8-9 uw in diameter, highly mamillose on both sides and more or

Male plants unknown: in pale green to dusky green cushions 
with simple or slightly branching stems 2-3 cm. high; stem-leaves 
more or less crispate and tubulose when dry, erect-spreading when 
moist, the upper about 4 mm. long, linear-lingulate (or above 
often consisting of little more than the stout, very rough costa if 
bearing propagula), from a somewhat broader, ovate base, one 
fourth or more the entire length, with apex obtuse, often spiny- 
dentate, and border of leaf pale, irregularly dentate to spiny- 
dentate almost to the insertion of leaf; costa stout, 90-125 uw in 
diameter below, vanishing just below apex, very rough on back 
to below the cancellinae, with irregular, low, somewhat forking 
or spinose papillae; leaves in cross-section showing a terete costa 
with six or seven guide-cells, thick stereid bands above and below 
and differentiated outer cells, the leaf-blade mostly mamillose and 
finely papillose on upper side, papillose on under side, the margin 
a cylindrical band of minute, stereid cells extending from a little 
below the apex to near the cancellinae; cells of lamina variable, 
mostly roundish, obscure, 6-7 » in diameter in upper leaf to some- 
what pellucid and larger below, at least near the cancellinae; 
cancellinae either acute or somewhat rounded at apex, the cells 
toward costa broad, often nearly square; perichaetial leaves very 
similar to upper stem-leaves; seta erect, I-2 cm. long; capsule 
Ovate-cylindric, contracted at mouth, about 2 mm. long, with 
slender-beaked lid nearly as long; peristome-teeth short, lanceolate, 
obtuse, with two or three prominent articulations; calyptra de-
