all over the stem, leaf-stalks, and ruined leaves; the effect of the fungus growth is to decompose the tissues of the plant.  At B, a transverse section through the stem is illustrated and magnified twenty diameters.  The section cuts through several of the abscess-like pustules, and it is seen how completely embedded they are in the flesh of the plant.  At C, a pustule is seen in section, enlarged sixty diameters to show more clearly the innumerable spores, or ‘seeds,’ disposed in necklace-like fashion, which are destined to reproduce the pest in future seasons.  Another disease of Violets in autumn is caused by a fungus named =Urocystis violae=.  This fungus causes gouty swellings to form on the stalks and principal veins.  These swellings at length burst, exhibit black patches, and discharge sooty spores.  The fungoid disease named =Phyllosticta violae= is frequently common on Violet leaves in June.  In this the spots are whitish.  No cure is known, and it is always well to burn or deeply bury all infected leaves or plants.
