I have a four to five year old English Ivy plant with up to 10 feet (3 m) long vines.
Three months ago I changed its pot and it remained healty for a while. Now, all of a sudden, its branches have started to dry out and die one by one. There is a strange white covering (not sure if it's fungus) just at the base of all the branches. I tried spraying hydrogen peroxide at the base but that hasn't helped.
When I repotted it three months ago in a bigger pot I used as soil a potting mix by Miracle gro. The pot has drainage holes in the bottom. The plant is indoors near a window but with indirect sunlight. I water around once a week when the upper soil is a little dry and let the excess water drain out (same as I have been doing for years).
Any suggestion would be appreciated.

All the branches dried out. I cut of a couple of junctions covered with fungus but couldn't find any turd capsules like stuff. So this might not be Sclerotinia. See these pictures:
