Vcy small, gregarious, dirty green ; stems scarcely i — 2 mm 

 high. Leaves patent, subcirrate when dry, 1.25 — 1.75 mm. long, 

 and oblong-lingulate, obtuse, apiculate or crenulate by the pro- 

 jec'ion of the papillae; costa stout, percurrent or vanishing just 

 below the apex ; cells minute, rotundate orsubquadrate, densely 

 papillose, becoming gradually larger, oblong, rectangular, pel- 

 lucid and smooth toward the base. Perichetial leaves from an 

 oblong and loosely reticulate base, linear-lingulate, obtuse or 

 mucronate. Pedicel thin, reddish, paler above, 4 — 6 mm. long, 

 slightly twisted to the left under the capsule when dry. Capsule 

 small, erect, oblong-cylindrical, chestnut-colored, about i mm. 

 long. Lid unknown. Annulus simple, teeth of the peristome 

 purple, slightly twisting, on a narrow basilar membrane, seg- 

 ments filiform, minutely granulose, marked with a longitudinal 

 line, articulate, slightly nodose and partly connected in the lower 

 part. Probably dioecious (male flowers unseen). 



Resembling the smallest form of Barbula unguiculata, Hedw., 

 by the shape and areolation of the leaves, but well distinct by the 

 peristome being much shorter and less twisted, the teeth describ- 

 ing scarcely half a spiral turn. 



Newfoundland, 1895. {Waghome.)
