 mouth when dry, nearly smooth ; annulus none ; operculum 

 conic-rostrate, about 1 mm. long ; peristome-teeth shallowly in- 

 serted, orange-castaneous, non-striate but decidedly papillose, 

 strongly and rather densely trabeculate, the lamellae and di- 

 visural not very distinct, the teeth slender and often perforate 

 below ; segments usually longer than teeth, linear, arising from 

 a very nari'ow and often somewhat perforate basal membrane 

 which is usually inserted entirely below the rim of the urn, 

 the segments yellowish, granular-papillose, perforate-cleft in 

 a ladder-like manner along the median line ; cilia none, or 

 sometimes represented by mere stubs rising from the basal 

 membrane; exothecial cells heavily incrassate, castaneous- 

 pellucid, oblong, the upper rounded-quadrate, those at the rim 

 smaller and transversely oblong, darkly incrassate; spores 

 yellowish, minutely roughened, about .016-.018 mm., the walls 

 moderately incrassate. 



In damp, shady woods on rotten logs, stumps, wet soil, 

 rocks, etc., often in swamps. From New Brunswick to the 

 Carolinas and Alabama and west to the Rocky Mountain re- 

 gion. Not uncommon in our region but rather rarely found 

 in fruit.
