Endogone

Endogone is a genus of fungi in the family Endogonaceae of the division Mucoromycota. The genus has a widespread distribution, especially in temperate regions, and contains about 20 species.

Species of Endogone form underground structures called sporocarps—fruiting structures measuring between a few millimeters to in diameter, containing densely interwoven hyphae and zygospores. Sporocarps are typically found in humus-rich soil or leaf mold, or in mosses. Although most species will only produce spores in nature, the type species E. pisiformis can be made to sporulate in test tube culture when grown with conifer seedlings.
