This mycelium grows only on the surface, unlike themycelia of Peronospora and other parasitic fungi which enter the tis-sues of the host plant. It obtains its nourishment from the epidermalcells of the plant attacked, by means of suckers—haustoria—whichpenetrate these outer cells. The outer cells thus attacked become darkcolored. The fact that the Oidium does not penetrate the tissues of thevine much facilitates its control and renders its destruction possible atany stage
