Mosses. i74 MOSSES WITH A HAND-LENS mature in early spring. Frequent in swamps on the ground and over mosses. Although the plants are very distinct from every- thing else it is very difficult to get a drawing that represents them satisfactorily. PTILIDIUM. p. ciEiARE (L.) Nees also has its leaves divided into hairlike divisions, but a considerable portion of the base of the leaf is undivided. The plants are small, about of an inch wide, dark green, with leaves spreading when moist, closely imbri- cated when dry. The perianth is obovate with a fringed mouth. The spores ripen in early spring but the capsules may be found in autumn. The capsule in the illus- tration was collected in August. Ptilidium is very common on rotten wood and frequently occurs on humus and stones. It fruits very freely and the slender white setae surmounted by the black capsules are conspicuous objects to one who goes botaniz- ing in early spring. if ^ Figure 103. Ptilidium ciliare. a.

It is the tiniest of them all and looks more like a beautiful green alga than an hepatic. With the hand-lens the illustration will do more to help recognize it than volumes of description. It is very common on moist earth, stones and decaying wood and usually grows so far apart that the stems appear separate instead of forming mats. The spores mature in early spring, but the perianths are well formed in Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Grout, Abel Joel, 1867-.
