COTTONY MOLD The fungus Sderotinia sclerotiorum is referred to rather frequently in this circular as the cause of diseases of various plants. In such cases it causes a rotting of stems, roots, leaves, fruit, or other fleshy parts,. Fig. 40.—Cottony-mold fungus. (From Ext. Cir. 118.) and develops an abundant growth of pure-white, cottony, fluffy mold upon the affected tissue (fig. 40). This is a soil fungus which ordinarily grows upon dead vegetable matter, but when moisture is abundant, it may attack living plants, fruit, or vegetables. The fungus forms no spores of any kind upon the white mold, but when there is plenty of moisture, this growth may spread very rapidly. Embedded in it and upon the affected plant parts are seen roundish, black, solid bodies of various sizes up to about % inch long and % inch in width or even.
