Rosé problem/diesease

A friend asked me what this was at root of her rambling rose. The rose is growing ok although there was dead growth at end but that could be the weather. It doesn’t look like it’s been planted very well! This stuff is growing at root level, some of it is rotten. 
Could anyone advise? Many thanks.

    It rather looks like just fungi growing on bark mulch to me. Is there bark mulch around the rose bush?

    If so, it's probably harmless and you could just remove it if it worries you (wear gloves). Roses prefer a mulch of well rotted manure in spring so you may like to use that instead. Do not let it touch the actual rose stems though.

    Thanks for reply. No there’s no bark. It could have done with manure adding to the soil at planting really. Could it be gall does that grow at roots aswell as on stems?

    The soil looks rather claggy, so possibly waterlogged and oxygen deprived as a result. Is that also some sort of plastic membrane just seen bottom right of the photo? All that may have precipitated the problem, which looks like the graft of the plant is rotting/got a fungal infection to me. Maybe even crown gall - that potato-like growth near the label looks suspect, but it’s not something I’ve ever seen so hopefully someone with more experience of that can confirm or deny..

    Rose canes store energy so it could be it still looks ok above because it’s using those reserves, but it’s slowly dying from below.

    Thanks Nollie, yes it is rather claggy & they had cut through a membrane & planted. I’m just hoping it can be saved. It’s hard to identify because whatever it is looks bit rotten!

    Rotating the photo makes it easier to see

    Since she bought it from David Austin, could she email them and see what they said?

    If the crown/graft is rotting/diseased I’m not optimistic it will survive, but it would be good to know exactly what caused it..
