Identifying mushrooms can be a challenging task, and it is important to be cautious as edible and poisonous mushrooms often look alike. While some sources recommend leaving mushroom identification to professional mycologists, there are certain characteristics that can help identify mushrooms, such as the colour of the gills, the shape and colour of the cap, and the presence of scales or rings on the stem. Additionally, the substrate, or the material the mushroom is growing from, can provide clues about its identity. It is always recommended to seek expert advice or refer to reliable guidebooks for accurate mushroom identification.

What You'll Learn
- Examine the gills: false gills, no gills, or gills that are white, tan, brown, purple, or green can indicate different mushrooms
- Observe the cap: smooth, funnel-shaped, convex, or bell-shaped caps in colours like yellow, grey, black, brown, or white can help distinguish species
- Check the stem: fibrous, smooth, or tough stems that are long, thin, or stout with or without a ring can be indicative of certain mushrooms
- Smell and taste: some mushrooms have a slightly fruity or flowery smell and a great taste
- Habitat: mushrooms grow in different habitats, like on the ground, at the edge of a trail, or in grasslands, meadows, and wooded areas
Examine the gills: false gills, no gills, or gills that are white, tan, brown, purple, or green can indicate different mushrooms
When identifying mushrooms, it is important to examine the gills. Gills are the thin, papery structures that hang vertically under the cap of the mushroom. They produce spores, which are dispersed by the millions and scattered by wind currents.
Some mushrooms have false gills, which are wrinkled folds that resemble gills. False gills can be found on the chanterelle and funnel chanterelle mushrooms. These mushrooms have ridges that are folded in a gill-like manner.
Some mushrooms do not have gills at all. For example, the Old Man of the Woods mushroom has no gills, while the underside of the cap of the hedgehog mushroom is full of spines.
The colour of the gills can vary and is an important feature when identifying mushrooms. Mushrooms with white gills should be avoided as they can be poisonous. Edible mushrooms typically have brown or tan gills. Mushrooms in the Pleurotus genus, often called "oyster mushrooms," have gills that are white or creamy. Mushrooms in the Kuehneromyces genus have gills that are brown or tan. Mushrooms in the Stropharia genus have gills that turn dark as they mature due to spore production.
The way in which the gills attach to the stem is also important when identifying mushrooms. They may be "decurrent," meaning they run down the stem, "free," meaning they are not attached to the stem, or attached directly or by a notch.

Observe the cap: smooth, funnel-shaped, convex, or bell-shaped caps in colours like yellow, grey, black, brown, or white can help distinguish species
The cap of a mushroom, also known as the pileus, is one of the most recognisable parts of a mushroom. It comes in various shapes, sizes, colours, and textures, which can aid in identification. Caps can be smooth or covered with scales or teeth. The shape of the cap can help identify the species or at least narrow down the possibilities. For example, a convex cap shape is commonly observed, resembling a gentle curve or a bowl. In contrast, a cuspidate cap looks like a witch's hat.
Some other common cap shapes include bell-shaped, conical, flat, and round. Bell-shaped caps are often seen in younger mushrooms and can evolve as the mushroom matures. Conical caps are shaped like cones, and some species retain this shape throughout their lives. Flat caps indicate a mature mushroom, as many species' caps flatten with age. Round caps are typically found in puffballs and other non-gilled mushrooms.
Additionally, the physical characteristics of the cap, such as colour and texture, are also important for identification. For example, the caps of some mushrooms are smooth, funnel-shaped, convex, or bell-shaped and are coloured yellow, grey, black, brown, or white. These characteristics can help distinguish different species of mushrooms.
It is important to note that mushroom identification can be challenging and potentially dangerous. Observing the shape and colour of the cap is just one aspect of identifying mushrooms. Other factors to consider include the habitat, gills, spores, and stem features. It is crucial to use multiple sources of information and not just rely on visual identification when identifying mushrooms, especially when it comes to wild mushrooms.
Mushrooms: How Long Do They Last?

