Problem started last year. It didn’t blossom as it usually does in spring and same again this year. On closer inspection we have spotted this fungus on the branches, no idea what to do for it. The leaves seem to be prematurely turning as if autumn has started early as well. Totally puzzled as to what we can do for it. We have took a picture of it in the hopes that someone can help?
These are lichens and they generally do not cause a problem. See Algae, lichens and moss on trees and shrubs / RHS Gardening You didn't say what the plant is. You can post a photo of the whole plant and say what it is - maybe I'll move this posting again if we need to discuss the plant itself.
Agreed, your photo shows a few lichens, including in the foreground lovely wee Rosette lichen, likely Physcia adscendens or similar hooded species. In the background a couple Sunburst lichens, probably Xanthoria parietina but can't see enough details on those. These are not fruiting bodies of a fungus, and thus they are unrelated to the condition of the shrub.
