Decoding Mycelium
Mycelium, the root structure of fungi, acts essentially as the digestive system for mushrooms. It scouts for nutrients, converts them into an absorbable form for the fungus, and thereby nourishes the fungus. The byproduct of this cycle enriches the nearby soil, offering necessary nutrients to other plants, and creates a nutrient-rich biomass that is perfect for gardening mulch.
Beyond their contribution to mushroom growth, mycelium networks are crucial to the health and expansion of various land-based plants, including trees. For example, tree roots form a symbiotic relationship with fungi: the tree offers the fungus carbon in the form of sugars, and reciprocally, the fungus furnishes the tree with key minerals such as nitrogen and phosphorus. You can learn more about this interaction here.
Intriguingly, mycelium networks function as a kind of subterranean communication network among plants, akin to the neural networks in our brain. Recent studies suggest that plants and trees might have rudimentary nervous systems that fungi could possibly influence, impacting functions like communication, memory, and learning. Plus, mycelium aids in maintaining soil health by decomposing decaying organic matter and neutralizing any present pollutants.
If you have a keen interest in cultivating magic mushrooms, it’s fundamental to understand the growth process of mycelium. Even though the cultivation process might seem daunting for novices, learning about mycelium is an essential first step. While buying mushrooms from Mushrooms Online Canada online is always a possibility, gaining knowledge about mycelium can enrich your cultivation journey.
Mycelium Growth Process
When fungal spores find an environment apt for growth, they trigger the development of two types of mycelium. The first type, referred to as primary or monokaryotic mycelium, is identified by a single nucleus in each cell. This type of mycelium isn’t typically visible to the unaided eye. The second type, termed secondary or dikaryotic mycelium, can be seen and features two nuclei in each cell.
As the fungal spores germinate, they form an initial or primary mycelium known as the monokaryotic mycelium. Upon coming into contact with another compatible monokaryotic mycelium, they can fuse together to create a second stage known as the dikaryotic mycelium. This secondary mycelium is capable of producing mushrooms or sclerotia.
Mycelium Categories
Mycelia are primarily classified into three types, of which two are indicative of successful cultivation.
- Rhizomorphic mycelia extend similar to strings, and are easily identifiable. Like all mycelia, these are composed of units called hyphae, which form a network known as rhizomorphs. Initially, rhizomorphic mycelia spread out and then send back chemical signals to the colony, indicating that the front area is suitable for nutrient provision. The remaining mycelia then follow suit. The hyphae at the rhizomorphic mycelia’s tip release peroxidase, a substance that breaks down the material in front of it for food. The hyphae then spread over the material, distributing nutrients throughout the colony. Many cultivators prefer this type of mycelia due to its increased mushroom production probability as the Rhizomorphic mycelia sprout from the substrate.
- Tomentose or “Fluffy” mycelia are quite similar to Rhizomorphic mycelia, but they have a unique strand arrangement. While the strands might not be easily noticeable, they are indeed there. Their cotton-ball-like appearance indicates that the strands are bunched together. The development of your mycelia into tomentose or rhizomorphic traits largely depends on the growing environment. There is an ongoing debate among cultivators regarding the impact of the mycelia type on growth rate or harvest abundance.
- Aerial mycelia appear when the growth conditions are less than ideal. In such cases, the mycelia tend to grow outward instead of spreading across the medium or forming a ball. Often misidentified as a bacterial infection, this type of mycelia can hinder your mushroom cultivation, leading to smaller, weaker mushrooms. Aerial mycelia typically occur due to inadequate fresh air exchange and excessive humidity.
Is it Mould or Mycelium?
Distinguishing between mould and mycelium is vital. If you notice patches of green, blue, grey, or black on or in your fruiting box, it’s likely that your culture is contaminated. Discolouration is a primary indicator. However, keep in mind that blue spots could simply be bruises.
Cobweb moulds are typically quite noticeable. Contrasting the bright The Mycelium usually appears in a light grey shade with a fluffy, string-like texture. While cobweb and green moulds pose no threat to human health, they can negatively impact the wellbeing of your mushrooms.
