In the autumn I found a small bit of bark measuring 2 1/2 inches in length, on which was a cluster of bird's nest fungi. I took this home and the fungi has remained intact, a perfect little sculpture. Each "bird's nest" fungus is about 1/8 inch in diameter. You can see the "eggs" in one. In reality, the spore caps which release their spores when hit by raindrops. Two of the fungi have not opened.
