Mushroom spores are the reproductive organs of mushrooms. They are similar to seeds, but instead of being contained inside a fruit, they are released into the air as tiny dust-like particles. The purpose of these spores is to spread and find new food sources, but they are also used to create new strains and ensure the survival of the species. The colour of mushroom spores varies, and can be white, cream, black, red, purple, or brown. Spore-producing structures vary from species to species, but some of the most common are gills, pores, or teeth.

Microscopic spores are dust-like particles that travel via wind currents
Mushroom spores are the reproductive organs of the mushroom. They are similar to seeds, but instead of being contained inside an outer coating, they are released into the air as tiny dust-like particles. These particles are microscopic and travel via wind currents.
Mushroom spores are often compared to plant seeds, and their name comes from the Greek word "sporā", which means "seed". However, mushroom spores differ from plant seeds in a few ways. Firstly, plant seeds contain all the genetic material needed to grow a new plant, while mushroom spores only have half the genetic material required to create a new fungus. Two spores from the same type of fungus must meet and fuse to create a new mushroom-producing fungus.
Another difference is that most plant seeds are visible to the human eye, whereas mushroom spores are microscopic and can only be seen with a microscope. To observe the colour of mushroom spores without a microscope, you need to find or create a situation where there are many spores in the same place. This can be done by spotting a natural spore deposit on the mushroom or its surroundings, or by creating a spore print, where the mushroom is left on a piece of paper or other medium overnight.
The microscopic spores produced by mushrooms are so small that it takes 25,000 of them to cover a pinhead. These spores travel from the mushroom along wind currents, and when they land in a moist place, they germinate. Each spore then grows a network of fine threads of hyphae, which release chemicals to dissolve and absorb the nutrients from the surrounding environment, facilitating the growth of the fungus.

Spore colour can vary depending on the thickness of the spore print
Spore prints are the powdery deposits obtained by allowing spores of a fungal fruit body to fall onto a surface underneath. They are an important diagnostic tool for identifying mushrooms. The colour of the spores should be visible when the mushroom is removed. Spore prints are usually white to cream, black, or shades of red, purple, or brown. The colour of the spore print can vary depending on the thickness of the deposit. For example, in the genus Lactarius, thin deposits are usually white, while thick deposits are cream to yellow.
The colour of the spore print is not always a reliable indicator of the mushroom species, as some mushrooms have spores of different colours. For example, the lookalikes Russula crustosa and Russula virescens have yellowish and white spore deposits, respectively. However, historically, the classification of many families of fungi was based on spore colour.
To make a spore print, place the spore-producing surface flat on a sheet of dark and white paper or on a sheet of clear, stiff plastic. This allows for improved contrast and facilitates moving the spore print to a darker or lighter surface. The mushroom is left for several hours, often overnight. Some guides advise using a moisture-resistant enclosure, like a glass or jar, to contain the mushroom during printing.
If you want to study the spores under a microscope, scrape off some of the spores from your spore print with a needle or scalpel, and place them on a microscope slide. Place a drop of water on the spores and cover them with a cover slip. Spore prints can also be preserved on paper or foil by spraying them lightly with an artist spray or hair spray.

Spore prints are made by placing the mushroom on a sheet of paper or plastic
To prevent the spores from being dispersed by air currents, it is recommended to cover the mushroom with a glass bowl or another suitable container. This creates a controlled environment for the spores to fall without interference. The mushroom should be left covered for several hours or even overnight, allowing enough time for the spores to drop and form a distinct print. The exact duration may vary depending on the freshness of the mushroom and the humidity of the environment.
After the designated time has passed, carefully remove the container and lift the mushroom cap to reveal the spore print. It is important to be cautious and gentle to avoid smudging or disturbing the delicate spores. The spore print will display intricate patterns and colours unique to the mushroom species. Once the spore print is created, it can be preserved or stored for future reference.
Creating mushroom spore prints is an educational and enjoyable activity for people of all ages. It provides a practical way to identify mushrooms and learn about their reproductive process. Additionally, the unique patterns and colours of the spore prints can be appreciated as works of art, showcasing the beauty and diversity of the fungal kingdom.

Spore-producing structures vary from species to species, e.g. gills, pores or teeth
Spore-producing structures vary from species to species. Some of the most common structures are gills, pores, and teeth. Gills are found in many well-known gourmet mushrooms, including button, cremini, portobello, oyster, and shiitake. The gills of a mushroom may change colour as it grows and the spores mature, turning from white to a dark purplish brown. The spores can be found on the gills of mature mushrooms and can be scraped off with a knife or tweezers.
Pores are another common spore-producing structure. Examples of popular mushrooms with pores include the sought-after porcini and medicinal mushrooms like reishi and turkey tail. With boletes, the spore colour can provide information that would not otherwise be known about the mushroom, and the colour is usually obtained from the surface of the pores.
Teeth or needles are the most unusual-looking spore-producing structures. Examples of mushrooms with teeth include the shaggy lion's mane and hedgehog mushrooms.
While gills, teeth, and pores are the most common spore-producing structures, some mushrooms produce spores in other ways, including chanterelles, puffballs, and morels. The North American Mycological Association (NAMA) has created a 'how-to guide' for creating spore prints, which can be used to identify mushrooms. Spore prints are made by placing the mushroom on a sheet of paper, foil, or glass, and allowing the spores to drop and form a pattern. The colour of the spores can vary, with shades of white, cream, black, red, purple, or brown being common. However, some mushrooms, like the poisonous false parasol, have green spores.

Mushroom spores are not psychoactive and do not produce psychotropic effects in humans
Mushroom spores are the reproductive units of the mushroom, similar to seeds. They are released into the air as tiny dust-like particles. Spores are not related to mushrooms but are the reproductive parts of a fungus (or mycelium) and contain all the genetic information needed to produce more fungus. They are not capable of producing new plants or psychotropic effects in humans.
Mushroom spores are often confused with psilocybin spores, which are hallucinogenic and can cause psychoactive effects. Psilocybin spores are the tiny, one-celled reproductive units that grow into fleshy, fruiting bodies of psychedelic mushrooms. They are often found on forest floors or rotting logs. However, it is important to note that psilocybin spores do not contain psilocybin, the banned substance in the United States. It is only when the spores germinate and grow into mushrooms that they become illegal.
The misconception that mushroom spores are psychoactive may arise from the fact that mushrooms and spores share a similar shape, with both having a cap and stem. Additionally, the colour of mushroom spores can vary, and historically, the classification of many families of fungi was based on spore colour. However, recent molecular research has shown that fungi with different-coloured spores can sometimes be closely related.
While mushroom spores themselves do not have psychotropic effects, the mushrooms that grow from them can have varying effects on humans. For example, some mushrooms are used as recreational drugs, while others, like psilocybin mushrooms, have shown therapeutic potential in treating conditions such as PTSD and depression. Therefore, it is important to distinguish between mushroom spores, which are not psychoactive, and the mushrooms that grow from them, which may have varying levels of psychotropic effects depending on their species and composition.
