My rot was further down on the rhizome too. I didn't see any damage to the rhizomes, just all of a sudden noticed they were getting mushy. I didn't notice a smell, either. My friend suggested cutting out/off the mushy parts then soaking them for 30 minutes in a 10 percent bleach solution, so I did that. Then set them out to let the cuts scab over and wouldn't you know, the rain started again. Sheesh! Do you need to do something special for Mustard Seed Fungus? These were in a new raised bed that I used all Kellogg's raised bed mix in. There wasn't any moisture against the rhizome.
