It looks more like an original Christmas Cactus to me and if so you are lucky. It's obvious the roots are not happy. They are either being over watered, in a mix that is too compact, staying wet too long, or left to dry out too long. Can you give us a description of mix the roots are in? Can you take a close up shot of the mix? How often do you water? When do you water? is that mix compacted? When was the last re pot? What kind of mix? You need to give those roots a mix that allows good oxygen exchange as soon as possible.
