These bodies are called sclerotia, and are the most distinctive indication of this disease. A less serious root rot of clovers, caused by the fungus Rhizoctonia, may show similar general symptoms, but the sclerotia are lacking. Cause.—The cause of this disease is a fungus, Sclerotinia, that may live over in the soil on decaying vegetable material from one season to the next. The sclerotia are particularly adapted for with- standing extremes of temperature and moistur
