I see tree lichens and moss, which are not harmful, and usually grow in moist shade. I also see holes in the tree which can be from wood boring insects or birds trying to get sap. The black could be sooty mold growing on sap or insect honeydew. It also could be from bacterial diseases or canker. These articles should help decipher the problems:
