Fungi are traditionally considered heterotrophs, relying on other organisms for metabolism. They exhibit a high degree of metabolic versatility, allowing them to utilise a diverse range of organic substrates for growth. Fungi encompass a wide variety, including mushrooms, moulds, yeasts, and other less mushroom-like forms. While all mushrooms are fungi, not all fungi are mushrooms. Mushrooms are just one form of fungal growth, and they play a similar role to flowers or fruits in plants. This diversity within the kingdom of fungi makes exploration intriguing and challenging, requiring keen attention to detail for accurate identification.

What You'll Learn
Not all fungi are mushrooms
While all mushrooms are fungi, not all fungi are mushrooms. Mushrooms are only one form of fungal growth, and they belong to the phylums Basidiomycota or Ascomycota. The Basidiomycota phylum includes the most commonly known basidiocarps, which are mushrooms. However, this phylum may also take other forms. The Ascomycota phylum, on the other hand, includes structurally similar hooks in the ascomycetes.
Mushrooms play a similar role to flowers or fruits in plants for those fungi that produce them. The underside of a mushroom's cap is often where spores are formed, called the hymenial layer. These spores are similar to pollen or seeds and can number in the trillions. The rest of the fungal organism typically lives in the soil, wood, or other materials and is composed of thread-like strands called mycelium. An individual mycelium can grow quite large, with a documented case covering more than 1,500 acres in Oregon.
Not all fungi have the characteristic cap and stem of mushrooms. For example, Turkey Tail, which grows out of the trunk of a fallen tree, does not resemble a mushroom. Similarly, the Tinder Polypore, which grows from the side of a healthy tree, does not have a typical mushroom appearance. These examples highlight the diversity within the world of fungi, where some species resemble mushrooms, while others have unique forms.
The variety of shapes and structures among fungi underscores the importance of mindfulness and attention to detail when identifying different species. While some fungi grow in soil, others grow on living trees or rotting wood. Understanding the substrate, or the material from which the fungus is growing, can provide valuable insights into its ecology and aid in identification. Additionally, creating a spore print by placing the cap of a fresh mushroom on a sheet of paper can be a helpful identification technique.

Mushrooms are a type of fungus
Mushrooms, specifically, play a similar role to flowers or fruits in plants for those fungi that produce them. They are the fruit bodies that develop for the dissemination of spores. The spores of mushrooms are microscopic and similar to pollen or seeds. These spores are often produced on the underside of the mushroom cap, known as the hymenial layer.
Most mushroom-producing fungi belong to the phylums Basidiomycota or Ascomycota. The Basidiomycota phylum includes well-known mushrooms such as the button mushroom, oyster mushrooms, shiitake, porcini, and chanterelles. The Ascomycota phylum includes prized morels and true truffles.
Mushrooms have been used for food and medicine for thousands of years, particularly in China and Japan. For example, regular consumption of oyster mushrooms has been linked to reduced cholesterol. However, it is important to distinguish between edible and poisonous mushrooms, as some species, such as Amanita, can be toxic or even hallucinogenic.
Identifying mushrooms can be challenging due to the diverse appearance of different species. Therefore, it is crucial to pay attention to small details, such as the presence of an annulus or a volva, and seek expert guidance before consuming any wild mushrooms.

Identifying mushrooms and other fungi
While all mushrooms are fungi, not all fungi are mushrooms. Mushrooms are fungi with a stem (stipe) and a cap. The stipe can be ornamented with an annulus (a skirt of tissue around the circumference of the stipe) or a volva (a sack of tissue at the base of the stipe), or both. If the mushroom has a cap, the underside is often where spores are formed, called the hymenial layer.
To identify mushrooms and other fungi, it is important to be detail-oriented. Fungi are incredibly diverse, and different species can look very similar. One should note the substrate, or the material that the fungus is growing from, as this can help understand its ecology and lead to identification. For example, some fungi only grow in soil, some on living trees, and some on rotting wood. One can also produce spore prints by laying the cap of a fresh mushroom on a sheet of paper and waiting a couple of hours. Many field guides are organised by spore colour, so this is an important trait to note. It is also important to look for individuals at different stages of development, as the same species can look different at these different phases, and young specimens can be especially misleading.
Mushrooms in the Pholiota genus typically grow in large clumps on wood and are characterised by their dry caps that are often covered in scales or fibres. Some species have caps that are sticky to the touch, while others have very scaly caps. Mushrooms in the Psathyrella group are typically small to medium-sized fungi characterised by their fragile, thin caps and slender stems. They often have grey or brown gills that may be attached to the stem or slightly free, and most have conical caps. They often grow in clumps. Mushrooms in the Stropharia genus are medium to large saprophytic fungi, characterised by their often colourful, sticky caps, and gills that turn dark as they mature due to spore production. Many species in this genus have a distinctive annulus (ring) on their stems.
Mushrooms in the Melanoleuca genus are medium to large-sized fungi commonly found in grasslands, meadows, and wooded areas. They have white spore prints, smooth caps that often appear flat with a central umbo, and come in shades of white, beige, or brown. They have fibrous stems that lack both a ring and a volva. Mushrooms in the Pleurotus genus, often called "oyster mushrooms," are characterised by their broad, fan-shaped or oyster-shaped caps.
Mushrooms in the Lycoperdon, Calvatia and Bovista genuses, also known as puffballs, are characterised by their round, ball-shaped fruiting bodies that release spores through an opening at the top. They are found in a variety of habitats, including grasslands, forests, and disturbed areas, and can range in size from a few centimetres to over a metre in diameter. Polypores are a group of fungi that have a distinct fruiting body with pores on their undersurface. They are also known as bracket fungi because their fruiting bodies often resemble shelves or brackets that grow on trees or logs. Tooth fungus is characterised by their tooth-like projections on the underside of their caps, instead of traditional gills. They often have a fleshy, funnel-shaped cap, and can range in colour from brown to orange to yellow.
Cup fungi are a group of fungi characterised by their cup-shaped fruiting bodies, which resemble small, often colourful bowls or cups. They typically belong to the Ascomycota phylum and are commonly found growing on decaying wood, leaf litter, or in soil.

