Mushrooms are fungi that can grow on various substrates, including cow manure. While not all mushrooms grow on cow dung, one notable species that does is Psilocybe cubensis, commonly known as magic mushrooms. These mushrooms have a close association with cattle ranching and are often found growing on cow patties in tropical and subtropical climates. The unique conditions provided by cow manure, including nutrient-rich organic matter and low stomach acid levels, create an ideal environment for the growth of certain mushroom species. However, it is important to exercise caution when consuming mushrooms found in the wild, as proper identification and preparation are crucial to avoid potential health risks.

Psilocybe cubensis is the scientific name for mushrooms grown on cow manure
Psilocybe cubensis is found on cow (and occasionally horse) dung, sugar cane mulch, or rich pasture soil. In Asia, the species grows on water buffalo dung. The mushrooms appear from February to December in the northern hemisphere and from November to April in the southern hemisphere. Psilocybe cubensis grows naturally in tropical and subtropical conditions, often near cattle, due to the ideal conditions they provide for the growth of the fungus. The cow usually consumes grains or grass covered with the spores of P. cubensis, and the fungus will begin to germinate within the dung.
Psilocybe cubensis is relatively easy to cultivate indoors. First, spores are inoculated within sterilized jars or bags, colloquially known as grain spawn, containing a form of carbohydrate nutrient such as rye grains. After about a month, the spores fully colonize the grain spawn, forming a dense mycelium, which is then planted within a bulk substrate such as a coconut husk fiber and vermiculite mixture. Given proper humidity, temperature, and fresh air exchange, the substrate will produce fruiting Psilocybe cubensis bodies within a month of planting.
Small-scale cultivation of P. cubensis is often accomplished with "cakes" that colonize within jars but fruit inside specially designed tubs called "shotgun fruiting chambers". A study in 2009 showed that mushrooms grown in the dark had higher levels of psilocybin and psilocin compared to those grown in bright, indirect light, which had minimal levels. The transpiration and growth of the mushroom were heavily influenced by the humidity of the air, and misting enhanced both the growth and transpiration rates in the growing process of P. cubensis.

Cow dung is an ideal environment for fungi growth
There are several reasons why cow dung provides the perfect environment for fungi to flourish. Firstly, it is a rich source of nutrients for plants and fungi. This is because cow dung is essentially composed of partially digested grass that is broken down further by enzymes into simple molecules. These molecules are then absorbed and transported to the location where the fungi will grow, providing the necessary nutrients for their development.
Secondly, cow dung often contains very low levels of stomach acid. This is due to the unique digestive system of cows, which have four stomachs. The grass that cows consume is initially stored in the first two stomachs, the rumen and reticulum, and then regurgitated and rechewed before passing to the third and fourth stomachs, the omasum and abomasum. By the time the grass is fully digested and excreted, most of the stomach acid has been neutralized, resulting in dung that is relatively acidic-free. This makes cow dung a more hospitable environment for fungi growth compared to other types of animal waste.
Additionally, cow dung often provides the ideal climatic conditions for certain types of fungi to thrive. For example, the Psilocybe cubensis mushroom, also known as "magic mushrooms," is commonly found growing on cow dung in humid climates. This species has a preference for high humidity levels, typically above 85%, and can be found in tropical and subtropical regions. The dung provides the necessary moisture and warmth for the fungi to prosper.
Furthermore, the presence of cattle can facilitate the dispersal of fungal spores over vast distances. Cattle egrets, for instance, tend to walk alongside cattle, feeding on insects. As they walk through spore-laden vegetation and cow dung, they inadvertently transfer the spores to new habitats, aiding in the spread and growth of fungi species.

