The'acumination of the leaves is much longer and more slender than that of L. brachypus and is also entire. The upper median cells are also usually a little more elongated. The secondary stems also much shorter than those of well developed Z, brachy- pus. Probably common in North-Eastern United States and Eastern Canada but not often collected or else confused with L. brachypus. Collectors should be on the lookout for it. In examining leaves for serration, several should be examined, as the leaves of Z. brachypics and L. julaceus are sometimes nearly entire. Leucodon brachypus Brid. Secondary stems averaging longer and larger than in the preceding species, less frequently branched. Leaves more strongly secund, plicate but with fewer folds than in L. sciuroides; the acumination is serrulate and not nearly so slender and pointed as in L. sciuroides. Seta 3-4mm. long, wrapped up in the perichaetial leaves, which over-top the emergent capsule; annulus lacking, teeth bifid at apex. Spores maturing in winter. Having about the same ranges as the last but extending farther south. Abundant and frequently fruiting in the mountain reg
