Dens with no roots

[aries23]

My dens had no good roots so I trimmed the dead ones off and bagged them with a moist paper towel. After a few weeks I was going to trash them yesterday because I saw white fuzzy mold and smelled horrible. I decided to check them out anyways. So on one that still had green leaves started to grow a green root. The other one lost it leaf and turned yellow. So while I was triming more dehydrated pieces at the bottom by mistake I removed the root how disppointing !! I wonder if this plant will give me more roots or not? I cleaned them nicely and see if this will happen again!
