Mushrooms are fungi that come in a variety of shapes, sizes, and smells. Some mushrooms have a pleasant earthy fragrance, while others have a strong, unpleasant odour. Mushrooms are primarily composed of water and require air to survive and thrive before being cooked. They should be dry, firm, and smooth when fresh, and have a long shelf life if stored properly. The smell of mushrooms can be an indicator of their edibility, with strong or sour-smelling mushrooms being unsafe for consumption. Mushrooms are known to have distinct odours, with some having a farinaceous odour reminiscent of cucumber or watermelon rind, while others, like the Stink Horn Mushroom, have a foul odour.
| Characteristics | Values |
|---|---|
| Smell | Mushrooms are supposed to have a faint earthy smell. However, different types of mushrooms have different smells, ranging from farinaceous (like cucumber or watermelon rind) to spermatic (like human semen). |
| Freshness | Fresh mushrooms are dry, firm, and smooth to the touch. They should not be sticky, slimy, shriveled, or moldy. |

Fresh mushrooms should smell earthy, while bad mushrooms smell sour or rancid
Mushrooms are known to have distinct odours, and their smell can indicate whether they are fresh or bad. Fresh mushrooms should have a pleasant, earthy smell. Mushrooms that are fresh are also dry, firm, and smooth. They should not be sticky, slimy, or shrivelled.
Some mushrooms are known for their particularly strong scents. For example, the Tricholoma dulciolens has a strong, unique odour that is hard to describe but is memorable. The mushroom known as Clitopilus prunulus has a farinaceous odour, which is similar to fresh meal or raw pastry, or even cucumber or watermelon rind. The Inocybe species has an embarrassing smell, described as spermatic, as it resembles the odour of human semen.
Some mushrooms have more pleasant scents. For example, the Lactarius hibbardae, a North American mushroom, has a distinct and pleasant odour of coconut. The Cortinarius traganus smells like dried apples or pears, while the Cortinarius violaceus and C. hyrcinicus have a notable odour of cedarwood.
However, bad mushrooms will smell sour or rancid and may be unsafe for consumption. They may also be softer, sticky, slimy, shrivelled, mouldy, and discoloured. To prevent mushrooms from going bad, it is best to store them in a paper bag in the refrigerator to allow for air circulation and prevent the development of mould and slime.

Mushrooms of the species Clitopilus prunulus have a farinaceous odour, likened to cucumber or watermelon rind
Mushrooms are supposed to have a pleasant earthy smell when they are fresh. However, different species of mushrooms have different odours. Mushrooms of the species Clitopilus prunulus, also known as the Sweetbread Mushroom or The Miller, have a farinaceous odour. Farinaceous, by definition, refers to the odour of fresh meal or raw pastry. However, many people liken this odour to cucumber or watermelon rind. Some people find this odour disagreeable, but it disappears upon cooking, leaving a pleasant mushroom flavour.
The intensity of a mushroom's odour can vary depending on whether it is fresh or dried. For example, the odour of the Inocybe mushroom is more subtle when fresh but intensifies upon drying. Similarly, the mushroom Pholiota squarrosoides grows in large clusters and has an odour reminiscent of coffee and chocolate. However, this scent is not present in the cut flesh.
The odour of mushrooms can also be used to distinguish between similar-looking species. For instance, Cortinarius camphoratus and C. traganus look alike, but C. camphoratus has an unpleasant odour of rotten potatoes. Additionally, Cortinarius violaceus and C. hyrcinicus have a notable cedar wood scent that distinguishes them from other mushrooms.
The sense of smell can be crucial in identifying mushrooms, and some odours are quite distinctive. For example, Lactarius hibbardae has a distinct and pleasant coconut scent, while Inocybe lacera has an embarrassing odour that is often the subject of jokes.
Overall, while mushrooms are supposed to have a pleasant earthy smell, the odour can vary depending on the species, and some people may find certain odours more disagreeable than others. In the case of Clitopilus prunulus, the farinaceous odour is likened to cucumber or watermelon rind and is one of the characteristics that sets it apart from other mushrooms.

