Basic Definition of Mycelium

What is Mycelium

Mycelium represents the collective network of filamentous structures known as hyphae that grow from fungal spores. This crucial component of most fungi is typically found within the soil or other substrates where the fungi grow. As one of the primary structures of a fungal organism, it serves not only as the fungus’s source of nourishment but as a significant contributor to several other vital processes.

Structure of Mycelium

the actual structure of mycelium is quite complex. It’s composed of a network of hyphae, microscopic strands that expand and branch out as they grow. Each hypha comprises one or multiple cells surrounded by a protective cell wall composed of chitin, a biopolymer also found in the exoskeletons of insects. These hyphae interweave together, forming a vast and often intricate web that makes up the mycelium.

Functions and Role of Mycelium

While often unseen, mycelium plays an integral role in the way that fungi, and by extension, ecosystems function. Firstly, the mycelium is responsible for nutrient acquisition, absorbing essential elements such as nitrogen, phosphorus and water from the environment. Additionally, it is fundamental in the process of decomposition, breaking down organic matter, such as dead plants and animals, into elements that can then be used by other organisms. In doing so, mycelium not only aids the survival of fungi but contributes significantly to nutrient cycling within ecosystems.

Mycelium in Fungi

Mushroom Mycelium

In mushroom-producing fungi, mycelium serves as the actual body of the mushroom organism. All visible parts of mushrooms, whether it’s the cap, the stem, or the gills under the cap, are reproductive structures that grow from an extensive mycelial network that remains largely hidden from sight underground. It is this part of the fungus that absorbs nutrients, supports the fruiting body’s development, and allows for reproduction.

Yeast Mycelium

Although less complex than their mushroom counterparts, yeast fungi also produce mycelium. In yeast, however, mycelium often forms as a clump of cells rather than a network of filaments. This clump can then divide and grow, much like its more complex mycelial counterparts.

Truffle Mycelium

In truffle fungi, the mycelium forms a symbiotic relationship with certain types of trees, referred to as mycorrhizal association. The mycelium grows around the tree roots absorbing minerals and water, and in return, the tree gets nutrients from the fungus. This relationship is essential for truffle formation, which develops as a fruiting body of the fungus underground.

Mycelium in Molds

In the case of molds, the mycelium serves a central role in both reproduction and feeding. The network of hyphae that make up the mycelium absorb nutrients from the substrate on which they grow. When the mold’s environment is opportune, spores are produced, often on specialized hyphae structures within the mold’s mycelium.

Mycelium in Building Materials

Mycelium in Bio-fabrication

In the realm of bio-fabrication, mycelium is gaining recognition as a prominent material. When provided with a suitable environment and nutrients, the mycelium is capable of growing into various forms and densities. Its ability to adhere to different substances makes it an excellent natural adhesive, which, when dehydrated, can be incredibly sturdy and strong.

Development of Mycelium-based Materials

Mycelium-based materials are increasingly used in a range of applications, from building materials to packaging. Developers grow the mycelium on a substrate, such as agricultural waste, where it breaks down and transforms the substrate into a solid, moldable mass. Several start-ups and research groups are currently exploring this area, and mycelium-based products already exist on the market.
