In dry grassy places, on thatched roofs, but more especially 

 on sand-hills and sand-cliffs, etc. Not uncommon. Bearing 

 fruit, though rarely in early spring. 



Dioicous; forming whitish, shining tufts; branches few, 

 erect; leaves pointing every way, sulcate, ovate, strongly 

 acuminate, entire, more spreading when moist, nerve reaching 

 above halfway up ; fruitstalk even ; sporangium ovate, curved, 

 dark brown ; lid conical, acute.
