Closely resembling jB. indusiata, but differing in its nearly smooth 

 shining seta. Peristome apparently composed of smooth bladdery cells, 

 scarcely free from the internal membrane. All the capsules yet seen, 

 although fully formed, are too immature to show the perfectly developed 

 peristome, or whether the external capsular wall rolls off as in B. indu- 

 siata.
