Introduction to Mushroom
Definition and Characteristics of Mushrooms
Definition: Mushrooms are the fruiting bodies of certain fungi, typically characterized by a stem, cap, and gills or pores on the underside of the cap.
Physical Characteristics
○ Cap: The umbrella-like top part that can come in various shapes, sizes, and colors.
○ Stem: The stalk that supports the cap.
○ Gills/Pores: Located on the underside of the cap, these structures produce and release spores.
○ Spores: Microscopic reproductive units that disperse to form new fungal growth.
○ Mycelium: The network of fungal threads (hyphae) that make up the main body
of the fungus, usually hidden in soil or decaying material.
Classification within the Fungal Kingdom
Kingdom Fungi: Mushrooms belong to this kingdom, distinct from plants, animals, and
bacteria.
● Phylum: The majority of mushrooms fall under the phylum Basidiomycota, known for
producing spores on basidia. Some belong to the phylum Ascomycota, producing spores
in asci.
● Classes and Orders: Further classifications based on specific features, such as gill structure, spore color, and ecological roles.
● Families and Genera: Grouped by more specific characteristics, leading to various
genera (e.g., Agaricus, Amanita, Boletus).
● Species: The most specific level, identifying individual types of mushrooms.
Differences Between Mushrooms and Other Fungi
● Fruiting Body: Mushrooms have a distinct fruiting body (cap and stem), while many
fungi do not produce such structures (e.g., molds, yeasts).
● Habitat: Mushrooms are often found in soil or on decaying organic matter, whereas
other fungi can inhabit a wide range of environments, including living organisms and
industrial settings.
● Reproduction: Mushrooms primarily reproduce via spores produced in the gills or
pores, while other fungi may use different methods (e.g., budding in yeasts, spore sacs
in molds).
● Morphology: Mushrooms have a more complex and visible structure compared to many other fungi that might be microscopic or appear as simple growths.
Mushroom Biology and Ecology
The Life Cycle of Mushroom
1. Spore Release: Mushrooms produce spores in structures like gills or pores. These spores are released into the environment.
2. Germination: When spores land in a suitable environment, they germinate to form hyphae, the thread-like structures of the fungal mycelium.
3. Mycelium Growth: Hyphae grow and spread, forming a network called mycelium. This mycelium is the main body of the fungus, usually hidden in the substrate (soil,
wood, etc.).
4. Fruiting Body Formation: Under favorable conditions, the mycelium forms fruiting bodies, which are the visible mushrooms.
5. Maturation and Spore Production: The fruiting body matures, producing and
releasing spores, starting the cycle anew
Role of Mushrooms in Ecosystems
● Decomposition: Mushrooms decompose organic matter, recycling nutrients back into
the ecosystem. They break down complex organic materials like dead plants and wood
into simpler compounds, enriching the soil.
● Nutrient Cycling: By decomposing organic matter, mushrooms help cycle essential nutrients like carbon, nitrogen, and phosphorus through ecosystems.
● Habitat Creation: The decomposition process creates habitats for various
microorganisms and small invertebrates, contributing to biodiversity.
Symbiotic Relationships with Plants (Mycorrhizae) and Animals
Mycorrhizae:
○ Ectomycorrhizae: Fungi form a sheath around plant roots and extend into the soil, enhancing water and nutrient absorption. Common in trees like oaks and pines.
○ Endomycorrhizae (Arbuscular Mycorrhizae): Fungi penetrate plant root cells, forming arbuscules that facilitate nutrient exchange. Common in many crops and grasses.
○ Benefits to Plants: Improved nutrient uptake (especially phosphorus), enhanced water absorption, increased resistance to pathogens, and better tolerance to environmental stress.
○ Benefits to Fungi: Access to carbohydrates produced by plants through photosynthesis.
● Relationships with Animals:
○ Dispersal Agents: Animals like squirrels, deer, and insects help disperse spores by feeding on fruiting bodies.
○ Food Source: it serve as a food source for various animals, from invertebrates to mammals.
Factors Influencing Growth and Distribution
Environmental Conditions:
○ Moisture: it require a humid environment to thrive.
