ICONES MUSCORUM. 



The absence of deformity in its leaves, aside from other and 

 less obvious characters, at once distinguishes this species from 

 the preceding, the vernal form of which it much resembles. 



F. Lescurii is separated from F. squamosa (which has not 

 yet been found in this country, and the place of which it seems 

 here to supply) by its reddish stems, and bright green, fulvous, 

 glossy leaves, of a larger size and softer, as well as thinner tex- 

 ture ; smaller, cylindrical, thin-walled capsule ; imperfect inner 

 peristome ; and longer perichsetial leaves. 



F. Dalecarlica, compared with this species, is usually a lustre- 

 less, dark-green plant, having stems much more divided, branches 

 and branchlets longer, more slender, and subjulaceous ; leaves 

 rigid, smaller, and more crowded ; capsule shorter and very 

 thick-walled ; operculum depressed-conic ; teeth of peristome 

 lacunose along the axis between the fewer (15-16) articula- 

 tions ; and larger spores, about g^ (those of F. Lescurii being 

 only about j^nr) °f an i ncn m diameter. 



The spores of all the other American species yet found in fruit 

 are, like the spores of the European F. squamosa, of the same 

 size as those of F. Lescurii, except in the case of F. antipyretica, 

 where they are smaller, having a diameter of only about T ^^ of 

 an inch.
