Black stains on C. sanguinea

martin_harding

Hi all, 

I've noticed some black marks on my C. sanguinea over the last few days and I have no idea what it may be.  They are concentrated around the tips of the stems, and the discoloured stems have no growth on them at all.  Can anyone give me any idea as to what it might be, and what I can do to get rid of it? 

Thanks in advance, 

Martin

This is the stain in question - should have done this for the original post but hey ho
