In low dense tufts or sometimes in thin mats with long creep- 

 ing stems and short subpinnate branches. Stem leaves 1.5 mm., 

 long by .04 mm. wide, narrowly ovate-lanceolate, about one-half 

 costate, serrulate all round, more or less decurrent and margin 

 reflexed near base, not very concave, and scarcely or not plicate. 

 Median leaf-cells linear, flexuous up to '065 mm. long, and "005 

 mm. wide. Alar cells short and broad, not forming a distinct 

 cluster. Branch leaves very similar to stem leaves but mostly a 

 a little smaller with longer costa ending in spine on back and ad- 

 jacent cells, sometimes papillose by the projecting upper ends. 

 Inner perichetial leaves pale ecostate, gradually narrowed to a 

 slender, flexuous, serrulate point, with rarely i or 2 coarse teeth 

 at its base. Capsule nodding, curved with lid about 2*5 mm. 

 long and i mm. broad. Lid conical its height about equal to 

 basal diameter. Annulus of two \ ows of cells. Teeth of peristome 

 hyaline bordered, papillose above, outer phtes striate, inner
