Compatible haploid hyphae fuse to produce a dikaryotic mycelium. The sporangiospores germinate to form the haploid hyphae of a new mycelium. These growth processes lead to the development of a mycelium, an interconnected network of hyphae. Upon germination, a new haploid mycelium or sporangium is formed. Spores are another inoculation option, but are less developed than established mycelium. The fungus grows inside the plant as a dikaryotic mycelium. Through the mycelium, a fungus absorbs nutrients from its environment. After dispersal, the ascospores may germinate and form a new haploid mycelium. The soybeans have to cool down to allow spore germination and abundant growth of mycelium. Fungal colonies composed of mycelium are found in and on soil and many other substrates. Bacteria feed on the exudates released by mycelium and colonize soil surrounding them. The use of fungal mycelium to accomplish this has been termed mycofiltration. Lipid biosynthesis also occurs in the intraradical mycelium. They form a complex substrate mycelium that aids in scavenging organic compounds from their substrates. Mycoremediation or breaking down of hydrocarbon by mycelium and mushrooms is possible.
