A glycoprotein produced by the hyphae of mycorrhizal fungi that sequesters large amounts of carbon in the soil and improves soil structure by acting as a clumping agent.

[New Latin Glomālēs, former order name (now Glomerālēs) of the fungi producing the glycoprotein (from Glomus, type genus, from Latin glomus, glomer-, ball of yarn, in reference to the peridia of the genus, covered with numerous threadlike hyphae) + -in.]
