 cells ; stomata numerous, immersed, with elevated border - cells. 

 Calyptra naked or nearly so, campanulate, thin, greenish-yellow, brown 

 at point. 8-plicate; lid short, conical. Peristome pale yellow, of 

 16 geminate teeth more or less cleft at point, papillose, long, recurved 

 when dry, cilia 16, filiform, hyaline, papillose. Male infl. terminal on a

This little moss is easily overlooked, as it only grows in small tufts, and 

 somewhat sporadically ; it may be recognized at once by the hyaline points 

 to the leaves. 



** Peristome teeth striolate, with erect vertical lamellae at base ; cilia none or rudimentary.
