reuce to P. pyriforme (Rab. Krypta. 4 : Die Laubmoose, 2, 185. 1891). 

 Of the lid he says : « Deckel flach gewölbt, mit massig langer und 

 gerader Spitze. » Of the annulus « Ring zweireihig, gelbroth, gross- 

 zellig, stuckweise sich ablosend, » The spores are described as « Sporen 

 0,025-0,037 mm., rostbraun, dicht stachelig; reife im Mai. » 



M. Cardot questions the validity of P. Drummondü, and refers it to 

 P. turbinatum. We believe it is the nearest représentative we have in 

 America of P. pyriforme, on account of its long-beaked lid, but it 

 differs in not having the double annulus ; and the larger spores, warty 

 and not spinosely roughened, separate it as well from P. turbinatum.
