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.

    The glaucous appearance, shorter leaf base and very rudimentary endostome distinguish this from B microstoma.
