Mycelium is an important food source for many soil invertebrates. They are vital to agriculture and are important to almost all species of plants, many species co-evolving with the fungi. Mycelium is a primary factor in some plants' health, nutrient intake and growth, with mycelium being a major factor to plant fitness.
While movement of resources between plants connected to the same mycorrhizal network has been shown, it is often unclear whether the transfer is direct, as though the mycelium is forming a literal “pipeline,” or indirect, such as nutrients being released into the soil by fungi and then picked up by neighboring plants.

A mycorrhiza (from Ancient Greek μύκης (múkēs) ' fungus ' and ῥίζα (rhíza) ' root '; pl. mycorrhizae, mycorrhiza, or mycorrhizas) [1] is a symbiotic association between a fungus and a plant. [2] The term mycorrhiza refers to the role of the fungus in the plant's rhizosphere, the plant root system and its surroundings.
Ectomycorrhizal extramatrical mycelium (also known as extraradical mycelium) is the collection of filamentous fungal hyphae emanating from ectomycorrhizas. It may be composed of fine, hydrophilic hypha which branches frequently to explore and exploit the soil matrix or may aggregate to form rhizomorphs ; highly differentiated, hydrophobic ...
The English word fungus is directly adopted from the Latin fungus (mushroom), used in the writings of Horace and Pliny. [10] This in turn is derived from the Greek word sphongos (σφόγγος 'sponge'), which refers to the macroscopic structures and morphology of mushrooms and molds; [11] the root is also used in other languages, such as the German Schwamm ('sponge') and Schimmel ('mold').
Ectomycorrhizal symbiosis, showing root tips with fungal mycelium from the genus Amanita. An ectomycorrhiza (from Greek ἐκτός ektos, "outside", μύκης mykes, "fungus", and ῥίζα rhiza, "root"; pl. ectomycorrhizas or ectomycorrhizae, abbreviated EcM) is a form of symbiotic relationship that occurs between a fungal symbiont, or mycobiont, and the roots of various plant species.
Fungi that possess these structures can compete and grow in harsh conditions. [ 7 ] Rhizomorphs are sometimes called mycelial cords, although they are structurally different: mycelial cords are less complex and have a loose network of hyphae giving an appearance of a fan-like mat, [ 6 ] while rhizomorphs are more complex organs that have ...
dicaryotic, secondary mycelium. A single cell (dikaryon) having two genetically distinct haploid nuclei. [96] dimorphic. dimorphism. Having two forms, e.g. both yeast and mycelial forms. Examples include Histoplasma and Sporothrix. [97] diplanetism A life cycle with two types of zoospores (dimorphic), primary and secondary. [98] Discomycetes ...
