Brown mushrooms are a type of fungus that grows and spreads in dark areas, such as overhangs, caves, or even under trees. They are also found on fallen trees in the Minecraft world. In the game, brown mushrooms can be used in several recipes and can be found as drops from zombies or in various locales across the island. In real life, brown mushrooms are edible and are known as penny buns. They are prone to rapid browning due to a chemical interaction between atmospheric oxygen and their natural enzymes. To prevent this, they should be stored in the refrigerator and kept dry.

What You'll Learn

Store in the fridge to slow browning
Mushrooms are a versatile ingredient, lending a meaty texture and flavour-enhancing savoury compounds to a variety of dishes. However, they are notoriously short-lived and prone to rapid browning. This browning is caused by an enzymatic reaction when the mushroom's cells are damaged or bruised, triggered by the release of an enzyme called polyphenol oxidase (PPO). When exposed to oxygen, PPO catalyses a reaction that forms brown pigments.
To slow down the browning process, it is recommended to store mushrooms in the refrigerator at a consistent temperature below 40°F (4°C). This slows down the enzymatic reaction that causes browning. It is also important to handle mushrooms gently and avoid bruising or damaging them during storage.
One effective method for storing mushrooms in the fridge is to use a paper bag or a breathable container, such as a mesh bag or a container with holes. This allows for airflow and helps maintain a consistent humidity level, which is crucial for slowing down the browning reaction. The paper bag should be placed in the refrigerator, ensuring a constant cool temperature. It is also recommended to avoid washing or wiping mushrooms before storing them, as this can speed up the browning process by removing their protective membrane.
To further extend the shelf life of mushrooms and slow down browning, it is suggested to use a paper towel or a cloth inside the container to absorb excess moisture and maintain a dry environment. Additionally, lemon juice or vinegar can be used sparingly to prevent browning. The acidity in these substances inhibits the activity of the PPO enzyme, slowing down the browning reaction. However, excessive acidity can affect the mushroom's texture and flavour, so moderation is key.

Keep mushrooms dry
Keeping mushrooms dry is essential to prevent spoilage and extend their usable life. Here are some detailed tips to achieve this:
Firstly, understand that mushrooms are highly perishable and prone to rapid browning due to a chemical interaction between oxygen and their natural enzymes. This process is accelerated by physical damage, which ruptures their internal cell walls and exposes them to air. Therefore, handle mushrooms gently and avoid washing or wiping them before cooking, as this removes their protective membrane.
When purchasing mushrooms, choose fresh, flawless specimens without bruises or blemishes. Loose mushrooms are best stored in a brown paper bag, which allows them to breathe. Avoid placing heavy or rigid items in the bag, and ensure they are not crushed or damaged by other products. You can also over-wrap the paper bag with a plastic bag to further prevent drying. Alternatively, buy mushrooms packaged in shrink-wrap, as they are protected by a moisture-regulating tray.
If you are drying mushrooms for long-term storage, there are several effective methods to remove moisture. Air drying is the cheapest and easiest option. You can also use a dehydrator or oven set to a low temperature, around 40°C to 60°C, for 4 to 8 hours or until they snap under pressure. Remember to pre-dry your mushrooms by spreading them evenly on drying racks or trays, ensuring good air circulation.
Another method involves using a desiccant, a solid substance that absorbs water. Prepare a container with a layer of desiccant, covered with paper towels, and bend a metal mesh to create a platform for the mushrooms. Place the mushrooms on the mesh, ensuring they do not touch the desiccant. Cover the container with an airtight lid, and the desiccant will absorb moisture from the mushrooms. Check the mushrooms every few days until they are dry.

