Are Mushrooms Plants? What is a mushroom?

A fascinating question you may have asked yourself is, “Are mushrooms plants?” While they have a plant-like appearance and grow similarly to plants, it may come as a surprise to learn that they are not plants at all!

Mushrooms are classified as part of the Kingdom Fungi, whereas plants are classified as part of the Kingdom Plantae. Yes, while mushrooms and other fungi grow very similarly to their plant relatives, they do not produce their own food via photosynthesis, among other interesting characteristics.

While mushrooms typically grow in close association with plants, these fascinating fungi have their own unique growth and survival strategies. Continue reading to learn more.

Mushrooms: Mysterious Fungi

What Kind of Mushroom Is It?

To begin, we must define a mushroom. We have established that they are not plants, but did you know they are more closely related to animals?

Yes, these tiny fungi are more closely related to humans than to trees or flowers.

However, it was once believed that mushrooms were close relatives of plants, which explains why the names given to mushroom parts are similar to those given to plant parts.

As with plants, mushrooms produce fruit (similar to an apple) as well as seeds called spores. The mushroom’s actual body is called mycelium, and each component is microscopic.

The mushroom’s “cap” contains thousands of microscopic spores, while the stalk contains the mushroom’s nutrients.

One of the most fascinating aspects of mushrooms is that the “mushroom” that you see sticking out of the ground or the side of a tree is only a fraction of the total size of the mushroom.

The mushroom that we see above ground is actually the mushroom’s fruit. In the wild, some mushroom species can spread their body out over hundreds of square miles.

The mushroom’s body contains and stores nutrients as well as other necessary compounds for growth, and when sufficient amounts are accumulated and the conditions are just right, the fungi begins to fruit and produce the mushrooms visible above ground.

It may surprise you to learn that the majority of fungi, including mushrooms, construct their cell walls entirely out of chitin.

Chitin is the same material found in insects and other arthropods’ hard outer shells. Thus, that small, squishy mushroom is composed of the same material as an ant!

How do Mushrooms Proliferate?

Because mushrooms are not plants, they lack chlorophyll and thus do not undergo photosynthesis.

Rather than that, they obtain nutrition by consuming and metabolizing dead organic matter, such as trees and other plants. They degrade and “eat” them, similar to a compost pile.

While these tiny fungus “consume” their food, they lack a stomach to digest it.

They digest their food by breaking it down into simple molecules that are easily absorbed using acids and enzymes. This is referred to as composting.

Because they are not photosynthesis dependent, they obtain their nutrients from other sources. Water is essential for plants and animals, but especially for mushrooms. They require water to grow their fruit.

Because mushrooms lack a skin, they can easily lose water to the atmosphere. That is why they thrive in high humidity climates; the more humid the air, the more water vapor there is.

If the humidity level around the mushroom is insufficient. The mushroom’s cells will then dehydrate quicker than water can be pushed into the young mushroom body, and the mushroom will shrivel and die.

Mushrooms also lack thermal regulation, which means they are unable to regulate or maintain their body temperature. This implies that they flourish in warmer climates.

One fascinating fact is that recent scientific studies have demonstrated that mushrooms actually help to slow down climate warming in northern forests.

In an era when global warming is a constant threat, this diminutive fungus may prove beneficial in finding a solution.

Mushrooms and Water

While water is essential for mushrooms, this does not imply they can live fully submerged!

The tiny fungus, like animals, requires oxygen to survive, despite the absence of lungs. Alternatively, they exchange gases with the surrounding air directly through their cells.

This means that if a mushroom’s body is submerged in water, the fungi will “drown,” just as humans do. Because oxygen cannot be exchanged, the mushroom will suffocate to death.

It is remarkably similar to the mushroom’s real fruit. If the environment is excessively moist and the humidity is too high, the extra water will obstruct gas exchange and will choke the growing mushroom fruit to death.

On the other hand, if the air is excessively dry, the little fruit will lose too much moisture and shrivel up and perish.

A proper mix of humidity, the appropriate nutrients and chemicals, and water will result in a plump, healthy mushroom fruit while also allowing the mushroom body to survive and develop.

Mushrooms Are Divided Into Three Types

Due to the close relationship that mushrooms and other fungi have with plants, fungi can be classified into roughly three categories.

Saprophytes would be the first category. These fungi thrive on decomposing organic matter such as trees, leaves, and plant roots.

They extract carbon dioxide and minerals from this matter and use them to grow. This category contains a diverse range of gourmet and medicinal mushrooms.

The following category is called Parasites. These parasitic creatures feed on live organisms such as trees and other plants, extracting their nutrition.

