How Do Truffles Grow? Mycorrhiza and the Life Cycle

Truffles develop underground in association with host plant roots. Learn what truffle mycelium and mycorrhiza are and how fruiting bodies develop.

02Explanation

The cycle connects spores, germination, mycelium growth, mycorrhiza with host roots, and fruiting-body formation and maturation. Some fertilisation and early fruiting stages remain incompletely understood; timing and outcomes depend on species and habitat.

Soil section under a tree: host roots with mycorrhizal tips, mycelium spreading through the soil, a cut mature fruiting body and spores. Numbers 01–05 mark the cycle stages listed below.
