New cycnodes - uh oh, need help

[Lagoon]

Hi gang, So I finally got brave and picked up 2 new cycnodes last saturday -- Taiwan gold & wine delight, got troubles with both of them

First 3 pics of taiwan, love the flowers but the roots are like paper - cold wet paper. I have what appears to be a new bulb comming from the base (no roots yet).
I'm guessing I just cut off the roots, place inside pot and wait for new growths?

The last photo of wine delight, these darker growths did'nt look bad at all when I got them, but it sure has progressed quickly. Looks like 1 of the mature bulbs is rotting - its has new growths comming from it, the roots have already started to form (they grow so fast) I'm thinking the wise thing to do is cut out the rot, apply fungicide and pray it doesn't continue to spread.

I have not had a good look at the roots yet but the ones on top are very much light the Taiwan gold - thin dried out paper

I'm new to cycnodes, I could really use to advice for these sweet little trouble makers.

Many Thanks
