O, sPECiosuM Nees. Plate V. Perhaps the largest of our species, an 

 inch to an inch and a half in height, yellow-green above: leaves tapering, 

 very acute, papillose ; leaf cells very thick walled, the upper circular or ellip- 

 tical; calyptra large, hairy, companulate ; capsule oblong-cylindrical, almost 

 exserted, the upper leaves barely reaching the base, smooth or barely 

 marked with irregular ridges when dry; operculum rostellate ; peristome of 

 8 teeth, which when dry are recurved rather than reflexed, as the tip of the 

 tooth sometimes touches the capsule wall in a way to remind one of the 

 handle of a mug; segments 8, papillose. Like O. obtusifoliuin, this species 

 rarely occurs on rocks. The spores mature by October, but 1 have collected 

 operculate capsules in March.
