Bryum froudei, Kindb., Ott. Nat., Vol. V, p. 180. 



Habit of Webera nutans. Agrees with Hryum iiielinatum in the synoecious intlo- 

 resceuce and the symmetric cai)sule, etc.; differs in the leaves being Idng-acumiuate, 

 cells loug and narrow, the ujjper subliuear (uearly as iu Webera), costa very long- 

 excurreut, peristouiial segments (juite free from the teeth, spores smaller, scarcely 0.02 

 mm. ; the cilia are wanting.

Bryuni brachyneuron, Kindb., Ott. Nat., Vol. V, ]). 180. 



Agrees with Byrum pendulum in the synoecious inflorescence, the peristomes 

 orange, the segments adhering to the teeth, the apiculate lid and the l;irge spores 

 (about 0.04 mm.) ; diff"ers iu the decurreut leaves, short-ovate, the costa broad, abbre- 

 viate, not excurreut, the sterile shoots bearing globose buds (gemmae), the very much 

 broader peristoinial teeth. Stem red, very short, the pedicel about 1 cm. long or 

 shorter, often scarcely emerging above the tufts ; costa of the lowest leaves red, per- 

 current only iu the leaves of the shoots and the perichetial ones; capsule ventricose, 

 short-necked constricted below the mouth. Bryum fallax, Milde., resembling it in 

 habit, is dioecious; the segments are free, the spores smaller. Bryum lacustrc differs 

 in not having decurreut leaves, the cai)sule not being constricted below the mouth, the 

 pedicel longer, the i)eristome pale, etc.
