Mushrooms, part of the Fungi kingdom, are among the most abundant organisms on the planet. They are mysterious, with only two percent of species identified. Their delicate nature makes fossils extremely rare and difficult to discern from other microorganisms. The oldest confirmed mushroom fossil was 460 million years old, until a new discovery of fossilized mycelium in the Democratic Republic of Congo pushed back the origins of mushrooms to between 715 and 810 million years ago. This discovery may reshape our understanding of the evolution of organisms on Earth.

The first mushrooms may have appeared between 715 and 810 million years ago
The evolution of the kingdom Fungi, commonly known as mushrooms, is still largely a mystery. Only two percent of species have been identified, and their delicate nature means fossils are extremely rare and difficult to discern from other microorganisms.
However, a 2020 study led by Steeve Bonneville from the Université libre de Bruxelles found that the first mushrooms may have appeared between 715 and 810 million years ago, 300 million years earlier than previously believed. The fossilized remains of mycelium, a network of interconnected microscopic strands, were discovered in rocks in the Democratic Republic of Congo. These rocks were formed in a lagoon or coastal lake environment and are estimated to be between 715 and 810 million years old.
The discovery of these ancient mushrooms has significant implications for our understanding of early life on Earth. Bonneville suggests that "fungi were already there" when plants first evolved, and may have played an important role in the colonization of the continental surface by the first plants.
The study used multiple molecular analysis techniques, including synchrotron radiation spectroscopy and fluorescence microscopy, to detect traces of chitin, a compound found in the cell walls of fungi. These techniques provided clear evidence of chitin in the fossil's filamentous networks, supporting the identification of the remains as ancient fungi.
While this discovery provides valuable insights into the evolution of mushrooms and their role in Earth's history, further research is needed to fully understand the implications and continue to fill in the gaps in our knowledge of these ancient organisms.

The oldest mushroom fossil is 460 million years old
The oldest mushroom fossil ever discovered is 460 million years old. However, recent studies have found evidence of mushrooms that are much older.
A group of researchers led by Professor Steeve Bonneville from the Université libre de Bruxelles discovered a new mushroom fossil that is 460 million years old. The fossil was identified using molecular composition analysis techniques, including synchrotron radiation spectroscopy, confocal microscopy, fluorescence microscopy, and electron microscopy. These techniques allowed the researchers to study the chemistry of the organic remains without damaging them, which is a common issue with traditional methods that use corrosive acid compounds. The fossilized remains of mycelium, a network of interconnected microscopic strands, were discovered in rocks from the Democratic Republic of Congo.
Additionally, Bonneville and his team also found fossilized fungal filaments in a Neoproterozoic shale rock from the same region. The filaments were identified as fungi due to the presence of chitin, a compound found in the cell walls of fungi. This discovery provides evidence that fungi were present on land over 500 million years ago, and possibly even earlier during the Ediacaran period 635 million years ago.
While the 460-million-year-old mushroom fossil is the oldest confirmed specimen, there is evidence suggesting that mushrooms may have appeared even earlier in Earth's history. A study published in 2020 reported the discovery of fossilized mycelium in rocks dating back between 715 and 810 million years. These ancient rocks, found in the Democratic Republic of Congo, indicate that mushrooms may have played a crucial role in the colonization of the Earth's surface by plants around 500 million years ago.
Furthermore, a 2019 study by Corentin Loron and colleagues from the University of Liege, Belgium, described the discovery of microfossils in Canada that were estimated to be between 900 million and one billion years old. The presence of chitin in these fossils provided strong evidence that they belonged to fungal species. This finding significantly pushes back the estimated arrival of fungi on Earth to the earliest stages of life on land.

