What You'll Learn
Oyster mushrooms have a unique odour
Oyster mushrooms (Pleurotus species) are a versatile and ubiquitous mushroom variety found worldwide. They are known for their unique odour, often described as slightly fishy or seafoody, resembling oysters, hence their name. This distinct aroma is one of the ways foragers identify oyster mushrooms in the wild. While some people associate the smell with anise, others find it reminiscent of borderline rotten fish, particularly when foraged.
The odour of oyster mushrooms is influenced by their growing environment and whether they are wild or cultivated. Wild oyster mushrooms tend to have a stronger smell compared to store-bought or cultivated varieties. Oyster mushrooms are commonly found growing on decaying wood, particularly the wood of cottonwoods, willows, elms, and other hardwoods in riparian and suburban areas. They can also be found on coniferous logs in mountainous regions, although less frequently.
When growing oyster mushrooms, it is normal to notice a heavy mushroomy or "spawny" smell. This aroma indicates the presence of a healthy mushroom culture. However, if the smell turns sweet, sour, or vinegary, it could signal contamination, and the batch may need to be discarded. Proper sterilisation techniques, such as pasteurisation, are crucial to prevent the growth of unwanted microbes and maintain the desired odour profile during cultivation.
In terms of culinary applications, oyster mushrooms are prized for their subtle, briny flavour and tender, smooth texture. They are versatile and can be sautéed, grilled, roasted, or breaded and fried. Oyster mushrooms complement a variety of dishes, including soups, stir-fries, pasta, and more. When storing oyster mushrooms, it is recommended to keep them in the refrigerator, preferably in a paper bag to absorb moisture and maintain freshness.
Overall, the unique odour of oyster mushrooms is an intriguing aspect of these fungi, contributing to their identification, cultivation, and culinary appeal. While their smell may be off-putting to some, it is a distinctive characteristic that sets them apart from other mushroom varieties.

Oyster mushrooms smell like fish
Oyster mushrooms (Pleurotus species) are a ubiquitous variety of mushrooms that can be found growing wild or cultivated worldwide. They are distinguished by their fan or shell-shaped caps with offset stems and white gills. While they typically grow on dead or decaying hardwood trees, they can also be cultivated on various substrates, including wood logs, sawdust, cardboard, and agricultural by-products.
When it comes to their scent, oyster mushrooms have a unique odour that some people describe as slightly fishy or seafoody. This fishy aroma is more commonly associated with wild oyster mushrooms, and it can vary in intensity depending on various factors. Some individuals have reported encountering oyster mushrooms with a super fishy smell, resembling borderline rotten fish. This stronger scent might be influenced by factors such as moisture content or growing conditions.
However, it's important to note that not all oyster mushrooms emit a fishy odour. Cultivated oyster mushrooms, such as those purchased from farmer's markets or stores, typically lack this distinctive smell. The absence of a fishy aroma in cultivated mushrooms could be attributed to controlled growing conditions and selective breeding practices.
The fishy scent in wild oyster mushrooms is one of the ways foragers use to identify them. This smell is often considered a normal part of the mushroom's natural odour profile. However, if you detect any other strong scents, such as a sweet, sour, or vinegary smell, it could indicate a potential issue with the mushrooms, and it may be prudent to discard them.
While the fishy smell of oyster mushrooms might be off-putting to some, it's important to note that cooking them can mitigate this odour. The cooking process seems to neutralise the fishy aroma, resulting in a more pleasant culinary experience.