○ Temperature: Different species have varying temperature preferences, but most
need moderate temperatures.
○ Light: While mycelium can grow in darkness, fruiting bodies often need some
light to develop.
● Substrate: The type of organic material available (wood, leaf litter, soil, etc.) influences
which species can grow.
● pH Levels: Most of them prefer slightly acidic to neutral pH levels in their growing
substrate.
● Competition and Predation: Competition with other fungi and microorganisms, as
well as predation by animals, can impact growth and distribution.
● Human Activity: Logging, agriculture, urbanization, and pollution can alter habitats
and affect populations.
2. Types of Mushroom
Edible Mushrooms

○ Color: Varies widely; can change with age or environmental conditions.
○ Texture: Smooth, scaly, slimy, or dry.
○ Margin: The edge of the cap; can be smooth, striated, or rolled.
● Gills/Pores:
○ Attachment: How they connect to the stem (free, attached, decurrent).
○ Color: Can help distinguish between species; changes as the it matures.
○ Spacing: Crowded, distant, or somewhere in between.
● Stem (Stipe):
○ Shape: Cylindrical, club-shaped, bulbous.
○ Texture: Smooth, fibrous, scaly. ○ Presence of Ring (Annulus): A ring around the stem left from the partial veil.
○ Base: May have a bulb or volva (sac-like structure).
● Spore Print:
○ Color: Obtained by placing the cap on a white or black surface; critical for identification.
● Odor: Can range from sweet to foul; some species have distinctive smells.
● Habitat: Where the it is growing (type of trees, soil, decaying wood).
3.2 Safety Tips for Foraging
● Never Eat Unknown Mushrooms: Only consume mushrooms that have been positively identified by an expert.
● Learn from Experts: Join local mycological societies, take guided foraging trips, and study reputable field guides.
● Check Multiple Sources: Use several identification features and cross-reference with reliable sources.
● Avoid Look-Alikes: Many edible mushrooms have poisonous doppelgängers.

● Paddy straw
● Formalin (formaldehyde solution)
● Bavistin (carbendazim, a fungicide)
● Water
● Large drum or container for soaking straw
● Plastic bags or containers for growing
● Clean workspace
Preparation
1. Gather Supplies: Ensure you have all the materials ready and your workspace is clean
to prevent contamination.
2. Cut the Straw: Cut the paddy straw into pieces about 5-10 cm in length. This will help
in better handling and even distribution of spawn. Substrate Preparation
3. Soak the Straw:
○ Fill the drum or container with water.
○ Add formalin to the water at a concentration of 0.5% (500 ml formalin in 100
liters of water).
○ Add Bavistin at a concentration of 0.1% (100 g Bavistin in 100 liters of water).
○ Mix the solution thoroughly.
4. Submerge the Straw:
○ Submerge the cut paddy straw in the prepared solution.
○ Place a weight on top to ensure the straw remains fully submerged.
○ Soak for 12-24 hours to sterilize and hydrate the straw.
5. Drain the Straw:
○ After soaking, drain the straw completely.
○ Spread it out on a clean surface and let it drain for 1-2 hours to remove excess
water. The straw should be moist but not dripping.
Inoculation
6. Prepare the Spawn: Break the spawn into small pieces for even distribution.
7. Layering:
○ Take a clean plastic bag or container.
○ Place a layer of prepared paddy straw at the bottom (about 10-15 cm thick).
○ Sprinkle a layer of spawn evenly over the straw.
○ Repeat the process, alternating layers of straw and spawn, until the container is full.
○ Finish with a top layer of straw.
Incubation
9. Incubate:
○ Place the inoculated bags in a dark, warm area with a temperature between 20-25°C (68-77°F).
○ Maintain high humidity (85-90%) by misting the area if necessary.
○ Ensure good ventilation to avoid the buildup of carbon dioxide.
○ Incubation will last 15-20 days, during which the mycelium will fully colonize the straw. You’ll notice the white mycelium spreading throughout the straw.
Fruiting
10. Fruiting Conditions:
○ Move the colonized bags to a fruiting area with indirect light.
○ Maintain a slightly cooler temperature (15-20°C or 59-68°F).
