Day of the Mushroom – April 16, 2025

The Day of the Mushroom celebration is celebrated on April 16 and honors all things fungi. The fleshy, spore-bearing fruiting body of a fungus, which can grow anywhere above ground, on soil, or its food source, is known as a mushroom. The white button mushroom, which is grown, is the standard fungus to be called a mushroom. Therefore, fungi with a stem, cap, and gills on the underside of their cap are those to which the term “mushroom” is most frequently applied. The name “mushroom” is also relevant to describing the fleshy fruiting bodies of other Ascomycota because it is used to describe a range of different gilled fungi that may or may not have a stem.

History of Day of the Mushroom

Since they first appeared in early European communities, it is generally assumed that people have been gathering mushrooms since the beginning of time, possibly even in prehistoric times. Truffles and other types of mushrooms were prized in classical Greece and Rome. American author Cynthia Bertelsen claims in her book “Mushroom: A Global History” that both well-known historical authors, Pliny the Elder and Aristotle, wrote about fungus. She also claims that the Roman philosopher Galen wrote several paragraphs on the collection of wild mushrooms. Cynthia Bertelsen goes on to add that it is likely that China and Japan were the first places to cultivate mushrooms as early as 600 A.D.

But it took time for Americans to accept and become accustomed to mushrooms. In the cookbook “The Virginia Housewife,” mushrooms are mentioned for the first time in America (1824). Campbell’s Cream of Mushroom Soup, a classic American staple for casserole recipes, was created in the 1930s. Bertelsen adds that there may be archaeological proof of the spiritual usage of mushrooms as early as 10000 B.C. There is proof that various cultures, including the Ancient Greeks, the Mayans, the Chinese, and the Vikings, among many others, used hallucinogenic mushrooms.

Humans now consume edible mushrooms regularly, which has greatly boosted the agricultural and agro-economic development of the areas where they are grown. Around half of all farmed edible mushrooms are produced in China, which also accounts for six pounds of yearly mushroom consumption per person among the world’s 1.4 billion inhabitants. With an estimated 194,000 tonnes of yearly edible mushroom exports, Poland was the leading exporter of mushrooms in 2014.
