TERETIDENS gen. nov. 
Plants small, in loosely cespitose, pale green patches. 
Slender stems with distinct central strand. Leaves laxly 
spreading, nearly linear or lanceolate-linear with broad, 
rounded apex: costa not percurrent, in cross-section showing 
a distinct stereid band with a single row of large cells above 
and below: leaf-cells elongated-hexagonal, smooth, with 
walls often collapsing. Capsule oblong, with distinct collum 
about one third its length: peristome-teeth 32, erect, uni- 
more or less split upward around the base 
This genus of Pottiaceae (Pottieae) is evidently near 
Splachnobryum, but differs in having 32 distinct teeth, a 
well-defined collum, large annulus, rostrate lid and mitrate 
calyptra.

leaves similar to the perichaetial, but shorter. Stems more or 
less erect, branching, abouto.5 cm. high and 0.12 mm. indiam- 
eter: leaves but little wider toward base, up to 2.5 mm. long 
and 0.5 mm. wide, with rounded, serrulate apex ; leaf-margin 
flat, not bordered, serrulate about one third down; leaf-cells 
above very lax, hyaline, elongated rhomboidal to hexagonal, 
below longer, 20 # wide by 150 » long or more; costa about 
30 # wide at base and vanishing 3 or 4 cells or more below
