The greenish mold is lichen and is commonly seen on stressed plants. It will not harm the azalea but is merely a signal that something else is going on with the shrub. Here is more info: https://www.gardeningknowhow.com/ornamental/fungus-lichen/treatment-tree-lichen.htm

As for the black on the branches, it is most likely either sooty mold or sooty canker. Here is more information on these diseases:
