 margined ; cells smaller, the upper narrower ; capsule larger, sub- 

 globose ; lid conic, without distinct beak ; calyptra unsymmetrical 

 bilobed with a long acumen ; pedicel long. 



Collected in May, 1875, and examined by Austin, who concluded it 

 was a large variety of P. pyriforme. Lesq. & James make no mention 

 of it. Eemarkably fine specimens were collected again in damp places 

 in meadows and pastures at Cedar Hill, near Victoria, Vancouver 

 Island, May 16th, 1887. (Macoun.) Also found in Oregon [Henderson
