. Fig. 20.^^reeii rot of apricots on the tips of young fruits. A "jacket" is still adhering on the center fruit; the rot usually starts under the jacket. The fungus which causes green rot is the so-called "cottony mold" fungus, Sclerotinia sclerotiorum, a snow-white mold which develops upon mustard, vetch, alfalfa, weeds, or any thick-growing surface vege- tation and produces its spores only on the soil (p. 137), whence they are distributed by wind. These spores are produced more or less contin- uously from December to May and are probably abundant every year.
