The chlamydospores are the main survival structure, and they can live in the soil for up to four months. The additional formation of sclerotia allows U. virens to survive even longer, almost up to a year. These sclerotia, which can be present either on or below the surface of the soil, mature to form an ascocarp (fruiting body).
The chlamydospores are the key survival mechanism, remaining viable in the soil for up to four months. Additionally, the formation of sclerotia enables U. virens to survive even longer, typically lasting almost a year.
