Salix Caprea bark problem

Whilst doing some minor tree surgery on our pussy willow (Sallow) I was alarmed to notice that the small cracks all over mature branches are vivid scarlet. Is this a disease? I can find no reference to anything similar.

    Any pics? Sounds like it might be coral spot or something similar
  • Here's a picture of the problem, which covers almost all the branches.

    Coral spot fungus? Salix caprea is prone to fungal diseases (and pests).

  • Although the colour is similar, I don't think it's Coral Spot because it's not raised from the bark surface at all, rather lying in cracks in the bark. Others have suggested a fairly harmless fungus resulting from damp weather conditions, which should clear.
