It isimpossible to ap-proach the subjectin its amplitude,but a concise ex-planation of the plate is necessary. This well-known moss cup is the sporangium,and in it are developed and contained the dust-likespores, protected by an elegantly perforated or re-ticulated tissue known as the peristome, which, insome cases, is capable of unfolding, revealing andreleasing the reproductive atoms within. The wholeis often covered with a calyptra, or hood—a looseextinguisher-shaped body which soon falls off; theperistome is then seen in all its beauty, when un-furled, as in Funaria, or as modified in other species,the spores escape and fulfil their function.
