White radishes are supposed to be more susceptible than are red, globe type varieties. You might want to put a couple of the presumably infected roots in a plastic bag in your refrigerator. The fungus should grow out of the spots as a "fuzzy" growth if that is the cause. If that happens, consider sending infected roots to your state university's Plant Disease Clinic. Dave
