Order 2. Nidulariæ, the Bird’s-Nest Fungi
This is again divided into three genera. The Crucible (crucibulum), the Cup (Cyathus), the Bird’s-nest proper (Nidularia.)
We often find on a wood-pile or a fallen tree some of the members of the Bird’s-nest family. It is fascinating to examine them in their various stages of development. First we see a tiny buff knot, cottony in texture and closely covered; next, another rather larger, with its upper covering thrown aside, displaying the tiny eggs, which prompts one to look around for the miniature mother bird; then we find a nest empty with the fledglings flown. The characteristic that distinguishes the Bird’s-nest fungi from others consists in the fact that the spores are produced in small envelopes that do not split open, and which are enclosed in a common covering, called the peridium. One species is known by the fluted inside of the covering, which is quite beautiful. They are all small and grow in groups.
