5. PHYSCOMITRIUM. Brid. 



Bry. univ. i, 97 (1826). 



Plants resembling Funaria. Calyptra small fugacious, mitrseform, 

 cleft, rostrate, covering only the upper half of capsule. Caps, sym- 

 metric, pyriform, lid from a slightly convex base, abruptly rostrate or 

 apiculate ; peristome none. Der. ^va-K-q a bladder, and /utTptov a 

 calyptra. 



For this genus of some 30 species, Lindberg retains the old title 

 Gymnostomum Hedw., but as that genus was simply a receptacle for ail the 

 mosses which had no peristome, I have preferred the later but more 

 definite title, as its most distinctive character depends on the inflated 

 lobulate calyptra.