These mushrooms are dubbed “murderers” because of their tendency to steal nutrition. The Saprophytes clean up the remnants of the plant they are feeding on when it dies.

Mycorrhiza is the final category. This class of organisms coexists symbiotically with the roots of living trees.

They consume sugars and nutrients from the tree while returning minerals and essential elements to their host, thereby increasing the root system of the host. This species of mushroom is almost entirely found in nature.

Mushrooms Proliferating Overnight?

The majority of people are perplexed as to how mushrooms may emerge magically while we sleep. To be honest, the rationale behind this is pretty interesting.

To begin, as previously mentioned, mushrooms store chemicals for when they are ready to fruit, and the majority of mushrooms only fruit once a year.

This implies that mushrooms will have a significant amount of stored reserves available to sustain the mushroom fruit. Second, mushrooms grow in an opposite manner to plants and animals.

While animals and plants undergo cell division to increase in size, mushrooms undergo cell enlargement. This mechanism causes the mushroom cells to quickly expand in size.

Not only is this procedure much quicker than cell division, but it also consumes a negligible amount of energy. In essence, a mushroom may grow in size at the rate at which water can be pushed into its cells.

That explains how a mushroom can develop nearly overnight from apparently nothing!

Mushrooms and Culinary Arts

There are many varieties of mushrooms, and fortunately, the most of them are not only tasty but also very nutritious when eaten!

They are a good source of vitamin B, particularly riboflavin and niacin, and they have the highest protein content of any vegetable.

As a result of these factors, it is unsurprising that mushrooms are employed in a range of delectable recipes. From Portobello to Morel mushrooms, there are many little fungi that may enhance the flavor of a dish.

Why Are Mushrooms a Sign of Healthy Soil?

We will discuss what mushrooms do, how they develop, and how to prevent or control their growth.

Mushrooms: A Purposeful Fungus

When people hear the term mushroom, they immediately think of its plant variation, fungus, and when they think of “fungi,” they often think of one specific kind of fungi: mold (especially white powdery mold and yellow/brown downy mold). While those types of fungi are typically parasites, mushrooms generally assist plants in exchanging nutrients or in reintroducing nutrients into the soil.

Reproduction and Growth of Mushrooms

Mushrooms do not develop in the same way that plants do. To proliferate, their spores must adhere to a nutritional source, such as the roots of a plant, a dead plant, or a dead animal. They do not reproduce through seeds, but as long as there is a wind or some other means to transfer spores onto a nutritional source, that is all they need. Because they lack chlorophyll, they depend on the nourishment of a plant (living or dead) to survive. That is not to say that mushrooms are suffocating your plants. Quite the contrary: the majority of mushrooms are symbiotic with plants, especially at the root level.

Mushrooms provide your plants with the nutrients they need to create the sugars the mushroom feeds on, allowing them to develop and get the finest nutrition possible. Saprophytism occurs when a mushroom or group of mushrooms assists in the decomposition of something and then returns it to the soil. Whether it is fading areas of your lawn, decaying roots under the soil, or dead plants and animals (and their waste), mushrooms can absorb nutrients from a decomposing source and return them to the soil in a manner that bacteria and insects cannot.

Generally, Mushrooms Indicate Healthy Soil As previously said, if you are certain there are no mushrooms or fungal spores in your growing area but still observe mushrooms growing, you may be alarmed—and we do not blame you. Unlike mold, which may indicate stagnation, mushroom development from your soil can indicate rather healthy soil. How?

Bear in mind that since mushrooms lack roots, they must feed on the roots of your plant or decomposing nutrient sources in the soil. If you transplant rooted plants into fresh soil and subsequently see mushrooms emerging from the soil, there is a high likelihood that mushroom spores were present in your soil and had the opportunity to feed on your plants. If you see mushroom development before your seed(s) emerge, it is possible that spores were stuck to something in your soil (often a wood chip) and began to grow.

Mushrooms like cold, damp, and humid environments with little light. Mushrooms will grow out of the sides of fabric grow bags for just this reason: when you feed your plants, the bags get wet, they sit in a humid environment, and temperatures are sure to reach about 50-60°F at some time. If the environment is conducive to mushroom development, all that is required is a spore and something to cling to, and you will observe mushrooms emerging from the earth.

Eliminating Mushrooms from Your Garden While mushrooms are generally innocuous to plants, they are not desired in all gardens for a variety of reasons. Certain mushrooms may function as insecticides when consumed by insects, but they can be very harmful if consumed by our pets or by anybody who is unaware.

