Autoicous ; in bright green patches, with creeping subpinnate stems 

 and short erect branches. Stem-leaves erecto-patent, from a narrow 

 base, ovate, pointed, margin recurved at base, distantly serrulate, nerve 

 reaching f its length ; cells rectangular at base, narrow and elongated 

 above. Branch-leaves more or less complanate so as to appear in two 

 rows, often subsecund, narrowly ovato-lanceolate, more or less acuminate, 

 minutely serrate. Perich. bracts sheathing, ovato-lanceolate, suddenly 

 extended into a long serrated point, with a very slender nerve ; seta 

 reddish, smooth, capsule ovate-oblong, brownish, cernuous, strongly 

 contracted below mouth when dry, lid convex, rostrate, peristome yellow. 

 Male infl. small, the bracts nerveless. 



Hab. — On stones and trunks of trees, common. Fr. g — 10. 



A neat moss, varying little in habit, but the leaf points are sometimes 

 extended into a fine acumen, and occasionally are more or less obtuse. 

 When sterile it is liable to be taken for a small form of H. rutahulum, but with 

 fruit the smooth seta and rostrate lid at once distinguish it.