Fossils in Canada suggest fungi date back 900 million to 1 billion years
Fungi are believed to have diverged from other life forms around 1 billion years ago, with recent fossil discoveries in Canada suggesting that they date back 900 million to 1 billion years. This discovery reshapes our understanding of the world, as it indicates that the distant past may have been more "modern" than previously thought.
Fungi play a crucial role in the world, performing unseen tasks such as breaking down detritus and dead matter, and cycling nutrients throughout the environment. They also enable plant life by forming vast webs in the soil, transferring chemical signals, food, and water. Despite their importance, much of the early history of fungi remains a mystery. There is a significant gap in the fossil record, with fungi seemingly vanishing for hundreds of millions of years.
The recent discovery of fossilized fungal filaments in the Democratic Republic of Congo and Canada has shed some light on the early history of fungi. These fossils were identified using advanced molecular analysis techniques, including synchrotron radiation spectroscopy and fluorescence microscopy, which allowed researchers to study the chemistry of organic remains without damaging them. The presence of chitin, a compound found in fungal cell walls, was detected in the fossils, confirming their identity as fungi.
These fossils date back to a time when life on Earth's surface was in its infancy. The discovery suggests that fungi may have played a crucial role in the colonization of the land by plants. According to Steeve Bonneville, a researcher at the Université libre de Bruxelles, Belgium, "The presence of fungi in this transitional area between water and land leads us to believe that these microscopic mushrooms were important partners of the first plants that colonized the Earth's surface around 500 million years ago."

Ancient mushrooms may have been partners of the first plants on Earth
Fungi, or mushrooms, are some of the oldest organisms on Earth. They diverged from other lifeforms around 1 billion years ago and are more closely related to animals than plants. The earliest known fungi were thought to have appeared around half a billion years ago, but recent discoveries have pushed back the timeline of their arrival to the earliest reaches of life on land.
One such discovery was made by Corentin Loron, a PhD student from the University of Liege, Belgium, and their colleagues. They examined microfossils unearthed in Canada and found the presence of chitin, a fibrous substance found in fungal cell walls. The microfossils were determined to be between 900 million and 1 billion years old.
Another significant finding was made by a group of researchers led by Steeve Bonneville from the Université libre de Bruxelles. They discovered fossilized remains of mycelium, a network of interconnected microscopic strands, in rocks from the Democratic Republic of Congo. These rocks were dated to be between 715 and 810 million years old, a time when life on Earth's surface was just beginning. Bonneville suggests that "these microscopic mushrooms were important partners of the first plants that colonized the Earth's surface around 500 million years ago."
The discovery of ancient fungi fossils has shed new light on the evolution of life on our planet. It indicates that fungi may have played a crucial role in the colonization of the continental surface by the first plants. This partnership between fungi and plants may have been instrumental in the development of early terrestrial ecosystems.
While the exact nature of this partnership requires further study, it is clear that fungi are essential for plant life. They break down detritus and dead matter, cycle nutrients, transfer chemical signals, and facilitate processes like fermentation. The discovery of ancient fungi fossils provides valuable insights into the deep history of these organisms and their role in shaping life on Earth.

Fungi branched off from animals over 1 billion years ago
The evolution of fungi, or mushrooms, is a fascinating but mysterious topic. Fungi are more closely related to animals than to plants, as they share a more recent common ancestor. In fact, fungi branched off from animals over 1 billion years ago.
The discovery of fossils is a key method for understanding the evolution of life on Earth. However, the nature of fungal fruiting bodies, which are soft and easily degradable, means that they are rarely preserved as fossils. This is why, until recently, the oldest confirmed mushroom fossil was dated at just 460 million years old.
However, in 2019, scientists reported the discovery of a fossilized fungus, Ourasphaira giraldae, in the Canadian Arctic. This fungus dates back to around 1 billion years ago, a time when life on Earth was very different. The land was relatively bare, likely containing only bacteria, and plants had not yet evolved to live on land.
More recently, a group of researchers led by Steeve Bonneville from the Université libre de Bruxelles discovered an even older mushroom fossil. Using molecular analysis techniques, they identified fossilized mycelium, a network of interconnected microscopic strands, in rocks from the Democratic Republic of Congo. These rocks have been dated to between 715 and 810 million years old, meaning that the fossils are at least 300 million years older than previously discovered mushroom fossils.
The discovery of these ancient fungal fossils is significant because it provides insight into the early evolution of life on Earth. Fungi play an important role in the ecosystem, breaking down dead organic matter and cycling nutrients throughout the environment. They also have important industrial applications, such as in fermentation. By studying their distant past, we can gain a better understanding of the role they have played in shaping life on our planet.