Oyster mushrooms smell like anise
Oyster mushrooms (Pleurotus ostreatus) are a type of mushroom that is commonly found in lower elevation riparian and suburban areas, growing from trees such as cottonwoods, willows, and elms. They are also sometimes found at higher elevations, although this is less common. Oyster mushrooms are a popular variety, even outside of foraging communities, due to their taste and the ease with which they can be found and cooked.
Oyster mushrooms have a distinctive smell, which some people liken to anise (or licorice). This is thought to be due to the presence of benzaldehyde, a compound used in almond flavouring. Indeed, some people find the smell of oyster mushrooms to be sweet and earthy, rather than reminiscent of anise. However, others disagree with this characterisation, instead reporting that oyster mushrooms have a fishy or seafood-like smell. This may be due to the fact that wild mushrooms tend to have a stronger smell than cultivated mushrooms, and oyster mushrooms bought from a store are almost certainly cultivated.
The noted mycologist Tom Volk describes the smell of oyster mushrooms as "from very mild to very strong, sometimes sweet with the smell of anise (licorice)". However, Michael Kuo, a self-proclaimed mushroom expert, finds the smell peculiar and difficult to describe. Oyster mushrooms are said to have a unique odour, and once you know what they smell like, you will be able to identify them easily.
Oyster mushrooms can be cooked in a variety of ways, including sautéed in butter, breaded and fried, or used in stews or stir-fries. They are known to release a strange smell when fried, but this is not indicative of their flavour, which is widely regarded as pleasant.

Oyster mushrooms smell stronger in the wild
Oyster mushrooms are one of the most common mushroom varieties, found worldwide and thriving in both wild and cultivated settings. They are typically found growing in clusters on decaying wood, and are characterised by their fan or shell shape, and their gills that run down an off-centre stem. Oyster mushrooms have a unique odour, often described as slightly fishy or reminiscent of seafood, and is sometimes compared to anise.
While oyster mushrooms are commonly cultivated and sold in grocery stores, some people also enjoy foraging for them in the wild. Some people have reported that oyster mushrooms they have foraged have a much stronger smell than those bought in stores. For example, one person described the smell of foraged oyster mushrooms as "super fishy", like "borderline almost rotten fish". This was surprising to them as the mushrooms looked nice and were still firm, suggesting they were not past their prime. They speculated that the extra moisture from the rainy day they were picked may have contributed to the stronger smell.
Another person agreed that foraged oyster mushrooms always smell fishy to them, and they use this as one way to identify them in the wild. They also noted that cultivated mushrooms they had bought from the farmer's market did not have this smell. This suggests that wild oyster mushrooms may indeed have a stronger smell than their cultivated counterparts.
It is worth noting that oyster mushrooms can also develop an unpleasant or sour odour when they have gone bad. However, this is typically accompanied by other signs of decay, such as mould or a slimy texture. Therefore, if a foraged oyster mushroom has a strong fishy smell but no other signs of decay, it is likely safe to consume.
In conclusion, while oyster mushrooms are known for their unique odour, wild oyster mushrooms may exhibit a stronger smell than cultivated ones. This could be due to a variety of factors, such as environmental conditions or the stage of maturity at which they are harvested. However, as long as there are no other signs of decay, a strong fishy smell is characteristic of oyster mushrooms and is not cause for concern.

Oyster mushrooms smell when they're bad
Oyster mushrooms are known for their subtle, briny flavour, reminiscent of oysters, and their unique odour. While some people describe the smell of oyster mushrooms as slightly fishy or seafoody, others compare it to anise. However, when oyster mushrooms go bad, they can develop an off, unpleasant, or sour odour, indicating spoilage.
When stored properly in the refrigerator, unopened oyster mushrooms can last for up to 10 days. After opening, they should be consumed within 7 to 10 days. Beyond this timeframe, their texture, taste, and colour may deteriorate, and they may develop an unpleasant smell.
To prevent oyster mushrooms from going bad, it is recommended to store them in a paper bag in the refrigerator, as paper absorbs moisture and helps prevent the mushrooms from becoming slimy. Additionally, it is important to avoid washing the mushrooms before storing them, as the added moisture can cause them to spoil more quickly.
When growing oyster mushrooms, it is normal to notice a heavy mushroomy or spawny smell. However, if the smell turns sweet, sour, or vinegary, it may indicate contamination, and the batch should be discarded. Proper sterilisation of the substrate and growing equipment is crucial to prevent the growth of unwanted fungi and bacteria.
While oyster mushrooms are typically recognised for their unique odour, when they go bad, their smell can become unpleasant and sour, similar to other types of spoiled mushrooms. Therefore, it is important to pay attention to their smell, texture, and appearance to ensure they are safe for consumption.
