Demystifying Mycelium
Acting as the digestive system for mushrooms, the mycelium, a fungi root structure, actively searches for nutrients and processes them into a digestible format for the fungus. The residue of this process not only nourishes the surrounding soil but also produces a nutrient-rich biomass, making it an excellent mulch for gardening.
Besides its role in mushroom development, mycelium networks are instrumental for the health and growth of many land plants, including trees. For example, tree roots engage in a symbiotic exchange with fungi, where the tree provides sugars as carbon to the fungus, and in return, the fungus offers essential minerals like nitrogen and phosphorus to the tree.

Fascinatingly, mycelium networks function as an underground communication network among plants, akin to neural networks in human brains. Recent scientific studies suggest that plants and trees may have rudimentary nervous systems that fungi may influence, affecting processes like communication, memory, and learning. Moreover, mycelium improves soil health by decomposing organic matter and neutralizing any pollutants.
If you’re intrigued by the prospect of cultivating magic mushrooms, gaining an understanding of mycelium development is vital. Although the cultivation process can be daunting for novices, familiarizing yourself with mycelium is an essential first step. While buying mushrooms from Microdosing Mushrooms Canada online is always an option, learning about mycelium can enrich your cultivation journey.
How Mycelium Grows
Upon encountering a favourable environment, fungal spores trigger the growth of two mycelium types. The primary or monokaryotic mycelium, the first type, is characterized by a single nucleus in each cell and is typically invisible to the naked eye. The secondary or dikaryotic mycelium, the second type, is visible and houses two nuclei per cell.
When fungal spores germinate, they form the primary mycelium, also known as the monokaryotic mycelium. Upon encountering another compatible monokaryotic mycelium, they can combine to generate the secondary stage, referred to as the dikaryotic mycelium. This secondary mycelium has the potential to produce mushrooms or sclerotia.
Mycelia Types
Mycelia can be categorized into three types, with two of them signaling successful cultivation.
- Rhizomorphic mycelia extend like strings and are easily identifiable. They and all other mycelia are made up of units called hyphae. The rhizomorphs are the network of grouped hyphae. Rhizomorphic mycelia first extend, then send chemical signals back to the colony indicating the suitability of the area ahead for nutrient supply. The remaining mycelia then follow. The hyphae at the tip of the rhizomorphic mycelia release peroxidase, a substance that breaks down the material in front for nourishment. The hyphae then spread over the material, dispersing the nutrients throughout the colony. This type of mycelia is often chosen by cultivators because it increases the likelihood of mushroom production as the Rhizomorphic mycelia sprout from the substrate.
- Tomentose, or “Fluffy” mycelia, have a unique arrangement of strands that are more similar to Rhizomorphic mycelia than they are different. The strands, which may not be immediately evident, are actually there. Their cotton-ball-like appearance indicates that the strands are clustered together. Whether your mycelia develop tomentose or rhizomorphic characteristics largely depends on the growing conditions. There is an ongoing debate among cultivators regarding the influence of the type of mycelia on growth rate or harvest abundance.
- Aerial mycelia appear when the conditions for growth are less than ideal. In such cases, the mycelia tend to grow outwards instead of spreading across the medium or forming a ball. Often mistaken for bacterial infection, this type of mycelia can disrupt your mushroom cultivation, causing weaker, smaller mushrooms. Aerial mycelia usually happens due to inadequate fresh air exchange and excessive humidity.
Is it Mould or Mycelium?
It’s critical to distinguish between mould and mycelium. If green, blue, grey, or black patches appear on or in your fruiting box, it’s likely that your culture is contaminated. Discoloration is the main sign. However, blue spots could simply be bruises.
Usually, cobweb moulds are quite conspicuous. Instead of the bright The Mycelium is commonly recognized by its distinct greyish-white color and stringy, fluffy texture. Although cobweb and green moulds pose no threat to humans, they can adversely impact the health of your mushrooms.
