Mycorrhiza
A mycorrhiza (from Ancient Greek μύκης (múkēs) 'fungus' and ῥίζα (rhíza) 'root'; pl. mycorrhizae, mycorrhiza, or mycorrhizas) is a symbiotic association between a fungus and a plant, in which fungal hyphae and plant roots become interconnected and form an interface on the cellular level. The term mycorrhiza refers to the role of the fungus in the plant's rhizosphere, the plant root system and its surroundings.