Manure is a typical fertilizer for mushrooms
Psilocybe cubensis grows naturally in tropical and subtropical conditions, often near cattle due to the ideal conditions they provide for the growth of the fungus. The cow usually consumes grains or grass covered with the spores of P. cubensis, and the fungus will begin to germinate within the dung. Mushrooms such as P. cubensis are relatively easy to cultivate indoors. First, spores are inoculated within sterilized jars or bags containing a form of carbohydrate nutrient such as rye grains. After about a month, the spores fully colonize the grain spawn, forming dense mycelium, which is then planted within a bulk substrate such as a coconut husk fiber and vermiculite mixture. Given the proper humidity, temperature, and fresh air exchange, the substrate will produce fruiting P. cubensis bodies within a month of planting.
In addition to P. cubensis, other types of mushrooms that have been observed growing on cow manure include Panaeolus antillarum, Panaeolus semiovatus, Coprinopsis lagopus, and Conocybe Tenera.
While cow manure can be a natural fertilizer for mushrooms, it is important to note that mushrooms growing on cow patties in the wild may be unsafe to consume due to potential bacterial contamination, such as E. coli. Commercially grown mushrooms, on the other hand, typically use sterilized manure to prevent such contamination.

Mushrooms grown in the dark have higher levels of psilocybin and psilocin
Psilocybe cubensis, commonly known as "magic mushrooms", is a species of psychedelic mushroom that grows naturally in tropical and subtropical conditions, often near cattle. The cow usually consumes grass covered with the spores of P. cubensis, and the fungus begins to germinate within the dung.
Psilocybe cubensis is relatively easy to cultivate indoors. First, spores are inoculated within sterilized jars or bags containing a carbohydrate nutrient such as rye grains. After about a month, the spores fully colonize the grain spawn, forming a dense mycelium that is then planted within a bulk substrate. Given the proper conditions, the substrate will produce fruiting Psilocybe cubensis bodies within a month.
Psilocybin mushrooms contain the prodrug psilocybin, which turns into the psychedelic psilocin upon ingestion. The effects of psilocybin mushrooms come from the combination of these two compounds. Psilocybin is broken down by the liver in a process called dephosphorylation, resulting in the compound psilocin, which is responsible for the psychedelic effects.
Interestingly, a 2009 study found that mushrooms grown in the dark had higher levels of psilocybin and psilocin compared to those grown in bright, indirect light, which had minimum levels. This indicates that light conditions can significantly impact the levels of these compounds in mushrooms.

Cow dung is a great source of nutrients for plants and fungi
Cow dung is an excellent source of nutrients for plants and fungi. It is a natural fertilizer that provides essential nutrients to support the growth of various organisms. The unique composition of cow dung, including its low stomach acid content, creates favourable conditions for the growth of certain fungi species.
One notable example is the Psilocybe cubensis mushroom, commonly known as "magic mushrooms" or "golden tops". This species has a particular association with cow dung and is often found growing on it in tropical and subtropical regions. The dung provides the ideal environment for the germination and development of these mushrooms.
The relationship between cow dung and Psilocybe cubensis is intriguing. Cattle, while grazing, ingest grass or grains covered with the spores of P. cubensis. As the cow digests the grass through its complex stomach system, the spores remain intact and are eventually excreted with the dung. Under the right conditions, the spores in the cow dung will germinate and develop into mushrooms.
Cow dung also plays a role in the dispersal of P. cubensis spores. Cattle egrets, birds that often accompany cattle, walk through spore-laden vegetation and cow dung, transferring the spores to new habitats during their migration. This process, known as zoochory, allows P. cubensis to propagate over a much wider range than it could achieve on its own.
In addition to P. cubensis, other types of mushrooms, such as Coprinopsis lagopus and Conocybe Tenera, have also been observed growing on cow dung. These mushrooms can be found in various environments, including fields, roadsides, and even in mountainous regions.
While cow dung provides a natural substrate for mushroom growth, it is important to exercise caution when encountering mushrooms in the wild. Proper identification and knowledge are crucial, as some mushrooms may be toxic. Additionally, mushrooms growing on cow dung could be exposed to potential contaminants, such as E. coli, which can cause food poisoning if consumed raw.