Check the stem: fibrous, smooth, or tough stems that are long, thin, or stout with or without a ring can be indicative of certain mushrooms
When identifying mushrooms, it is important to pay attention to the characteristics of their stems. The stems of mushrooms can vary in terms of texture, length, thickness, and the presence or absence of a ring.
Some mushrooms have fibrous stems, such as those in the Melanoleuca genus, which are commonly found in grasslands, meadows, and wooded areas. These fibrous stems can also be smooth or slightly fibrous, and they are usually long and thin.
On the other hand, some mushrooms have tough stems. For example, the Hypholoma genus has reddish-brown caps and curved stems that are often tough and slender.
The presence or absence of a ring on the stem is another important characteristic. Many mushrooms, such as those in the Pleurotus genus, do not have a ring or partial veil. These mushrooms are commonly known as "oyster mushrooms" due to their broad, fan-shaped, or oyster-shaped caps. In contrast, the Stropharia genus is known for having a distinctive annulus (ring) on their stems.
Additionally, the length and thickness of the stem can vary. For example, the Pleurotus genus has stems that are either lateral or almost absent, while the Stropharia genus has slender stems.
It is important to note that mushroom identification can be complex, and it is crucial to be cautious when identifying mushrooms for consumption. It is always recommended to seek guidance from reliable sources or experts in mycology, the scientific study of fungi.

Smell and taste: some mushrooms have a slightly fruity or flowery smell and a great taste
Smell and taste are important factors in identifying mushrooms, but they should not be the only criteria. It is crucial to be cautious and conservative when identifying mushrooms, as consuming the wrong variety can have serious consequences.
Some mushrooms have a slightly fruity or flowery smell and a great taste. For example, the chanterelle mushroom, which is white to yellowish-gold in colour, has a funnel shape and is incredibly meaty. It is a very popular mushroom to forage for and is found all across North America in late summer through to early winter. Chanterelles are described as smelling earthy or woody. False gills, the fact that they don't grow in clusters, and their fruity or flowery smell can help identify chanterelles, distinguishing them from poisonous jack o'lantern mushrooms, which look very similar.
Another example of a mushroom with a fruity smell is the Russula genus, which has white gills and a red and white colour combination. However, while it smells fruity, its taste is very bitter.
Fresh mushrooms typically have a pleasantly earthy smell and are dry, firm, and smooth. On the other hand, soft, mushy, shrivelled, or slimy mushrooms are not ideal. Sliminess is a sign of spoilage, which can occur due to improper storage or prolonged refrigeration. Mushrooms with an unpleasant odour should be avoided, as they may be contaminated with bacteria.
It is important to note that some of the most poisonous mushrooms, such as those from the Amanita family, may also have a slightly fruity or flowery smell. Therefore, it is crucial to consider multiple factors when identifying mushrooms and never to taste a mushroom unless you are reasonably sure it is safe.

Habitat: mushrooms grow in different habitats, like on the ground, at the edge of a trail, or in grasslands, meadows, and wooded areas
Mushrooms grow in a variety of habitats, and their appearance can differ based on their growing conditions. They can be found on the ground, at the edge of a trail, or in grasslands, meadows, and wooded areas. Some mushrooms are also found in gardens.
Chanterelles, for example, are often found on the ground at the edge of a trail in a mixed hardwood forest. They tend to grow in small clusters among hardwoods, conifers, shrubs, and bushes, usually several feet away from the base of trees. They are also found in the leaf litter of mountainous forests and among grasses and mosses.
The habitat of the northern tooth mushroom is quite specific, as it grows on dying maple trees. The Old Man of the Woods mushroom is another species that can be found in forests, particularly just off a trail in a mixed hardwood forest.
Morels, which are one of America's most popular mushrooms, can be found in almost every state except Florida and Arizona, which are too hot and arid for them to thrive. They grow in moist areas and on specific tree types, including ash, tulip, oak, hickory, sycamore, cottonwood, maple, beech, conifers, and apples.
Oyster mushrooms, or Pleurotus, often grow on wood or debris, and are very common in wooded areas. They are usually bright in colour and have white or creamy gills.
Porcini mushrooms can be found near spruces, firs, and pines.
