（重定向自Glomus intraradices）
Rhizophagus irregularis (previously known as Glomus intraradices ) is an arbuscular mycorrhizal fungus used as a soil inoculant in agriculture and horticulture. In addition, it is one of the best mycorrhizal varieties of fungi available to mycoforestry, but it "has virtually no market value as an edible or medicinal mushroom"
