Microscopes: use 1000x magnification to see details invisible to the naked eye
To study mushroom spores, microscopy – the use of a microscope to examine objects invisible to the naked eye – is essential. A microscope with 1000x magnification and an oil immersion lens is recommended to examine mushrooms and their spores. The microscope should also have a fine-focus knob, a movable stage, and an electric light source.
To calibrate the microscope, a special slide called a stage micrometer is required. The units in the microscope's eyepiece measuring system are compared to the predetermined units on the stage micrometer to establish a conversion basis. This conversion basis will then be applied each time a measurement is made, unless the conversion is 1:1.
To create slides of spores, place the mushroom cap underside down on a microscope slide and cover it to prevent drafts from blowing the spores away. Leave it for an hour or two, or even overnight, for the spores to drop onto the slide. Then, place the slide on the microscope stage and examine the spores, starting at low power before increasing to high power to see individual shapes.
At low power, the spores will appear as streaks of tiny specks. At higher powers, the individual shapes of the spores can be observed. To measure the spores, use the ruler in the eyepiece, remembering to convert the values to microns using the established conversion basis. Take multiple measurements (around 10 to 20) to get a general understanding of the spore size.
In addition to spore size, other microscopic features such as spore colour, shape, attachment, and reaction to chemical tests are important for identifying mushrooms. For example, Melzer's reagent can be used to determine if spores are amyloid, inamyloid, or dextrinoid, which is essential for identification.

Mushroom types: B+ spores are good for beginners, while White Teacher spores are for experts
Studying mushroom spores under a microscope can be a fascinating hobby. To get started, you'll need a microscope with a magnification of at least 1000x. You can often find used microscopes online, many of which will have belonged to schools or research institutions.
When it comes to mushroom types, B+ spores are a popular choice for beginners. They are versatile, adaptable, and relatively easy to study. B+ spores can thrive in a wide range of temperatures and can be found in the wild. Their resilience and adaptability make them a favourite among novice mycologists. B+ mushrooms are also known for their large size and caramel-coloured caps.
On the other hand, White Teacher spores are more suitable for experts. They are a hybrid strain that comes from the Golden Teacher Mushroom Spores and the Albino Penis Envy strains. Their spores are more translucent, requiring a practised eye to study them. White Teacher spores are visually stunning, with a beautiful cream-white colouring. They are also consistent, plentiful, and simple to work with. However, they are very rare and exclusively available on certain websites.
Other mushroom spores that are suitable for beginners include Golden Teacher spores, known for their robust growth and unique golden caps, as well as Mexican Dutch King spores, which thrive in various conditions and exhibit strong growth patterns. For more advanced growers, the Penis Envy (PE) strain is a favourite due to its interesting name and shape, as well as its beautiful microstructures.
When purchasing mushroom spores, ensure that they are sold for research or educational purposes to guarantee quality and variety. Mushroom spores are typically sold as syringes or spore prints. Syringes contain spores suspended in distilled water and should be sterilised to prevent contamination. Spore prints, on the other hand, have dried spores that need to be hydrated and extracted onto microscope slides.

Spore colours: colours can be identified by treating with KOH
Studying mushroom spores can be a fascinating hobby. It is one of the easiest and most enjoyable science hobbies that anyone can take up. If you are just getting started, the first thing you will need is a microscope. A microscope with 1000x magnification is a great start. You can find a used microscope by searching online auction sites in your area. You can also buy mushroom spore syringes that offer microscopy kits, so you will receive your syringes plus glass slides, protective cases, and instructions on how to view the spores under your microscope.
Once you have your equipment, you can begin studying mushroom spores. One way to study mushroom spores is to look at their colour. Spore colours can be identified by treating them with certain chemicals, such as potassium hydroxide (KOH). A 3-10% solution of KOH gives a colour change in some species of mushrooms. For example, in Agaricus, some species such as A. xanthodermus turn yellow with KOH, many have no reaction, and A. bbrutilescens turns green. Distinctive changes occur for some species of Cortinarius and Boletes.
It is important to note that chemical tests are not always reliable for identifying mushroom spores. Most mushroom species possess similar compounds, with only minute changes between them. Additionally, some mycologists disagree on the validity of chemical tests, with some arguing that tests must be performed on fresh mushrooms to be valid. Therefore, it is essential to use multiple methods to identify mushroom spores, such as microscopy, in addition to chemical tests.
When working with mushroom spores, it is crucial to prioritize safety. Some mushroom spores are legal to purchase for educational purposes only, and they may become illegal when germinated. Additionally, mushroom spore syringes must be sterilized to prevent contamination by mould or bacteria. By following safety guidelines and using multiple identification methods, you can accurately and safely study mushroom spores and their colours using KOH treatment.

Spore shapes: the shape of cystidia can help differentiate between species
Studying mushroom spores can be a fascinating hobby for anyone interested in mycology. To begin studying mushroom spores, one must first understand the anatomy of a mushroom. The standard for the name "mushroom" is the cultivated white button mushroom, Agaricus bisporus, which has a stem (stipe), a cap (pileus), and gills (lamellae) on the underside of the cap. The gills are covered by a layer of microscopic spore-bearing cells called the hymenium, which produces spores to help the fungus spread.
Now, let's focus on the role of cystidia in species differentiation. A cystidium (plural: cystidia) is a relatively large cell found on the sporocarp of a basidiomycete, often on the surface of a mushroom gill between clusters of basidia. Cystidia have unique and highly variable shapes that are often specific to a particular species or genus. This makes them an invaluable tool for identifying different species of mushrooms.
The shape of cystidia can vary depending on their location within the mushroom structure. For instance, cheilocystidia are found on the edge of a lamella (gill), while pleurocystidia are found on the face of the lamella. Circumcystidia occur on the margin of the cap, and dermatocystidia or pileocystidia are found on the surface of the cap. Additionally, caulocystidia are present on the stipe, and gloeocystidia exhibit an oily or granular appearance under the microscope.
By examining the distinct shapes and locations of cystidia, mycologists can accurately identify and classify different species of mushrooms. This micromorphological characteristic is especially useful when combined with other identifying features such as spore shape, size, colour, attachment, ornamentation, and reaction to chemical tests. Therefore, the shape of cystidia plays a crucial role in differentiating between mushroom species, contributing to our understanding of the diverse world of fungi.
