Mushrooms are the fruiting bodies of fungi that exist in the soil. Fungi help break down decaying matter, and after heavy rain, they begin to bloom, causing mushrooms to appear above ground. Mushrooms are rarely a bad sign in the garden, except when seen growing on living trees, which usually indicates rotting. Mushrooms often emerge in lawns and gardens after the first rains and cooler weather of fall. They are one of the oldest plants on Earth, and their appearance can be quite sudden and surprising.

Mushrooms are the fruiting bodies of fungi
Mushrooms are the reproductive organs of fungi, which are responsible for dispersing spores to enable the fungi to spread and grow in new locations. Fungi are an essential part of the biological cycle, breaking down organic matter like old leaves, wood, and other detritus that accumulates on the ground. This process of decomposition results in the production of humus, a nutrient-rich substance that enhances the soil's fertility by adding essential nutrients and improving its water retention capabilities.
Mushrooms are not true plants, but rather belong to a distinct kingdom of their own, separate from plants and animals. They are the visible fruiting bodies of fungi, which exist primarily beneath the soil's surface or within decaying organic matter. The appearance of mushrooms above the ground is often triggered by rainfall, particularly after heavy rains. This phenomenon occurs because the mycelium, a network of thread-like structures, absorbs water, leading to rapid cell expansion and the subsequent emergence of mushrooms.
The growth of mushrooms can be influenced by various factors, including soil health and nutrient availability. Healthy soil, rich in organic matter and nutrients, can promote the growth of certain types of fungi and, consequently, the formation of mushrooms. Additionally, the presence of specific nutrients in the soil can attract chickens, whose droppings further contribute to the growth of fungi and the production of mushrooms.
While mushrooms are generally not harmful in gardens and lawns, their presence in large masses or near low-water plants may indicate an issue with the plant's health or improper soil drainage. It is also important to note that mushrooms can be extremely toxic to dogs, so pet owners should exercise caution and consider removing them from areas accessible to their canine companions.
The relationship between rainfall and mushroom growth is complex and intriguing. The appearance of mushrooms after rain is a testament to the dynamic nature of the natural world and the intricate interplay between weather patterns and biological processes. Understanding the factors that influence mushroom growth can enhance our appreciation of the delicate balance that exists within ecosystems.

Mushrooms break down decaying matter
Mushrooms are more commonly seen after rainfall. While they are rarely a bad sign in the garden, they can indicate something is wrong if they appear in large masses or areas with low-water plants. They can also be harmful to dogs, so it is important to keep pets away from them.
Mushrooms are the fruiting bodies of fungi that exist in the soil. They play a crucial role in ecosystems as decomposers, breaking down decaying organic matter and creating rich, nutrient-filled soil. This process is known as decomposition, and it involves the breakdown of dead organic material into simpler forms like carbon, oxygen, nitrogen, or phosphorus.
Fungi, including mushrooms, move through the soil by taking in the soil in front of them and passing it through their bodies. They physically break down organic matter through their digestive systems. In addition, they release chemicals to decompose plant and animal matter, which they then absorb as nutrients.
Mushrooms are nature's decomposers, helping to clean up dead matter and make nutrients available for plants to use. They feed on dead plant material like leaf litter and wood, animal carcasses, and scat. Without these fungi, there would be a buildup of decaying matter, leading to an imbalance in the ecosystem.

Mushrooms are rarely a bad sign
However, it is important to note that mushrooms can be extremely toxic to dogs. If you have pets, it is advisable to rake them out of your lawn or garden beds and add them to your compost pile. While generally not harmful, if mushrooms appear in large masses or in areas with low-water plants, it may be a sign of improper soil drainage or other issues.
One exception to the rule that mushrooms are rarely a cause for concern is when they are seen growing on living trees, as this usually indicates that there is some rotting occurring inside the tree. Another exception is fairy ring mushrooms, which appear as a circle in the lawn, typically in the spring. These mushrooms create dense mats of mycelium that expand and choke out the grass, requiring significant effort to remove.
Overall, mushrooms are an important part of the biological cycle, breaking down organic matter and adding nutrients to the soil. They are a common sight after rainfall, and while they may sometimes indicate an underlying issue, they are usually not a cause for concern.

Mushrooms can be toxic to dogs
Mushrooms are more common after rainfall. This is because the mycelium pumps water into the primordia, causing rapid cell expansion. While mushrooms are not usually harmful in gardens, they can be extremely toxic to dogs. Out of the 10,000 species of mushrooms in the United States, about 100 are toxic. It is very difficult to identify mushrooms and determine which are safe and which are poisonous. If your dog eats an unknown mushroom, consider it an emergency. Wild mushrooms can be extremely toxic to dogs, and it's nearly impossible to tell safe from dangerous varieties without expert knowledge. Even a small bite of a toxic wild mushroom can be dangerous or fatal.
If your dog has ingested a wild mushroom, seek immediate veterinary care. Call a veterinary emergency hospital right away, even if your dog isn't showing symptoms yet. Quick action can save your dog's life in mushroom poisoning cases. If possible, collect a sample of the mushroom (using gloves and a paper bag) to help with identification. Bring the mushroom sample if you have one, and be ready to describe all symptoms and the timeline of events to the veterinary team.
Depending on the specific mushroom ingested, mushroom poisoning in dogs can cause vomiting, diarrhoea, tremors, seizures, as well as liver and kidney failure. The deadliest mushroom species is Amanita, which is absorbed by the stomach when ingested. The toxins (amanitins) travel to the liver, where they can kill liver cells and cause liver failure. The amanitins are then excreted by the kidneys, which can result in subsequent kidney failure. Other species of toxic mushrooms are often grouped based on the clinical reactions they cause. For example, a relatively large group of mushrooms can cause gastrointestinal issues such as vomiting and diarrhoea, which can lead to significant dehydration and decreased heart rate.
There is no specific antidote for mushroom poisoning in dogs. Treatment varies depending on the type and amount of mushroom ingested. If your pet ate mushrooms within the last two hours, your veterinarian may induce vomiting at the hospital as a means of decontamination. If the mushroom cannot be identified or is identified as highly toxic, your dog will need to be hospitalized and started on IV fluids for hydration and supportive care.

Mushrooms emerge from old buried organic material
Mushrooms are the fruiting bodies of fungi that exist in the soil. Fungi help break down decaying organic matter, such as old leaves, wood, needles, and other organic detritus that fall to the ground. They reproduce by sending up mushroom caps, which we often see in lawns, gardens, and forests after heavy rainfall.
The white threads that run through piles of old leaves or rotting wood are the mycelium of the fungi. These threads use organic chemical processes to break down organic material and return it to the soil as humus, a rich, brown substance. Once the mushroom caps rise from the soil, they open and release millions of spores from the gills underneath. These spores are then carried by the wind to new locations, where they can grow into new fungi.
Mushrooms often emerge from old buried organic material when the right conditions occur for them to fruit. For example, if you or a builder buried wood debris from a tree-cutting project, the fungi will naturally grow into it. When the conditions are favourable, such as after heavy rain, the mushrooms will appear above ground. They may stay for one season or many, depending on the environmental factors.
While mushrooms are generally not harmful in gardens and can indicate healthy soil, they can be a concern if they grow in large masses or near low-water plants. Additionally, some mushrooms, such as the puffball mushroom, can be extremely toxic to dogs. Therefore, it is essential to identify the mushroom species before consuming them or allowing pets to come into contact with them.