Mushrooms' role in plants is similar to flowers or fruits
Mushrooms are a type of fungus that grows in the soil or on decaying organic matter. They are not plants, as they lack chlorophyll and cannot photosynthesize. Instead, they rely on organic matter for their nutrition. The part of the mushroom that we see above the ground is the fruiting body, which produces spores used for reproduction. This is similar to the role that flowers or fruits play in plants. Flowers in plants are reproductive structures that produce seeds or pollen, while fruits are the product of fertilized flowers and contain seeds. Mushrooms, on the other hand, produce microscopic spores that are similar to pollen or seeds. These spores are released from the fruiting body and can be dispersed over long distances by wind or water. When they land on a suitable substrate, they germinate and grow into new mushrooms.
While mushrooms and plants have different methods of obtaining nutrition, they share some similarities. Both are multicellular organisms that play important roles in the ecosystem. They both have protective cell walls that provide structure and support. Additionally, both plants and mushrooms have been used for medicinal purposes. For example, some types of mushrooms, such as shiitake, maitake, and reishi, have been shown to have immune-boosting properties and potential anti-cancer effects.
One significant difference between mushrooms and plants is their impact on the atmosphere. Plants play a vital role in producing oxygen through photosynthesis, absorbing carbon dioxide from the atmosphere and releasing oxygen. In contrast, mushrooms do not produce oxygen and do not have a direct impact on the atmosphere. Instead, they contribute to the ecosystem by breaking down organic matter and recycling nutrients, which helps maintain soil health and supports the growth of other plants.
The relationship between mushrooms and plants can be complex. While some mushrooms may parasitize plants, many mushroom-producing species have a special, symbiotic relationship with particular plant species. These relationships, known as "mycorrhizal," highlight the interconnectedness of mushrooms and plants in the natural world.
In conclusion, while mushrooms and plants are distinct organisms with different characteristics, the role of mushrooms in producing spores and contributing to the ecosystem is similar to the role of flowers and fruits in plants.

Mushroom hunting and identification
Mushroom hunting, mushrooming, mushroom picking, mushroom foraging, and similar terms describe the activity of gathering mushrooms in the wild. This is typically done for culinary purposes, although medicinal and psychotropic uses are also known. Expert analysis is required to distinguish between useful and poisonous species. Mushroom hunting is popular throughout most of Eurasia and Australia, as well as in temperate regions of North America.
In Slavic and Baltic countries, mushroom picking is a common family activity. In Southern Lithuania, mushroom hunting is considered a "national sport". They even host a Mushroom Festival ("Grybų šventė") in Varėna, including a mushroom hunting championship. In the U.S., mushroom picking is popular in the Appalachian area and on the west coast from San Francisco Bay northward, in northern California, Oregon, and Washington, and in many other regions.
Nuclear fallout from the Chernobyl disaster is an important issue concerning mushroom picking in Europe. Due to the wide spread of their mycelium, mushrooms tend to accumulate more radioactive caesium-137 than the surrounding soil and other organisms. State agencies monitor and analyze the degree of radionuclide accumulation in various wild species of plants and animals.
For beginners, morels are among the easiest to find and identify. They have a distinctive brain-like appearance and can only be confused with false morels, which don't look like the real thing upon close inspection. Matsutakes are among the most difficult to identify by sight alone, but their distinct smell—often described as “cinnamon and gym socks”—is a clear giveaway. The best way to avoid poisoning is to get familiar with the characteristics of the specific mushrooms you’re looking for, learn when and where they’re available, and ignore those you cannot identify.
A common identification technique is the spore print, in which a mushroom is placed on a surface and spores are allowed to fall underneath. This technique is often used by mycologists and mushroom hunters to identify the genus or species of a specimen and differentiate between similar-looking taxa.

Frequently asked questions
No, not all fungi are mushrooms. Mushrooms are a type of fungus, but there are many other types of fungi, such as moulds, yeasts, and those that look like coral or stalks.
Some examples of fungi that are not mushrooms include moulds, such as those that grow on bread or fruit; yeasts, which are used in baking and brewing; and coral-like fungi, such as the turkey tail fungus that grows on trees.
Mushrooms typically have a cap and a stem, and they produce microscopic spores on the underside of the cap, similar to how flowers or fruits produce pollen or seeds. The spores can leave a print on paper, known as a spore print. The stem of a mushroom may have a skirt of tissue called an annulus or a sack of tissue at the base called a volva.
No, not all mushrooms are safe to consume. While some mushrooms are edible and even have medicinal properties, others are poisonous and can cause hallucinations or other toxic effects. It is important to properly identify mushrooms before consuming them and seek expert guidance if you are unsure.
