Vibernum bush dying

I have a Vibernum bush which is slowly dying. It has a fungus growing on the branches most of which is a grey colour but there are some bits that are more of a yellow shade. I  have cut out a lot of the bad branches but still leaves are turning brown and it is going down hill.

I have taken some pictures which I thought I would be able to attache to this message but as yet I have not found a way of doing so. I see there is a gallery but cannot fathom out how to put the pictures on there so you could see exactly what the problem is.

Can anyone help please??

I take that back!

You had added to the gallery, its just the pictures were waiting for approval.

Here they are (approved for you):

Thank you. I added two more which may be too big??

Thanks for your advice,

RonBin
