 sometimes purple toward the base, prismatic, 3-6-angled, the 

 mouth somewhat constricted, denticulate or nearly entire ; invo- 

 lucral leaves larger, more or less connate, bifid, the lobes denticu- 

 late. Sporophyte an oblong-globose capsule on a short seta. 



On sand and rocks and occasionally on rotten wood, New 

 Jersey to Labrador, and on the Pacific coast from California
