It appears that neither number of stomata nor epidermal hairs per unit area are correlated with susceptibility. The parasitic always penetrates into the tissues even in resistant pods. In this last instance, an equilibrium is established between the host cells and the fungus which only grows very slowly. A relation similar to symbiosis is developed. Resistance to the fungus lies in a layer of parenchymatous cells some ten deep under the epidermis
