often called Hypnum proper. Two of the most common ami 

 easily recognized mosses of this group are the Plume Moss 

 (Hypnum crista-castrttnsis L. ) and the Pinnate Hypnum (//. 

 impbnen$ Hedw ) The Plume Moss is common on decayed wood 

 and stumps in cool moist woods in New England and New York, 

 and probably throughout our range. A few starved specimens 

 have bt-en collected on Long Island. To be appreciated, this moss 

 should be seen in the cool moist recesses of the primeval moun- 

 tain forests, where it covers the fallen and decaying trunks of 

 huge trees with ample robes of richest texture. The shoots are 

 ascending and as regularly pinnate as any feather, even to the 

 triangular apex of the shoot. Its color is a light yellow-green.
