Moss and lichens

I've been admiring how mossy, fern-y, and lichen-y (those are totally real words) everything is on this side of the state.  The trees are all bare right now but they have enough mosses and things growing on them that they still look dressed up.  These mosses are growing on a massive old stump behind our house.  It has a small tree growing out the top, some sort of shrub, ferns, and all these tiny things growing on it.  Back where it's dry, a stump mostly just looks like a stump, not a miniature forest.
