The Dicranunis have leaves that are narrowly to broadly lance- olate with lower cells rectangular, angular conspicuously dilated. The capsules are on straight erect setje, erect or inclined; teeth red, cleft half-way into two or occasionally three segments. (See Plate II). The Dicranums of our region are one of the most common and beautiful elements in woodland scenery. They are, for the most part, bright yellow-green and grow in wide thick tufts or mats. The leaves are fre- quently more or less se- cund, as though the wind had blown them all in one direction. They are com- mon on the ground, stones, rotten wood, and sometimes they occur on the base and trunks of trees. Most Dicranums mature their spores in autumn, but more obser- vations are needed to give exact dates for each Species. There are eighteen or twenty species of Dicra- num within our range, but only seven are common These seven are best treated in three groups. The first group contains two species with single curved capsules, the Broom Moss and the Fuscous Dicranum. The second group contains two species with curved clustered capsules and undulate leaves, the \\'avy Dicranum and Drum- mond's Dicranum. In the third group arc three species with single erect cap- sules, the Flagellate Dicranum, the Fulvous Dicranum, and the Long-leaved Dicranum. D. scopARiUM (L.) Hedw., the Broom Moss.
