Knowing when to harvest mushrooms is a crucial step in the cultivation process. The right time to harvest is when the mushroom is mature and has distributed most of its spores. The specific timing varies depending on the type of mushroom, but generally, it is when the veil connecting the cap to the stem is about to break. For Oyster mushrooms, this occurs three to five days after the first mushrooms begin to form. For Psilocybe cubensis, the most popular and easiest type of magic mushroom to grow, you have just a few days after the pinning process to harvest. For other types of mushrooms, it is important to observe the veil of each mushroom and harvest when it is still lightly coloured and before it darkens and starts to sag.

What You'll Learn
Fresh mushrooms should be dry, plump, and firm
When it comes to determining whether your mushrooms are ripe and ready to eat, it's important to look for certain characteristics that indicate freshness and quality. Fresh mushrooms should exhibit the following key attributes: dry, plump, and firm.
Starting with dryness, fresh mushrooms should not feel wet or slimy to the touch. The surface of the mushroom cap and stem should be relatively dry, with a matte or slightly shiny appearance. Any excess moisture can be an indication of deterioration or improper storage. It is important to distinguish between the natural moisture content of the mushroom and excessive wetness.
Secondly, plumpness is an important indicator of freshness. Ripe mushrooms should appear plump and meaty, with a full shape. The caps should be rounded and slightly curved inwards. Avoid mushrooms that look shrivelled, shrunken, or significantly wrinkled, as this indicates dehydration and a potential loss of freshness.
In addition, firmness is a key characteristic of ripe mushrooms. Fresh mushrooms should feel firm to the touch, with a slight give when pressed gently. The texture should be resilient and spring back after being touched or squeezed gently. Avoid mushrooms that feel overly soft, mushy, or spongy, as this can indicate over-ripeness or spoilage.
When examining the mushrooms, it's important to inspect both the caps and the stems. The caps should be closed or slightly open, with gills that are not fully exposed. The gills underneath the cap should be a light colour, ranging from pale tan to pale brown. Avoid mushrooms with discoloured gills or those that appear slimy.
Additionally, the stems of fresh mushrooms should be intact and relatively dry. Avoid stems that are slimy, brittle, or severely discoloured. It's normal for the ends of the stems to be slightly drier and lighter in colour, but excessive dryness or discolouration may indicate that the mushrooms are past their prime.

Bad mushrooms are slimy, smelly, and mouldy
Fresh mushrooms are dry, firm, and smooth, with a pleasant earthy smell. Bad mushrooms, on the other hand, are slimy, smelly, and mouldy.
Slime is a clear sign of spoilage, occurring when mushrooms have been stored incorrectly or have been in the fridge for too long. If the slime is the only sign of deterioration, the mushrooms can still be salvaged by cooking them in soups, sauces, or chillies. However, if there are other signs of decomposition, such as an unpleasant odour, the mushrooms should be avoided as they can make you sick due to bacteria formation.
Discolouration is another indicator of spoilage. If your mushrooms are developing dark spots or a darker hue, they are going bad and should not be consumed. Mushrooms should be dry, and when they start to dry out and become wrinkled or shrivelled, it's another sign that they are past their prime.
To prolong the shelf life of mushrooms, proper storage is key. It is recommended to store mushrooms in a way that allows them some air without drying them out. Keeping them in a paper bag with the top loosely rolled up inside the refrigerator is a popular method to maintain freshness. Alternatively, storing them in plastic bags lined with paper towels helps capture moisture, but the towels should be changed regularly.
In summary, bad mushrooms are characterised by sliminess, discolouration, wrinkles, and an unpleasant odour. To prevent spoilage, proper storage methods such as using paper bags or plastic bags with paper towels, are essential.

Store mushrooms in paper bags in the fridge
Mushrooms are a versatile ingredient that can add a meaty texture and umami flavour to a variety of dishes. However, they have a short shelf life and require proper storage to prevent spoilage. One effective way to store mushrooms and maintain their freshness is to use paper bags.
When storing mushrooms, it is important to let them breathe by providing some air circulation while also preventing excess moisture buildup. Plastic bags can trap moisture, creating a damp environment that accelerates the degradation of mushrooms. In contrast, paper bags offer the ideal balance of air circulation and moisture absorption. By absorbing excess moisture, paper bags help to preserve the delicate texture and taste of mushrooms.
To store mushrooms in a paper bag, simply place whole, unwashed mushrooms in a brown paper bag and loosely fold over the top to seal it. This allows for proper air circulation while also absorbing any excess moisture. The cool temperature of the refrigerator will maintain the crispness of the mushrooms and extend their shelf life. It is recommended to use the mushrooms within a week for peak freshness and flavour.
It is also important to note that mushrooms should be stored away from strong-smelling food, as they can absorb those odours. Additionally, if you have already sliced the mushrooms, it is best to store them in an airtight container in the refrigerator.
By following these simple steps and storing mushrooms in paper bags in the fridge, you can prolong their freshness and enhance their flavour, making them a delightful addition to your culinary creations.