Some mushrooms smell like rotten potatoes, while others smell like cedar wood
Mushrooms are supposed to have a pleasant, earthy scent when fresh. However, different species of mushrooms have different smells, with some having distinct odours that are less pleasant. Some mushrooms, such as the Cortinarius camphoratus, are known for their unpleasant odour of rotten potatoes. Mycologists have reported being able to smell this mushroom from a distance of nearly 100 meters. The mushroom's smell is so strong that it can be used to locate its fruiting bodies.
On the other hand, some mushrooms have a more pleasant aroma, such as the Cortinarius violaceus, which has a notable odour of cedar wood. This mushroom is also known for its unusual colour and cystidia. The flesh of the Cortinarius violaceus has a mild taste and a pleasant smell, described as reminiscent of cedar wood. Cedar wood itself is known for its rich and warm fragrance, often associated with luxury and natural freshness. The scent of cedar wood is due to the presence of volatile organic compounds (VOCs), specifically lignin and terpenes, which contribute to its aromatic qualities.
The smell of mushrooms can vary depending on their freshness and storage conditions. Fresh mushrooms are typically dry, firm, and smooth, with a pleasant earthy aroma. However, if mushrooms start to spoil, they may develop an unpleasant smell, indicating that they are no longer safe to eat. Bad mushrooms may also exhibit physical signs of deterioration, such as a slimy texture, discolouration, and the presence of mould.
The scent of mushrooms is an important factor in their identification and edibility. While some mushrooms with strong odours may be inedible or toxic, others with pleasant aromas may be safe for consumption. It is crucial to properly identify mushrooms before consuming them, as some species closely resemble toxic varieties. Additionally, proper storage practices, such as avoiding excess moisture and storing them in paper bags, can help prolong the freshness and pleasant smell of mushrooms.

Stinkhorn mushrooms, or Phallus Impudicus, are known for their foul odour
The stinkhorn mushroom has a distinctive appearance, often described as phallus-shaped, giving rise to its scientific name, which translates to "shameless penis". It emerges from an egg-shaped base with a pitted, bell-shaped cap covered in olive-brown slime. The immature stinkhorn is whitish or pinkish, while the mature stinkhorn is taller, with a greenish-brown slimy gleba. The mushroom's growth rate has been measured at an impressive 10-15 cm per hour.
The stinkhorn mushroom has been given various names throughout history, reflecting its unique appearance. The Italian naturalist Ulisse Aldrovandi called it "fungus priapeus" in 1560, while John Gerard referred to it as the "pricke mushroom" in 1597. John Parkinson named it the "Hollanders workingtoole" in 1640, and Linnaeus, who described the species in 1753, gave it its current binomial name, translating to "immodest phallus".
The stinkhorn mushroom is commonly found in woods and gardens, often appearing in spring and summer during cool, wet weather. It is associated with rotting wood and leaf mulch environments. The spores of the stinkhorn are contained within the slime that covers its cap, and the mushroom's foul odour is an important mechanism for attracting insects to aid in spore dispersal.
While the stinkhorn mushroom is not considered toxic, there is a historical account from 1854 of a person experiencing negative effects after consuming it. The person suffered from stomach tension, convulsions, loss of speech, and a stupor lasting 48 hours. However, no major toxicity is expected, and supportive care would likely be sufficient in such cases.

Mushrooms should be stored in paper bags to prevent the development of a slimy texture and bad smell
Mushrooms have a distinctive smell, and while fresh mushrooms have a pleasant earthy scent, bad mushrooms may smell unpleasant. Mushrooms are highly perishable, and storing them correctly is essential to prevent the development of a slimy texture and bad smell.
Mushrooms are composed mainly of water, and they need air to survive and thrive before being cooked. The goal of mushroom storage is to prevent them from releasing water and pulling moisture from the air. Plastic containers or bags can trap moisture, leading to a damp environment that degrades the quality of the mushrooms very quickly. Therefore, it is best to avoid storing mushrooms in plastic containers or bags, especially those without holes.
Paper bags are ideal for storing mushrooms because they strike a perfect balance between air circulation and moisture absorption. They allow the mushrooms to breathe, preventing the buildup of moisture that can lead to slime formation and unpleasant odours. The paper bag absorbs any excess moisture, keeping it from settling on the mushrooms' surface and causing spoilage.
To store mushrooms in a paper bag, simply place whole, unwashed mushrooms in a brown paper bag and fold the top over to seal. It is also recommended to use a paper towel to wrap the mushrooms before placing them in the bag. The paper towel will absorb any excess moisture, further reducing the risk of slime development.
By following these storage guidelines, you can help maintain the freshness and extend the shelf life of your mushrooms, preventing the development of a slimy texture and bad smell.
