VERTNI
Verticillium nigrescens (now often called Gibellulopsis nigrescens) is a mostly saprophytic soil-borne fungus and a weak or opportunistic plant pathogen. It survives in soil and plant debris mainly as chlamydospores and can infect roots when germination is triggered by root exudates. Transmission occurs through soil and possibly contaminated plant material, but there is no confirmed evidence of seed transmission.