If you are attempting to prevent them in the future, you may also wish to eliminate them immediately upon seeing them. Mushrooms reproduce by releasing spores, which adhere to a source of nourishment (for example, a wood chip in your soil or the roots of a growing plant) and begin to develop. To prevent accidental mushroom development, attempt the following three steps:

1) Destroy the ecosystem. Mushrooms like cold, humid, and moist environments, therefore if you increase the temperature in your garden, decrease the humidity, and temporarily reduce watering, they will dry out and become unable to develop.

2) Pick them off as soon as you notice them. Picking mushrooms will not damage your plants, so if you do not want them in your soil or around your plants, just take them off and discard them.

3) Begin composting and cultivating your own soil. Pre-mixed soil contains a variety of unknown contaminants, including spores. If you are unsure of what is in your soil, determining whether or not you have the makings of mushrooms is a dice roll. Making your own soil from decomposed wastes is the safest method to ensure you have the nutrients necessary for mushroom cultivation.

Additional reviews

Lisa declares:

That is analogous to asking why a flame is not considered an animal. For the simple reason that it is not.

It is not linked to plants genetically; it is a member of its own kingdom of life, the fungus. Its cells are unique in comparison to those of plants. It lacks the capacity to develop in the way that plants do; it lacks photosynthesis and chlorophyll. A mushroom is not even a self-contained creature. It is the fruiting body of the organism itself, which is usually seen growing in dirt, leaf litter, or rotten wood.

To be honest, they bear no resemblance to plants. The only thing they have in common is that they are both unable to walk.

John says:

Mushrooms, and by extension fungus, lack a number of characteristics associated with plants. Plants, with very few exceptions, possess chlorophyll, robust cellulose-based walls, and intricate tissues. Fungi lack all of these characteristics and are therefore more appropriately classed as colony creatures than multicellular organisms. They lack the capacity to synthesize food from sunlight, have chitin-based cell walls, and lack complex tissues.

Marry says:

Generally, untrue. If you look at the early Earth, the majority of the necessary ingredients for life were discovered in the seas. The land included minerals in a variety of oxidation states. Enter the fungus, which were capable of decomposing minerals and forming soils (as feces), thus creating the current circumstances conducive to plants.

As more evidence from the ancient record becomes available, it is becoming clear that humans are more closely connected to fungus than plants. Which is why, if you have ever attempted to cure a toenail fungus, you know how tough it may be to eradicate without first dying (as we animals share similar vulnerabilities).

Classifying fungi (mushrooms are fungus) has proven challenging. On Earth, about 3+ billion years of life have passed, leaving minimal fossil record during the first 3 billion years. What occurred when is a wild guess. However, considering the intricacy of plant (oxygen producing) DNA, humans are closer to mushrooms.

Several speculative ideas include panspermia, which postulates that fungus arrived on Earth through comets. It is a riddle inside a mystery.

Aside: I once had a pet slime mold that took up residence in a studio space I had just vacated but retained access to. (Congratulations on your botany major!) Knowing that my time in the area was short and that I had unrestricted access to sawdust and wetness, I had some fun before being forced to leave. The slime mold showed animalistic characteristics, which have now been eradicated, but it was nonetheless a pet for a while.

Mona declares:

Mushrooms are classified as fungus. Apart from plants and animals, they belong to their own kingdom. Fungi get nutrients differently than plants and mammals. In general, plants produce food via the sun’s energy, while animals consume and subsequently digest their food. Fungi, on the other hand, do not do either: their mycelium develops in or near the food source, secretes enzymes that digest the food externally, and then absorbs the nutrients consumed. These broad strokes are made; some creatures are classified into their respective kingdoms on the basis of characteristics other than their eating patterns.

Sara declares:

Mushrooms are not considered plants! They were recently found to be more closely linked to mammals. However, fungi, especially mushrooms, were formerly considered close cousins of plants. Mushrooms and mushroom derivatives are very beneficial to health. Innature health’s natural mushroom products are incredible.


Not only have we learned why mushrooms are not plants, but also about the fungus’s inner workings and how this species grows and thrives.

In the absence of sunlight, mushrooms have developed their own uniquely suited method of nutrition acquisition.

Whether it is the Mycorrhiza, which forms a symbiotic connection with its host, the Saprophyte, which feeds on dead plants, or the Parasite, which steals nutrients, mushrooms have adapted wonderfully to their environment.

Numerous additional parallels exist between mushrooms and plants. Both are consumed as food and are used as components in our meals.

Mushrooms, like plants, provide us with vitamins and are a delectable addition to nearly any meal.

And, like plants, mushrooms may be found growing wild in woods or in our backyards, or they can be cultivated and nurtured in gardens and greenhouses.

The advantages and complexities of this little fungus are not only fascinating, but also helpful to our lives and the environment in many ways.
