What You'll Learn
Natural habitat and growing conditions
Lion's mane mushrooms are native to the temperate regions of the northern hemisphere, including North America, Canada, Europe, and Asia. They are commonly found in forests and wooded areas, particularly those with deciduous trees.
These mushrooms favour dead or dying hardwood trees and logs as their natural habitat. They have a preference for certain types of hardwood, including oak, walnut, beech, maple, birch, sycamore, and black walnut. They are often found high up in the trees, growing in the wounds of dying or dead trees. Lion's mane mushrooms are typically found in late summer and fall, although they can also be found in spring and occasionally in summer.
When growing lion's mane mushrooms, it is important to replicate their natural habitat and growing conditions. They can be grown indoors in bags or containers, or outdoors on logs. If growing on logs, it is recommended to use hardwood logs such as those made from oak, maple, birch, or black walnut. It is important to maintain a temperature between 60°F and 85°F (15°C to 30°C) and a humidity level of at least 80% for successful growth.
Lion's mane mushrooms can be grown from a culture on agar, which is then used to make grain spawn. The grain spawn is added to a bulk substrate, such as wood chips or sawdust in a growing container, and kept in a humid, aired, and watered environment. Alternatively, lion's mane mushrooms can be grown from a liquid culture, although it is recommended to transfer the culture to agar for long-term storage and reuse.

Reproduction via spores
Lion's mane mushrooms (Hericium erinaceus) are known for their distinctive white, pom-pom-like appearance, resembling the mane of a lion. They are native to the northern hemisphere, commonly found in North America, Europe, and Asia. These mushrooms have a unique mode of reproduction, primarily relying on spores for propagation.
Lion's mane mushrooms are classified as Hydnoid or tooth fungi, bearing their spores on pendant (free-hanging) structures known as spines or teeth. These structures distinguish them from other fungi that produce spores on gills or pores. The spines of younger fruiting bodies are shorter, typically less than half an inch in length and white in colour. As the mushroom matures, these spines elongate, reaching up to 2 inches, and their colour transitions to yellow-brown.
The spores are produced on the downward-cascading spines, which can grow on hardwood trees, logs, or stumps. Lion's mane mushrooms have a preference for hardwoods such as beech, maple, oak, walnut, birch, and sycamore. They are often found on dead or dying trees, taking advantage of the decaying wood as a source of nutrients. The optimal temperature range for fruiting is between 55°F and 70°F (about 13°C to 21°C), making them a cool-weather fungus.
To reproduce, the lion's mane mushroom releases its spores from the spines. These spores are then dispersed by wind or other physical vectors, carrying them to new potential growth sites. Once the spores land on a suitable substrate, they can germinate and initiate the growth of new lion's mane mycelium. This process marks the beginning of the fungus's life cycle, leading to the development of new mushroom fruiting bodies over time.
Growing lion's mane mushrooms can be done both indoors and outdoors. Indoors, they can be cultivated in bags or containers, while outdoors, they are often grown on logs. Cultivating lion's mane mushrooms requires maintaining specific conditions, such as humidity levels above 80% and temperatures within the optimal range. It is important to note that growing lion's mane mushrooms on logs may require more initial setup effort and resources compared to using bags or containers. However, logs can provide a more natural growth environment, contributing to the successful maturation of the mushrooms.

Harvesting and storage
Lion's mane mushrooms can be harvested in about 6 to 8 weeks after inoculating your substrate. The mushrooms are ready to harvest when the spines are elongated and the mushroom is still relatively firm. This is typically when they are about the size of a baseball or slightly larger. Waiting too long can result in a mushy texture.
When harvesting, gently twist and pull the mushrooms from the substrate. Avoid cutting, as this can leave behind parts that may rot. Harvesting by hand helps to ensure the substrate remains intact for potential future flushes. After harvesting, check the substrate for any remaining mushroom parts and clean if necessary.
Proper processing and storage are crucial to preserving the quality of harvested Lion's Mane mushrooms. Fresh Lion's Mane mushrooms can be stored in the refrigerator for up to a week. Place them in a paper bag or wrap them in paper towels to absorb excess moisture and allow for some air circulation. Avoid washing the mushrooms before storing, as added moisture can hasten spoilage. Instead, gently brush off any dirt.
For longer storage, Lion's Mane mushrooms can be dried. Slice the mushrooms thinly and place them in a food dehydrator or an oven set at a low temperature. They can also be air-dried in a well-ventilated area. Properly dried mushrooms can be stored for several months.

Medicinal benefits
Lion's mane mushrooms have been used in traditional medicine for centuries, and modern science has identified several medicinal benefits that could be derived from them.
Firstly, lion's mane mushrooms are rich in vitamins such as thiamine, riboflavin, and niacin. They are also a good source of essential minerals such as manganese, zinc, and potassium.
Secondly, they contain bioactive substances that have beneficial effects on the body, including anti-inflammatory substances that show promise in animal studies. Research shows that lion's mane extract can help reduce the risk of heart disease by influencing major risk factors such as improving fat metabolism and lowering triglyceride levels.
Thirdly, lion's mane mushrooms contain compounds that stimulate the production of nerve growth factor (NGF), which helps grow brain cells and may enhance memory and focus. Studies have found that lion's mane mushrooms contain two special compounds, hericenones and erinacines, that can stimulate the growth of brain cells. Animal studies have found that lion's mane may help protect against Alzheimer's disease and other forms of cognitive decline.
Lastly, lion's mane mushrooms have been used as stomach remedies in traditional medicine. Extracts from lion's mane mushrooms have been found to protect against ulcers, partly by thickening the mucus in the stomach lining. Lab and animal studies also suggest that lion's mane mushrooms can slow the growth of Helicobacter pylori (H. pylori), a type of bacteria linked to many stomach ulcers.
While lion's mane mushrooms offer a range of potential medicinal benefits, it is important to note that research in humans is still limited, and more studies are needed to confirm the effectiveness and safety of these mushrooms for specific conditions.

Culinary uses
Lion's mane mushrooms are known for their culinary and medicinal properties. They are edible and have a unique texture and taste, resembling crab meat. Their flavour is nutty and slightly sweet, making them a versatile ingredient in various dishes. Here are some culinary uses for lion's mane mushrooms:
Foraging and Identification
Lion's mane mushrooms can be foraged in the wild, but they are typically found in the late summer and fall seasons in forests across Europe, North America, and Asia. They favour dead or dying hardwood trees, particularly oak, walnut, beech, maple, birch, and sycamore. The mushrooms have cascading spines and often grow in solitude, forming a single clump.
Cultivation
If you want a steady supply of lion's mane mushrooms, you can cultivate them at home. They can be grown indoors in bags or containers, or outdoors on logs. Growing them outdoors on logs requires more setup but is easier to maintain during incubation. Indoor cultivation in bags or containers is faster and more suitable for beginners. You can purchase mushroom-growing kits that provide the necessary materials and instructions.
Preparation and Cooking
When harvesting lion's mane mushrooms, pick them when their fruiting bodies are about the size of your fist and before they start to brown. You can sauté them and then freeze them for long-term storage. Lion's mane mushrooms are versatile in cooking and can be used as a meat substitute or in pasta dishes. They are known for their health benefits, including potential protection against dementia, stomach ulcers, heart disease, and diabetes.
Lion's mane mushrooms are an intriguing and delicious ingredient for culinary enthusiasts and health-conscious individuals alike. With their unique flavour and texture, these mushrooms offer a tasty and nutritious option for various dishes.
