Mushrooms are the fruiting bodies of fungi, which typically grow on land, in soil, or on plant material. They are not leaves themselves, but some mushrooms can grow on dead leaves. Fungi break down and eat dead organic material, such as leaves, fallen trees, and dead animals, and return nutrients to the soil.

What You'll Learn
Mushrooms are the fruiting bodies of fungi
Fungi reproduce by spreading tiny spores through the wind. If these spores land in a suitable location with enough water and food, they will grow into new mushrooms. They can also grow on living things, such as trees, and are called parasites in this case.
Fungi are extremely important to humans and nature. They return nutrients to the soil, allowing new plants to absorb them. They are also used in medicine and in the creation of food products such as blue cheese.
Fungi can be grown on dead leaves, but a pure leaf substrate will not produce a large flush of mushrooms. Supplementing with bran or increasing the spawn-to-substrate ratio can improve results. The leaves should have a certain amount of moisture to be digestible by the mycelium. Wine caps and blewits can also use leaves as part of their substrate, with wine caps being generally easier to cultivate.

Fungi break down and eat dead leaves
Mushrooms are a type of fungus, and fungi play a crucial role in breaking down and consuming dead leaves. This process is facilitated by mycelium, which are thread-like fungal structures that grow and eat the substrate, in this case, dead leaves. The leaves need to have a certain amount of moisture in them to be digestible by the mycelium.
Fungi, including mushrooms, are nature's decomposers, breaking down organic matter and playing a vital role in the ecosystem. They are responsible for the slow breakdown of leaf litter, preventing a buildup of dead leaves that could otherwise create an environmental problem. This process is not limited to leaves, as fungi also break down and consume other organic materials, such as fallen trees, contributing to the decomposition process in nature.
In a natural setting, mushrooms and fungi have been growing and interacting with their environment for millions of years. They have complex relationships with their surroundings, including bacterial interactions that are not yet fully understood by scientists. For example, wine caps, a type of mushroom, grow best outdoors in a substrate of hardwood chips, but they also require bacterial interaction to produce well.
The process of fungi breaking down and eating dead leaves is not limited to wild mushrooms. In fact, some people cultivate mushrooms on dead leaves as a fruiting substrate. While a substrate of pure leaves may not yield a large flush of mushrooms, supplementing with bran or using a huge spawn to sub-ratio can improve results. Additionally, the nutritional content of the substrate is crucial for the development of medicinal and nutritional benefits in the mushrooms.

Mushrooms can grow on dead leaves
Mushrooms are a type of fungus that can grow on dead leaves. Fungi are saprophytes, which means they break down and digest nutrients from dead organic matter, including leaves, and use them for growth. This process is essential in nature, as it prevents a buildup of dead leaves.
Some mushrooms that can grow on dead leaves include blewits, Stropharia rugosa annulata, and wine caps. Wine caps, for example, are commonly cultivated outdoors in a patch and require bacterial interaction to produce well. They are often grown using leaf mulch from non-botanically related plants.
To successfully grow mushrooms on dead leaves, the leaves must have a certain level of moisture to be digestible by the mycelium, the part of the fungus that grows and spreads. Additionally, the leaves should be composted or shredded to break down the lignin into digestible nutrients.
While some mushrooms can utilize dead leaves as a substrate, a pure leaf substrate may result in a smaller yield, producing only one or two mushrooms. Therefore, it is often recommended to supplement the leaf substrate with other materials, such as bran, brown leaves, meadow grass, or hardwood chips, to increase the nutritional content and promote better growth.

Mushrooms can be cultivated using dead leaves
Mushrooms are a type of fungus, and some fungi digest nutrients from dead organic matter, such as leaves, fallen trees, and compost heaps. These fungi are called saprophytes. Mushrooms can be cultivated using dead leaves, and there are a few ways to do this.
One way is to use wine caps (Stropharia rugosoannulata) and grow them on the ground. Wine caps are a great mushroom to grow, with little chance for failure. They are large, flavorful, and will tolerate the high temperatures of summer. To cultivate wine caps, place a wine cap bed in an area that's shaded for most of the day. Remove any green matter so that all the debris in the bed is dead. You can rake a compost pile to the side, exposing the bare ground beneath it, and start your bed there. Leaving twigs and dead leaves is fine, as the wine cap mycelium will colonize that as well and use it for additional nutrition. Wine caps grow best on a substrate of mostly hardwood chips, and they are mostly grown outside because they require some form of bacterial interaction to produce well.
Another way to cultivate mushrooms using dead leaves is with blewits. Blewits grow naturally on leaf litter on the forest floor and are typically a fall mushroom. Starting a bed of blewits in leaf litter is an easy way to get great edible mushrooms after the mushroom season is over. They can appear by the hundreds at times and are a favorite of experienced mushroom hunters. For fall inoculation, start with trimmed stalk ends from freshly collected mushrooms and place them in your leaf pile. For summer inoculation, find a shaded area to start the bed and rake away debris to expose the soil surface. Water the bed well to give it a nice source of humidity as the mycelium develops. Cover the spawn layer with another layer of leaves and then water the bed, being careful not to oversoak it and drown the mycelium.
In addition to wine caps and blewits, other mushrooms can also be cultivated using dead leaves. Oysters, for example, can grow off of leaves and pine needles. When using leaves as a substrate, it's important to ensure that they have a certain amount of moisture in them to be digestible by the mycelium. Leaves can be supplemented with bran or spawn to increase the yield.

Mushrooms can grow on living trees, parasitised by fungi
Mushrooms are the visible fruiting bodies of fungi, which may attack living tissue but usually feed on dead organic matter, such as rotten wood, leaves, and fallen trees. They break down organic matter, returning its constituent parts to the soil, enriching it. However, when mushrooms are seen growing on a living tree, it is a warning sign, as the tree is being parasitized by a fungus under its bark.
Fungi need to source nutrients from their surroundings to grow, and parasitic fungi require living hosts to obtain these nutrients. Over time, they infect the entire host, causing it to die. Some parasitic mushrooms include the cauliflower mushroom, which feeds on the roots of coniferous trees, and the Chaga fungus, often found on birch tree trunks in cold climates.
Some mushrooms, like the coral tooth fungus and the bearded tooth mushroom, prefer to grow on dying or fallen trees. However, the lion's mane mushroom, a cousin of the former, grows on trees that are still standing. The crown coral mushroom is another example of a fungus that grows on living trees, specifically deciduous trees, and, on rare occasions, coniferous trees.
While mushrooms may appear to grow on trees, the mushroom life force, or mycelium, is inside the tree, waiting for the right conditions, such as temperature, rain, and seasonality, to fruit. These mushrooms are not parasitic but form a mutualistic relationship with the trees, helping the plants absorb water and minerals in exchange for nutrients.
