Some fungi are called truffles.
They grow in the dirt. People think they are very special. Some grow near tree roots. They can taste very good. We can find them in many places. Have you ever seen one?

They grow in the dirt. Many people think they are special. They can taste very good.
Some truffles grow near tree roots. New kinds are found in new places. One kind was found in mountains. Two more kinds were found in Brazil. These grow near pecan roots. It is fun to find new kinds of truffles.
Tuber is a group of fungi.
These fungi include many types of truffles. People think truffles are very special. They are used as delicious food. Scientists think these fungi are very old. They may have started at the end of the Jurassic period. That was 156 million years ago.
People still find new kinds of truffles. In 2015, experts found a new kind. They found it in the Dinaric Alps. This is in Southeastern Europe. In 2016, they found two more kinds in Brazil. One kind is called Tuber floridanum. Another kind is called Tuber brennemanii. These two grow near pecan rootlets. Rootlets are very small parts of a tree root. These truffles grow in a special way with the trees. It is exciting to find these new species. A species is a specific kind of living thing.

Tuber is a group of fungi.
These fungi belong to the family Tuberaceae. This group includes many types of truffles. People think truffles are very special. They are used as delicious food. These fungi are quite old. Scientists use molecular dating to study them. This helps them find the age of life.
How do these fungi work in nature? Some species grow in a special way. They grow in association with tree roots. For example, two kinds grow near pecan rootlets. Rootlets are very small parts of a root. This link helps the fungus live. The fungus and the tree grow together. This way of living is very important.
These fungi have a very long history. Scientists believe they are ancient. They may date back to the Jurassic period. This was a time long ago. It happened about 156 million years ago. That is a huge amount of time. The world has changed since then.
People still find new species today. In 2015, experts found a new kind. This species is named Tuber petrophilum. It is a relative of other truffles. They found it in the Dinaric Alps. This place is in Southeastern Europe. In 2016, two more kinds were found. They were found in Brazil. One is called Tuber floridanum. The other is Tuber brennemanii.
Finding new truffles is very exciting. Tuber floridanum has a special name. Its commercial name is Trufa Sapucaya. This name means "The last Guarany breath." It shows how people name things. Every new discovery tells us more. We learn about life on Earth. It is a wonderful way to study nature.
The genus *Tuber* represents a specific group of fungi within the Tuberaceae family.
These organisms include many different species of truffles. Many people consider these fungi to be highly valued delicacies. This means they are prized for their unique qualities in food. Understanding *Tuber* helps scientists learn about fungal diversity. It also shows how ancient life forms continue to exist today.
Many species in this genus grow through a specific biological process. They live in association with the roots of trees. For example, some species grow near pecan rootlets. Rootlets are the very small parts of a plant's root system. This connection allows the fungus to live and grow. The fungus and the tree roots exist together in a shared environment. This relationship is a key part of how these fungi survive.
Scientists classify these fungi into different species based on their traits. Some species are very closely related to one another. For instance, *Tuber petrophilum* is a close relative of *Tuber melanosporum*. It is also related to *Tuber brumale*. Each species may grow in different locations or with different plants. These distinctions help researchers map out the entire *Tuber* family tree.
Research into the history of *Tuber* uses a method called molecular dating. This technique allows scientists to estimate when a group first appeared. Based on this dating, the genus may go back to the end of the Jurassic period. This period occurred approximately 156 million years ago (Mya). This makes the *Tuber* genus an incredibly ancient lineage of life. They have survived through many massive changes on Earth.
New discoveries regarding these fungi continue to happen in the modern era. In 2015, experts identified a new species called *Tuber petrophilum*. They found this fungus in the Dinaric Alps. This mountain range is located in Southeastern Europe, specifically in Serbia. This discovery added a new branch to our knowledge of the genus. It proved that even well-studied groups still hold secrets.
More new species were discovered shortly after in 2016. These two new species were found in the country of Brazil. One of these is named *Tuber floridanum*. It is also known by the commercial name Trufa Sapucaya. This name carries a poetic meaning: "The last Guarany breath." The second species found in Brazil is named *Tuber brennemanii*. Both of these grow in association with pecan rootlets.
The study of *Tuber* connects to many different scientific fields. It touches on biology through the study of fungal life. It also connects to botany because of the way they interact with tree roots. Even history is involved when we look at the Jurassic period. Every new species found in places like Brazil or Serbia helps us understand the world. These discoveries show how life is distributed across the entire planet.
