“Turning a backyard compost pile will commonly expose visible networks of mycelia that have formed on the decaying organic material within. Compost is an essential soil amendment and fertilizer for organic farming and gardening. Composting can divert a substantial fraction of municipal solid waste from landfill.”(wikipedia)

"Around 90% of land plants are in mutually-beneficial relationships with fungi. The 19th-century German biologist Albert Bernard Frank coined the word "mycorrhiza" to describe these partnerships, in which the fungus colonises the roots of the plant."

Life cycle

Mycelium/Hyphae

“Mycelium is the vegetative part of a fungus, consisting of a mass of branching, thread-like hyphae. A typical single spore germinates into a homokaryotic mycelium, which cannot reproduce sexually; when two compatible homokaryotic mycelia join and form a dikaryotic mycelium; that mycelium may form fruiting bodies such as mushrooms.”(wikipedia)

“One of the primary roles of fungi in an ecosystem is to decompose organic compounds”(wikipedia)

“Turning a backyard compost pile will commonly expose visible networks of mycelia that have formed on the decaying organic material within. Compost is an essential soil amendment and fertilizer for organic farming and gardening. Composting can divert a substantial fraction of municipal solid waste from landfill.”(wikipedia)

Common mycorrhizal networks (CMN)

Fungus

“The team tested the soil in the cylinders for two compounds made by the marigolds, which can slow the growth of other plants and kill nematode worms. In the cylinders where the fungi were allowed to grow, levels of the two compounds were 179% and 278% higher than in cylinders without fungi. That suggests the mycelia really did transport the toxins.”(ref http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0027195) The team then grew lettuce seedlings in the soil from both sets of containers. After 25 days, those grown in the more toxin-rich soil weighed 40% less than those in soil isolated from the mycelia. "These experiments show the fungal networks can transport these chemicals in high enough concentrations to affect plant growth,” says Morris, who is now based at Xavier University in Cincinnati, Ohio.

As a result of this growing body of evidence, many biologists have started using the term "wood wide web" to describe the communications services that fungi provide to plants and other organisms.

Sclerotium

A sclerotium (plural sclerotia, from Greek skleros - hard) is a compact mass of hardened fungal mycelium containing food reserves.

Features

  • Transport of allelochemicals; Allelopathy, a phenomenon where compounds produced by one plant limit the growth of surrounding plants
  • Mycoremediation
  • Mycofiltration
