Leaves loosely to +- rigidly erect, with non-brittle tips, 3-3.5 mm long, abruptly narrow-lanceolate from an obovate, sheathing base; margins plane or narrowly revolute, serrate above the shoulders, with teeth paired, close-set, and large, especially above; costa excurrent; upper cells quadrate to rectangular, up to 20 µm long, 4-5 µm wide, obscure, papillose at the ends; inner basal cells laxer, linear, up to 80 µm long, 10 µm wide, those at the margin of shoulders hyaline, with thin but firm walls. Synoicous. Setae straight, 8-9 mm long; capsules suberect, 1.5 mm long, subglobose, furrowed; operculum convex, shortly and bluntly pointed; exostome teeth 150 µm long, faintly papillose, sometimes perforated below; endostome rudimentary.

Discussion
Fig. 430 i-1
B. glauca Lor., Moosstud. 160. 1864.
The glaucous appearance, shorter leaf base and very rudimentary endostome distinguish this from B microstoma.
