hyaline, small and quadrate above. Perich. bracts elongate, inner 

 longly sheathing, suddenly subulate ; seta yellow, capsule oblong, erect 

 slightly asymmetric, yellowish brown, lid conico-rostrate, yellow. 

 HAB. Trunks of trees and old rails ; very rare. Fr. 7 8. 



On decaying oak rails | mile from Abbot's Bromley, Stafford, sterile (Bloxam 1864) ! ! 



Intermediate between D. montanum and Scottii, and remarkable for the 

 great brittleness of the leaves. D. strictum, SCHLEICH, and fragilifolium, LINDB. 

 are also closely allied species. This plant may have been imported attached 

 to the wood on which it was found, and thus its very limited area accounted 

 for ; it is scattered sparingly throughout Central Europe from Sweden and 

 Finland to Italy.

Dioicous ; densely tufted, leaves patent, lane. -subulate, entire, not 

 crisped when dry, the nerve excurrent ; caps, elongate-elliptic, not 

 striate, lid obliquely rostrate, teeth short, nearly entire. (T. XXIII, E.)
