. Mosses with a hand-lens; a non-technical handbook of the more common and more easily recognized mosses of the north-eastern United States. Mosses. 40 MOSSES WITH A HAND-LENS. Figure is. Ceratodon purpureus X ^ and capsule . Leaves, calyptra, X 10. The leaves may be entire or slightly denticu- late at apex, and the costa is sometimes percurrent or even excurrent. The stems sometimes become three inches long in shaded places. When the capsules have fully matured they shrink when dry and be- come furrowed. This pe- culiar furrowing and the dark rich color of the capsules, a color called purple by the older bot- anists but which is really a very dark chestnut or red-brown, make it easy to recognize. The peristome is shown in Plate II. Aulacoinnhim pabistrc has a capsule furrowed in a similar manner, but it is easily distinguished by the characters noted under the description of that genus. TREMATODON Mx. T. AMBIGUUS (Hedw.) Hornsch., the Long-necked Moss, is so odd in appear- ance that it will need little description. It is not common, but will be met with occasionally in rather dry soil in copses and old fields where the grass is thin. Be- sides the long neck, the bright yellow setae, closely resembling those of Dit- riehum pallidum, are an additional aid in identification. The capsules mature in summer. T. LONGicoLUS Mx. is easily distinguished by its much longer neck, twice the length of the rest of the capsule, which is more cylindric than in T. ambiguus.
