What Are Truffle Mushrooms? And Where Do Truffles Come From?

Truffles belong to the fungi family, Ascomycota, and are spore-producing organs.

In terms of function, truffles are much like mushrooms and are edible. The difference is that truffles grow under the soil.

The primary function of truffles is to grow spores to give rise to new offspring. Truffles have a unique look, but they are only one of the varieties of mushrooms. They are round and have a fruiting body with spores.

If you are still confused with the name related to chocolate, all you need to know is that truffles are one of the different types of mushrooms. In the past, this mushroom was used as a medicine. But as time went on, food experts' culinary skills have made truffles an essential part of pasta.

Truffles have a pungent smell yet a rich aroma. In addition to the strong, pungent smell, truffles are known for their nutrients and many health benefits.

They are either white or black and are easily found in the dense forest regions of the Northern Hemisphere, France, Italy, and the Balkans. The body is yellowish, tan, or dark brown, and has shallow to deep lines.

What exactly are truffles and where do they hail from?

When we say truffle, it might remind you of chocolate treats, but you will be amazed to know it is a fungus and mushroom. Truffles are tubers, and they are either white or black, depending on the season.

White truffles are harvested from the end of September to early January. Black truffles vary depending on season and their specific variety.

The truffles naturally grow from the fruiting bodies of fungi that grow on the host trees' roots; this is known as a symbiotic relationship. Truffles tuber or fungus explores minerals, nutrients, and water that it passes to the tree.

The host tree, in exchange, provides sugar to the fungus, which it produces through the process of photosynthesis. Truffle fungus and the tree depend on each other for their food source.

Many species of tree can serve as a host for the fungus and vice versa. Truffles usually grow in the calcareous soil attached near the roots of the broadleaved trees like hazelnut and oak.

You might have come across the white truffles in an exotic delicacy, but did you know they are one of the costliest food items on the planet?

Truffles are found in the wild; they grow underground and spread the tubers outward. Truffles have a unique scent that attracts fungivores to them.

They are found in both the north and south of continents. In the Northern Hemisphere, animals like small mammals, rabbits, pigs, squirrels, and mice eat truffles. In the Southern Hemisphere, truffles are eaten by armadillos, kangaroos, meerkats, and rats.

Large mammals like deer, bears, baboons, pigs, and wallabies also eat truffles. When consumed, some flesh is digested while some are released from the body undamaged.

These spores then return to the soil through animal feces. The spores present in the feces are deposited in the nearby area and try to find their way to the roots of the host trees present in the ecosystem.

Truffles do not grow in poop, but they find their way from the spores present in the animal poop to the roots of its host tree.

Unlike most other plants that convert sunlight into energy by photosynthesis, truffles depend on the host trees for their nutrients. This symbiotic relationship between the roots of the tree and the fungi is known as mycorrhizae.

Also, truffles are healthy. They are rich in carbs, protein, fiber, vitamin C, sodium, calcium, phosphorus, magnesium, manganese, and iron. 

Where in Italy do truffles come from?

Truffles belong to the fungi kingdom, a mushroom with fruiting bodies (a spore-producing organ). Truffles grow underground; they do not have a stem or extra spore-bearing surface. The spore itself is the root and fruit.

In Italy, you can find truffles in different areas like Irpinia, Le Marche, and Lazio. The leading variety producer of quality truffles is the Piedmont region due to the soil, which has ideal conditions (rich in calcium, humid and soft). These truffles are also known as French black truffles.

The best region to harvest the high-quality white truffle is Alba, Monferrato, Langhe, and Roero.

Perugia is one of the most beautiful Italian provinces where truffle hunters wander in the frosty mountains in search of truffles. Their trained dogs sniff out this spore-bearing, fruit mushroom when they are ripe, a tradition that has been done for centuries.

But did you know, the word truffle in Italy is known as ‘Tartufo.’ It is taken from the Latin word, which means tuber or a lump. Truffles grow best in humid and colder regions; the truffles are also located in the cold mountain forest regions of Umbria, central parts of Tuscany, and Le Marche.

They are found growing below the host tree roots of hazelnut, oak, poplar, and willow trees.

There are in total, nine varieties of truffles that we can eat. But the main varieties only grow during the winter season and are usually named based on the color of the fruit, like white or black.

The best region to find white truffles in abundance is Langhe province. It is located near the city of Alba in Piedmont. They can also be found in Le Marche, Umbria, and Tuscany. Due to the favorable unique microclimate and required soil conditions, the area is full of truffle as you find here poplars, oak, and willow trees.

The black truffle color varies from dark brown to black, and an outer cover with a reddish shade. The inside part is dark with white stripes. The best regions to locate these truffles are Umbria and Norcia, where farmers grow truffles.

This particular truffle was one of the most expensive truffles sold in the world. The person who brought the high-end truffles was a bidder from China.

What a crazy price for a mushroom, right? The reason is these truffles are so scarce. They are found hidden in the cold high mountain regions under the ground of the host trees. It is tough to find them, and trained dogs have to sniff out the ripe truffles.

As for white truffles (Tuber magnatum), they are considered the rarest species; they are grown only in a few areas in Italy, Croatia, and Slovenia. This rare species grows from October to December.