Use a paper bag
Storing brown mushrooms in a paper bag is a great way to keep them fresh for longer. Mushrooms are delicate and perishable, and improper storage can lead to rapid spoilage and even poisoning.
Firstly, it is important to note that mushrooms should not be stored in plastic bags. Plastic traps moisture, creating a damp environment that causes discoloration, mould, and slime. It also prevents mushrooms from breathing, leading to rapid bacterial growth.
Paper bags, on the other hand, offer the ideal balance of air circulation and moisture absorption. They allow mushrooms to breathe and slowly dry out, rather than trapping moisture. To store mushrooms in a paper bag, simply place whole, unwashed mushrooms into a small paper bag and fold or roll the top down to seal it. It is best to use a paper bag with a paper towel lining, as the paper towel will absorb moisture, helping to keep the mushrooms fresh for even longer.
Mushrooms stored in paper bags can last for 5-10 days, depending on the species and their condition. It is recommended to use them within a week for peak freshness and flavour. If you notice any slimy mushrooms, discard them, as this indicates spoilage. Dark spots on the mushrooms are also a sign of decline, and while they are still safe to eat, it means they should be consumed soon.

Avoid physical damage
To avoid physical damage to mushrooms, it is important to handle them with care and avoid bruising or cutting them excessively. If you need to cut or slice mushrooms, do so just before using them to minimize exposure to oxygen and prevent browning. When storing mushrooms, avoid placing them in plastic wrap or containers that will trap moisture, as this can lead to mold and spoilage. Instead, transfer them to a paper bag or a breathable container to maintain humidity and prevent moisture buildup.
When purchasing mushrooms, opt for loose mushrooms over pre-packaged containers to carefully inspect their quality and avoid physical damage during transport. Choose fresh, flawless specimens without visible blemishes and place them gently in your bag. Avoid washing or wiping mushrooms before storing them, as this can remove their protective membrane and accelerate the browning process.
To further extend the shelf life of mushrooms, store them in the refrigerator, as low temperatures slow down the oxidative reaction that causes browning. You can also dip the mushrooms briefly in water containing lemon juice, citric acid, or ascorbic acid (vitamin C) to keep them fresh and prevent browning. Additionally, freezing or dehydrating mushrooms can effectively prolong their shelf life by slowing down decomposition and inhibiting microbial growth.
It is worth noting that physical damage to mushrooms can accelerate browning due to enzymatic reactions. This occurs when the cell walls are damaged, releasing enzymes that react with oxygen and cause the formation of brown pigments. While brown mushrooms may still be safe to eat depending on the cause of discoloration, always inspect them carefully before consumption and cook thoroughly to break down any potential toxins.

Find them in Minecraft's dark forests
Brown mushrooms are a type of fungus that grows and spreads in dark areas in Minecraft. They can be found in Minecraft's dark forests, specifically under trees, and in other shaded areas such as dark caves or ravines. They also tend to appear in the Nether, which is well-lit, but they are more commonly found in darker locations.
To find brown mushrooms in Minecraft's dark forests, follow these steps:
- Look for dark oak forests or swamps: These biomes are known to have a higher chance of generating brown mushrooms. You can use online tools to create a map of your world's biomes and locate these areas more easily.
- Search under trees: Brown mushrooms are commonly found under the trees in dark forests. Look for large trees such as oak, birch, spruce, or jungle trees, as these have a higher chance of generating mushrooms.
- Explore poorly lit areas: Brown mushrooms naturally generate in areas with a light level of 12 or less. Focus your search on shaded parts of the forest, as they are more likely to spawn mushrooms.
- Cut down large mushrooms: In dark forests, you may find huge mushrooms that can be mined for smaller mushrooms. Cutting down these large mushrooms can yield up to 2 smaller mushrooms of the same color.
- Cultivate your own: If you find a brown mushroom, you can place it in a dark area and it will spread over time. You can also use bone meal on a brown mushroom in a dark area to grow a giant mushroom, which can then be mined for more mushrooms.
Remember that brown mushrooms in Minecraft are based on the edible Boletus edulis, also known as penny buns. They are a valuable resource for crafting and trading, and can be bought from wandering traders or found in witch huts and woodland mansions.
