    These are called fireflies and are generally the result of low amount of rendering samples. See https://blender.stackexchange.com/questions/1703/how-to-reduce-fireflies-in-cycles – Duarte Farrajota Ramos Jun 04 '17 at 17:47
  • Not an answer, but your node tree has a few problems: don't use an add shader for anything that are not shaders (green input should be connected to a green output), use the layer weight directly as a factor for the mix shader. The last Mix shader on the chain has an unplugged socket, what are you trying to achieve with it? –  Jun 04 '17 at 21:28

Please find the nodetree which solved the problem. I don`t know why it exactly works because try a lot and finally I removed the cast shadow of sun and the fireflies are gone. Sorry, for not more knowledge answer as beginner. Thanks a lot and have a great time Image
