its leaf apices and flagelliform branches. The secondary stems 

 are also much shorter than those of well developed L,. brachypus. 

 Probably common in Northeastern United States and Eastern 

 Canada, but not often collected or else confused with L,. brachy- 

 pus. Collectors should be on the lookout for it. 



L. BRACHYPUS Brid., the Northern Leucodon. The 

 branches average 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 apex is not nearly 

 so slender and pointed as in L. sciuroides. The seta is \ inch 

 long, wrapped up in the perichaetial leaves, which over-top the 

 emergent capsule ; teeth bifid at apex. The spores mature in winter. 



This has about the same range as the last, but extends far- 

 ther south. Abundant and frequently fruiting in the mountain 

 regions of Northeastern United States. It extends to Georgia 

 along the mountains, but is rare south of New York.
