Grasping the Concept of Mycelium
Mycelium refers to the root-like structure of fungi and acts as the digestive system for mushrooms. Its primary role is to extract nutrients, modify them into an absorbable form for the fungus, thereby nourishing it. The remnants of this process enrich the encompassing soil with vital nutrients, creating a nutrient-rich biomass that serves as an excellent mulch for gardening.
Mycelial networks, besides facilitating mushroom growth, are integral to the healthy growth of a wide array of terrestrial plants, including trees. For example, tree roots and fungi engage in mutual exchange; trees provide fungi with carbon-rich sugars, and in turn, fungi supply trees with key minerals such as nitrogen and phosphorus.

Fascinatingly, mycelial networks function as an underground communication system among plants, akin to the neural networks in the human brain. Recent scientific studies propose that plants and trees may have basic nervous systems that fungi could potentially manipulate, impacting processes like communication, memory, and learning. Mycelium also enhances soil health by decomposing organic matter and neutralizing harmful pollutants.
If you’re contemplating cultivating magic mushrooms, it’s fundamental to understand the lifecycle of mycelium. While the cultivation process may seem daunting for novices, acquiring knowledge about mycelium forms a crucial initial step. Although purchasing mushrooms from Shroom Shop Canada online is always an option, understanding mycelium can elevate your cultivation journey.
Understanding Mycelium’s Growth Cycle
Upon encountering a suitable growth environment, fungal spores start developing two kinds of mycelium. The first, referred to as primary or monokaryotic mycelium, is characterized by each cell having a single nucleus and is typically not visible to the unaided eye. The second type, termed secondary or dikaryotic mycelium, is visible and features two nuclei in each cell.
As the fungal spores germinate, they give rise to what is known as the primary or monokaryotic mycelium. Upon encountering another monokaryotic mycelium that it’s compatible with, they fuse to create a second stage called the dikaryotic mycelium. Mushrooms or sclerotia are products of this secondary mycelium.
Mycelia Categories
Mycelia are categorized into three types, two of which are indicative of successful cultivation.
- Rhizomorphic mycelia are characterized by their string-like extensions. Comprising of units called hyphae, these mycelia are identifiable by the network of grouped hyphae known as rhizomorphs. Rhizomorphic mycelia extend first and then transmit chemical signals back to the colony, signifying that the area ahead is nutrient-rich. The rest of the mycelia then follow suit. Peroxidase, a substance that breaks down the material ahead for food, is released by the hyphae at the rhizomorphic mycelia’s tip. The hyphae then spread over the material, dispersing the nutrients throughout the colony. Many cultivators favor rhizomorphic mycelia due to its propensity to produce mushrooms as it sprouts from the substrate.
- Tomentose, or “Fluffy” mycelia, have more similarities than differences with Rhizomorphic mycelia. Their uniqueness lies in the arrangement of the fluffy mycelia strands. These strands, although not instantly visible, are present and clumped together, giving a cotton-ball-like appearance. The growing environment largely influences whether your mycelia will develop tomentose or rhizomorphic traits. There are ongoing debates among cultivators about the impact of mycelia type on the growth rate or harvest abundance.
- Aerial mycelia arise when the growing conditions are less than ideal. Under such circumstances, the mycelia tend to grow outward instead of spreading across the medium or forming a ball. Often confused with a bacterial infection, this type of mycelia can interrupt your mushroom cultivation, leading to weaker, smaller mushrooms. Aerial mycelia are typically caused by inadequate fresh air exchange and excessive humidity.
Mycelium or Mould?
It’s essential to distinguish between mould and mycelium. If green, blue, grey, or black patches are visible on or in your fruiting box, it’s likely that your culture has been contaminated. The main sign is discoloration. However, blue spots might just be bruises.
Cobweb moulds are usually quite noticeable. Contrary to the bright The Mycelium is usually characterized by its greyish-white color and a fluffy, stringy texture. It’s important to note that while cobweb moulds and green moulds pose no risk to humans, they can adversely impact the health of your mushrooms.
