When it comes to cultivating magic mushrooms, various problems may arise that affect the cultivation, resulting in a contaminated mushroom grow kit, impacting both the flavor and quality. Therefore, to avoid potential issues, it is recommended to take special care of certain cultivation factors.
Contaminated mushroom grow kits
When delving into magic mushroom cultivation at home, it’s crucial to learn to identify contamination. This refers to any type of impurity present in the air, soil, or water that can affect the substrates or the mushroom mycelium. Such contaminations can be harmful in the long term as they spread quickly. Therefore, it’s necessary to remove affected crops as soon as possible and isolate them from healthy ones to prevent further spread. However, the specific method to address contamination will vary depending on the type present.
What types of contaminations exist?
Identifying a contaminated mushroom grow kit is usually straightforward, as the mycelium is white, and any other color suggests contamination. However, there are exceptions to consider:
A yellowish hue suggests aging and the formation of new defenses against bacteria.
Blue color in the mycelium can be a sign of bruises.
It’s important to note that contaminating agents thrive in sterilized substrates due to less competition, unlike natural environments where bacteria, fungi, and other microorganisms maintain an ecological balance, avoiding the dominance of contaminants. Some of these contaminating agents include:
- Bacteria: single-celled organisms that reproduce rapidly, which can be combated through pasteurization.
- Fungi: including mold, which grows in filamentous hyphae.
- Pests: tiny insects that not only consume crops but can also transmit diseases.

Some steps to consider when determining if a mushroom crop is contaminated include:
Observing the color of the mycelium
The mycelium is the vegetative tissue of the fungus found in the substrate where it grows. Observing the color of the mycelium can be an effective way to identify contaminated magic mushroom. Normally, healthy mycelium should be white and have a cottony appearance.
However, there are abnormal colors that can indicate contamination. Some examples are:
- Yellow or brown mycelium: may indicate bacterial contamination or the presence of bacterial spots in the cultivation.
- Green mold: the mycelium will be tinged with this color, which can negatively affect the quality of the mushroom cake. This usually occurs due to poor sterilization of environments. To prevent it, disinfectants should be applied, strict sanitation maintained, moisture reduced, and air circulation increased.
- Pink mycelium: a sign of contamination by pink mold, known as Neurospora. This often occurs in agar and grain. It grows through cotton and filter discs, being difficult to eliminate. These crops should be immediately destroyed for thorough cleaning of the area.
- Black mold: appears in grain and agar cultures, called Aspergillus, preferring cultures with a nearly neutral pH and presenting a range of colors from yellow to black. Some of these species are toxic and can be fatal.
Additional tips for visual evaluation of mycelium color
To visually evaluate the mycelium color, it is recommended to follow these tips:
- Observe the mycelium at different growth stages, as its color may vary as the fungus develops.
- Compare with healthy samples, if available, to help identify its condition.
Other ways to detect contamination: unusual smells and textures
Contaminated magic mushrooms can be identified not only by the color of the mycelium but also by unusual smells and textures. Some ways to detect it:
- The presence of bacterial spots on the mushroom cake can produce an unpleasant odor similar to ammonia or chemicals. In the case of bacterial spots, they can be of different colors, such as yellow, brown, or green. Moreover, these spots can change the texture and produce an unpleasant odor.
- Acid rot can generate a sour and unpleasant odor, similar to the smell of vinegar or fermented fruits.
- If a viscous or gelatinous texture appears on the mushroom, this may indicate bacterial contamination, as well as excessive decomposition.
Another type of contamination: dry bubble
In addition to mold, another particular type of contamination that can affect the mushroom is called “dry bubble.” This phenomenon occurs when cultivation conditions are inadequate, such as a high concentration of carbon dioxide or a deficiency of oxygen. Indeed, dry bubble is characterized by small bubbles in the fruiting bodies or in the mycelium, negatively affecting the quality of the cake.

How to prevent contaminated mushroom grow kits?
Prevention is key when it comes to mold control when growing mushroom. Here are some general preventive measures that can be taken:
- Maintain a clean and disinfected environment to reduce the risk of contamination.
- Implement proper personal hygiene practices and in the cultivation area when growing them.
- Control moisture, as mold thrives in humid environments. Maintaining appropriate humidity levels in the cultivation room can help prevent mold growth. Besides, it is recommended to maintain relative humidity between 70% and 85% to avoid mold problems.
- Adequate ventilation is essential to maintain a healthy environment in mushroom cultivation. Proper airflow can help reduce humidity and prevent mold proliferation.
- Regularly inspect for early signs of contamination.
- Preventive isolation, separating affected crops by any suspicion of contamination to prevent its spread.
What to do if contamination is found in mushroom crops?
If contamination is detected, it is crucial to take quick and effective action:
Identify the source and extent of contamination.
- Immediately isolate any affected crops to prevent further deterioration.
- Properly dispose of contaminated crops following recommended guidelines.
- Once disposed of, disinfect all surfaces, equipment, and cultivation tools.
- Establish a regular deep cleaning program and investigate the cause of contamination to prevent future cases. Further, it may be necessary to review your cultivation practices or analyze possible problems in the environment where mushrooms are grown.
To determine if a mushroom cake is contaminated, early identification and prompt action to maintain quality are essential.
