While working out back I noticed all kinds of different things growing on the dead tree limbs that we were stacking in piles. The more I looked, the more interesting it became to see how many variations I could find. I have no idea what any of them are - except the second photo is your basic moss, I think. You need to click on the pictures to really see the textures and colors. They are all softer than they look. the first one is very delicate. Can you identify any of them? It would be fun to know what they are!
