What You'll Learn
Mushroom origins in ancient civilizations
Mushrooms have a rich and ancient history, deeply intertwined with human civilization. Archaeological evidence suggests that mushrooms were consumed and revered by various ancient cultures, indicating their presence in the "Old World" long before the discovery of the "New World." For instance, cave paintings in North Africa, dating back to 9000 BCE, depict mushrooms, hinting at their significance in early human societies. These findings confirm that mushrooms were not a New World discovery but rather an integral part of Old World traditions and practices.
In ancient Egypt, mushrooms were considered a food fit for royalty and were often associated with immortality and the divine. Hieroglyphics and tomb paintings from around 2500 BCE show mushrooms being offered to pharaohs and deities. The Egyptians believed that mushrooms held mystical properties, and their consumption was restricted to the elite. This reverence for mushrooms highlights their importance in one of the world's earliest civilizations, firmly placing them in the Old World context.
Moving eastward, ancient Chinese civilizations also recognized the value of mushrooms, both as a culinary delicacy and for their medicinal properties. Texts from the Shang Dynasty (1600–1046 BCE) mention mushrooms as a tribute item, while the *Shen Nong Ben Cao Jing* (Divine Farmer’s Materia Medica), a classic herbal text from around 200 BCE, lists several mushroom species for their therapeutic benefits. The Chinese association of mushrooms with longevity and health further underscores their Old World origins and cultural significance.
In Mesoamerica, while mushrooms like *Psilocybe* were used in spiritual rituals by indigenous cultures, these practices emerged independently and are not evidence of New World origins for mushrooms as a whole. Instead, they demonstrate the universal human fascination with fungi across different civilizations. The global presence of mushrooms in ancient societies, from Europe and Asia to Africa, solidifies their status as an Old World phenomenon, predating the exploration of the Americas.
Lastly, ancient Greek and Roman writings also reference mushrooms, with figures like Pliny the Elder documenting their use in food and medicine. The Greeks associated mushrooms with the gods, while the Romans cultivated them for culinary purposes. These historical accounts, combined with archaeological evidence, provide a comprehensive picture of mushrooms as a deeply rooted element of Old World cultures, long before their presence was noted in the New World.

Historical records of mushroom cultivation
The cultivation of mushrooms has a rich and varied history that spans both the Old World and the New World, though the practices and species cultivated often differed between the two. Historical records suggest that mushroom cultivation began in the Old World, particularly in East Asia, where it has been practiced for over a thousand years. Ancient Chinese texts, such as the *Shen Nong Ben Cao Jing* (circa 200-250 CE), mention the medicinal and culinary use of mushrooms, indicating that their cultivation was already established by this time. The Chinese were among the first to cultivate *Lentinula edodes*, commonly known as shiitake mushrooms, using techniques that involved growing them on hardwood logs. This method laid the foundation for modern mushroom farming practices.
In Europe, mushroom cultivation emerged much later, with the first recorded attempts dating back to the 17th century. The French were pioneers in this field, particularly in the Paris region, where caves and quarries provided ideal conditions for growing *Agaricus bisporus*, the common button mushroom. By the 18th century, mushroom cultivation had become a commercial enterprise in France, with detailed manuals and guides being published to instruct farmers. These early European methods often involved the use of horse manure as a growing medium, a practice that remains common today. The spread of mushroom cultivation across Europe was gradual, influenced by the availability of suitable substrates and the cultural acceptance of mushrooms as food.
In contrast, the New World’s history of mushroom cultivation is relatively recent and largely influenced by European colonization. Indigenous cultures in the Americas had long foraged wild mushrooms, but systematic cultivation did not begin until the arrival of European techniques. In North America, commercial mushroom farming took root in the late 19th and early 20th centuries, particularly in Pennsylvania, where the climate and availability of caves resembled the conditions in Paris. The cultivation of *Agaricus bisporus* became dominant, and the industry rapidly expanded to meet growing demand.
While the Old World has a longer and more documented history of mushroom cultivation, the New World has contributed significantly to the industrialization and globalization of the practice. Advances in technology, such as the development of controlled environments and synthetic growing mediums, have allowed for year-round production and the cultivation of a wider variety of species. Today, mushrooms are grown on every continent, blending Old World traditions with New World innovations to meet the demands of a global market.
