The presence of the mycelium in the host is first known through the appearance of reddish spots or lines on the stems and leaves in late spring or early sum- mer. The reddish spots or lines are regions of spore production. They are pustules or blister- like structures caused by masses of spore-bearing hyphae which push up the epidermis until it is finally ruptured (Fig. 353). The reddish color of the pustules is due to the reddish color of the spores. These sp
