Deciphering Mycelium
Mycelium, the root system of fungi, operates as the digestive system of mushrooms. It locates nutrients, converts them into a usable form for the fungus, and in turn nourishes the fungus. The byproduct of this process enriches the soil around it, providing vital nutrients to other plants and creating a nutrient-rich biomass that serves as an excellent mulch for gardening.
Alongside their function in mushroom growth, mycelium networks are critical for the health and expansion of numerous terrestrial plants, including trees. For example, tree roots and fungi conduct a symbiotic exchange: the tree provides the fungus with carbon in the form of sugars, and in reciprocation, the fungus supplies the tree with crucial minerals like nitrogen and phosphorus.

Intriguingly, mycelium networks function as a subterranean communication system among plants, akin to the neural networks in our brains. Current scientific research indicates that plants and trees may have basic nervous systems that fungi could possibly influence, impacting processes such as communication, memory, and learning. Furthermore, mycelium improves soil health by decomposing organic matter and purifying any present pollutants.
If you’re keen on growing magic mushrooms, comprehending the growth of mycelium is essential. Although the cultivation process might be daunting for novices, acquiring knowledge about mycelium is a vital initial step. While buying mushrooms from Shrooms Canada online is always a possibility, understanding mycelium can enrich your cultivation experience.
Understanding Mycelium’s Growth Process
When fungal spores find a suitable growth environment, they trigger the formation of two kinds of mycelium. The first, known as primary or monokaryotic mycelium, is distinguished by a single nucleus in each cell and is usually invisible to the naked eye. The second, termed secondary or dikaryotic mycelium, is visible and contains two nuclei per cell.
Upon germinating, fungal spores initiate the creation of the primary mycelium, also known as the monokaryotic mycelium. When this encounters a compatible monokaryotic mycelium, they combine to form the dikaryotic mycelium, which is the second stage. This secondary mycelium holds the potential to produce mushrooms or sclerotia.
Types of Mycelia
There are three different categories of mycelia, two of which suggest successful cultivation.
- Rhizomorphic mycelia expand in a string-like fashion. They are easily recognizable and consist of units called hyphae. The interconnected network of these hyphae is known as rhizomorphs. Initially, rhizomorphic mycelia spread out and then send back chemical signals to the colony, indicating the suitability of the area ahead for nutrient provision. The remaining mycelia follow suit. The hyphae at the forefront of the rhizomorphic mycelia release peroxidase, an enzyme that breaks down the material ahead for food. The hyphae extend over this material, distributing the nutrients throughout the colony. This mycelia type is preferred by many cultivators due to its increased propensity for mushroom generation from the substrate.
- Tomentose, or “Fluffy” mycelia, have several similarities with Rhizomorphic mycelia, but their fluffy strands are arranged differently. Although these strands may not be immediately visible, they are indeed present, clustering together to give a cotton-ball-like appearance. The development of your mycelia as tomentose or rhizomorphic largely depends on the growth environment. Cultivators continue to debate whether the type of mycelia influences the growth rate or harvest yield.
- Aerial mycelia develop when the growth conditions are less than ideal. Under such circumstances, the mycelia grow outward rather than spreading across the medium or forming a ball. Often confused with bacterial infection, this type of mycelia can interfere with your mushroom cultivation, leading to smaller, weaker mushrooms. The emergence of aerial mycelia is typically due to insufficient fresh air exchange and excessive humidity.
Is it Mould or Mycelium?
It’s essential to distinguish between mould and mycelium. If you notice green, blue, grey, or black patches on or within your fruiting box, it’s likely that your culture has been contaminated. Discoloration is the primary sign. However, blue spots could simply be bruises and not necessarily a sign of contamination.
Cobweb moulds are usually quite noticeable. Unlike the bright The off-white color of Mycelium usually displays a grey tint and exhibits a string-like, fluffy texture. Although cobweb moulds and green moulds pose no threat to humans, they can adversely impact the well-being of your mushrooms.
