Bird's Nest fungus.

It is easy enough to see why these things are named "bird's-nest fungus".  One of my flower beds was filled with them last year and I brought this one in to see how well it would photograph.  The diameter of the fungi is about 1/4 inch and they typically like to grow on woody compost (at least in my garden).  If you are really bored, you can read about the exciting sex life of this species on Wayne's Word!
