous forests and its flavor is considered one of the most exquisite among edible mushrooms.
Boletus edulis has a light to dark brown cap, with a texture that can be rough. Its stem is robust and usually white or slightly yellowish. It is commonly found in forests of pine, fir, and other coniferous trees, and its appearance season is in summer and autumn.
2. Boletus badius (Brown Boletus)
Boletus badius, known as the "Brown Boletus," is another highly prized member of the Boletus genus. This mushroom is distinguished by its dark brown cap, sometimes almost black. Its stem is pale, often white or beige, with a more fibrous texture than Boletus edulis.
Boletus badius generally grows in acidic, moist soils and is most often found in coniferous forests, although it can also appear in mixed forests. It has a delicate flavor that makes it an excellent ingredient for soups, sauces, and stews. It is an edible species, but less well-known than Boletus edulis.
3. Boletus pinophilus (Pine Boletus)
Boletus pinophilus is very similar to Boletus edulis in appearance and flavor. This mushroom is found in pine forests, especially on calcareous soils. Its cap is light brown, and its stem is white or beige. It is an edible species and can be used in the same way as other boletus mushrooms in cooking.
Its flavor is milder than that of Boletus edulis, but it is still highly prized for its meaty texture. It is also considered easy to identify due to its characteristics and its growth habit in pine forests.
4. Boletus aereus (Black Boletus)
Boletus aereus, also known as "Black Boletus," is a species distinguished by its dark brown, almost black cap. This mushroom is less common than other boletus mushrooms, but its flavor is highly prized in gourmet cooking.
It is found in mixed forests, preferably in soils rich in organic matter. It is known for its resistance to decomposition, which allows it to keep longer than other boletus. Its flesh is white, but darkens when cut, making it easily identifiable.
5. Boletus subtomentosus (Rough Boletus)
Boletus subtomentosus, known as the "Rough Boletus," is characterized by its rough, light to dark brown cap. Its stem is robust and pale, while the flesh is white, which can turn yellowish when cut.
It is found mainly in oak forests and other deciduous tree species. Although edible, its flavor is less pronounced than that of other species, making it a more unassuming mushroom in the kitchen. However, it is still a valid choice for those seeking a meaty, smooth texture in their dishes.
Precautions when collecting boletus
You should know that, as with all mushroom harvesting, you should only harvest and consume those you are sure you can identify without a doubt.
It's important to keep in mind that not all boletus mushrooms are edible, and some can be toxic or cause adverse reactions.
Proper identification of each species is essential to avoid health problems.
Some species, such as Boletus satanas, are poisonous and can cause serious poisoning. It may seem obvious in the photograph because it has a seemingly poisonous color, but it's easy to confuse them when they're smaller.
Therefore, you should always seek the guidance of a mycology expert when harvesting mushrooms in the wild.
