On trees. Rare. Ireland ; Yorkshire. Bearing fruit in 

 spring. 



Forming little tufts or cushions. Leaves not papillose ; 

 leaf-cells rather large ; teeth of peristome yellow, recurved 

 when dry. 



Schimper asserts that this is not the true O. pumilum of 

 Swartz, and the names of O. pumilum aaAfallax were wrongly 

 applied in the ' Bryologia Europsea. 5 Swartz's plant (Moug. 

 & Nest. n. 925) has narrow cylindrical sporangia, while in 

 the plant before us they are swollen. 



6. O. tenellum, Bruch ; monoicous ; stems short, tufted ; 

 leaves spreading, loosely imbricated when dry, elongato-lan- 

 ceolate, rather obtuse ; veil rather long and narrow, with a 

 few hairs; sporangium exserted, oblong, widely striate. — 

 Hook. §■ Wils. t. xlv.

 ther wet or dry, elongato-lanceolate, strongly papillose ; mar- 

 gin reflexed; sporangium elliptico-oblong, with narrow striae;

 Wils. t. xxi. ; Eng. Bol. t. 1323. ; {Moug. % Nest. n. 323.)
