Hab. — On sandstone and calcareous rocks ; rare. 



Henfield, Sussex (Borrer) ! Ashley Mill, Cheshire [Dr. Wood). 



One of our commonest mosses and also a most variable one in -size of 

 leaf, seta and capsule ; the obtuse leaves with strongly recurved margins and 

 smooth white hair points are the most distinctive characters of the species. 

 The hair points are longest when the plants grow in dry exposed localities, 

 but this condition is hardly sufficient to constitute a distinct variety. 



13. TOETULA MUCRONATA (Brid.) Lindb. 



Dioicous ; tall, branched, deep green. Leaves elongato-lingulate, 

 papillose on both sides, mucronate with the stout nerve, suddenly 

 incrassate at margin. Caps, cylindraceous, lid with an oblique beak; 

 teeth on a narrow basal membrane, clathrate at base. (T. XXXII, A.)