Bad mushrooms can make you sick
When it comes to mushroom foraging or even store-bought mushrooms, one of the most important things to remember is that bad mushrooms can indeed make you sick. Mushroom poisoning is a serious matter and can have severe consequences if not addressed promptly and properly. It is crucial to be able to identify the signs of spoilage and know what to do if you accidentally consume contaminated mushrooms.
Mushrooms are a type of fungus, and like all fungi, they can spoil and become contaminated with bacteria or molds. While most mushroom varieties are safe to eat when fresh and properly cooked, they can quickly deteriorate and become unsafe. Bad mushrooms may look discolored, slimy, or dry and brittle. They may also have an off-odor or a bitter taste. In some cases, mushrooms can be contaminated with harmful bacteria, such as E. coli or Salmonella, which can cause food poisoning.
The symptoms of mushroom poisoning can vary depending on the type of toxin involved. Some common symptoms include stomach pain, nausea, vomiting, diarrhea, and cramping. In more severe cases, mushroom poisoning can lead to hallucinations, delirium, and even death. It is important to seek medical attention immediately if you experience any of these symptoms after consuming mushrooms.
To avoid mushroom poisoning, it is crucial to properly store and cook mushrooms. Fresh mushrooms should be refrigerated and consumed within a few days of purchase. Before cooking, inspect the mushrooms for any signs of spoilage and trim away any discolored or slimy parts. Cooking mushrooms properly also helps to reduce the risk of food poisoning. Mushrooms should be cooked thoroughly until they are soft and tender.
If you suspect that you have consumed bad mushrooms, it is important to act quickly. Induce vomiting or, if available, use activated charcoal to help absorb the toxins. Seek medical attention immediately, even if you are feeling mild symptoms. Bring a sample of the mushroom you consumed so that it can be identified and proper treatment can be provided.
By being vigilant and informed about mushroom safety, you can greatly reduce the risk of mushroom poisoning. Always purchase mushrooms from reputable sources, store them properly, and inspect them before consumption. When in doubt, it is always better to err on the side of caution and discard any mushrooms that appear suspicious. Your health and well-being are paramount, so stay informed and stay safe when it comes to mushroom consumption.

Mushrooms last 4-10 days in the fridge
Mushrooms are a versatile and nutritious food, adding flavour and texture to many dishes. Knowing how to store them properly is key to ensuring their freshness and longevity. While they may not have a long shelf life compared to other produce, mushrooms can last for up to 10 days when stored correctly in the fridge. After purchasing or picking mushrooms, it is essential to inspect them for any signs of damage or spoilage. Remove any mushrooms that show signs of deterioration, as one rotten mushroom can quickly spread mould to the others. Then, gently wipe the mushrooms with a damp paper towel to clean them. It is important to not wash the mushrooms until just before cooking, as moisture can accelerate spoilage.
Once cleaned, place the mushrooms in a paper bag, a glass bowl, or a container with a paper towel at the bottom. The paper bag method works well as it allows the mushrooms to breathe and prevents moisture buildup. If using a glass bowl or container, be sure to cover them with a paper towel or a loose-fitting lid. Then, store the mushrooms in the fridge, ideally in the main body rather than the door, where the temperature is more consistent.
Check the mushrooms regularly to ensure they remain firm and odour-free. Depending on the variety, stored this way, mushrooms should last for about a week to 10 days. It is important to note that some mushrooms may last longer, especially if they are drier varieties such as porcini or shiitake. However, if they are stored in a humid environment, they are more likely to spoil within four to seven days. Therefore, it is crucial to monitor their condition and use them within the specified timeframe.
Additionally, it is worth mentioning that this storage method applies to common button mushrooms and most specialty mushrooms. However, for wild mushrooms, such as morels or chanterelles, slightly different storage techniques may be required. These varieties are often more delicate and require extra care. Overall, by following these simple steps, you can ensure that your mushrooms stay fresh and tasty for up to 10 days, ready to be incorporated into your favourite recipes.
