Green dýjamosi moss
Don’t you just want to stick your head into that ice cold stream and take a big sip? Much of Iceland is covered with moss. This hyper green variant is called dýjamosi. It grows in extremely wet places like around waterfalls or in low lying marshy areas. The name literally means “bog moss” and you should never step into dýjamosi as you can be almost sure that you will sink into deep underlying mud. As you can see in the foreground of this picture, water often collects into large droplets on top of the moss. Also take a look at this picture where it the hyper green is in stark contrast with the black volcanic sand.
