These are all images of the same species of moss growing on my garage roof. In its hydrated form it is fresh and vibrant with its leaves open as in the above image.
In these images it is dry to getting hydrated. It is quite amazing to watch how moss instantly gathers water when but a few drops are sprinkled on a dry mat of it. Within seconds it plumps up and begins to green or yellow up.
I believe the image below shows newly formed growth.
