It causes verticillium wilt in some plant species, including Ailanthus altissima. [1] [2] The fungus produces a resting mycelium characterized by brown-pigmented hyphae. It is most closely related to V. dahliae and V. alfalfae. [3] Common hop plants showing foliar symptoms of Verticillium wilt caused by Verticillium albo-atrum on a field at ...
