The microflora of apple leaves and its relationship to Venturia inaequalis (CKE.) Wint..

Venturia inaequalis (Cke.) Wint., the apple s cab fungus, grows during the summer on the living leaf, producing a mycelium which develops only between the cuticle and the epidermis. But when the infected leaf dies naturally, this mycelium then grows as a saprophyte and sends its hyphae all through the tissues of the dead leaf. It is during this saprophytic part of its life cycle that the fungus passes through it s sexual stage. Ascogonial hyphae arise in the mesophyll of the dead leaves and after fertilization by antheridia from oppositely sexed thalli, initiate the perithecia.
