Autoicous ; in fragile tufts i 2 in. high, deep or yellow-green above, 

 fuscous below, resembling D. falcatum. Leaves falcato-secund, lanc.- 

 subulate, not crisped, entire or with a few minute teeth at apex, all 

 lower cells elongated, narrowly rectangular, upper shorter, the angular 

 very distinct, quadrate, brown, nerve narrow, excurrent. Perich. bracts 

 broad, sheathing, laxly areolate, suddenly subulate ; seta pale red, longer, 

 caps, oblongo-cylindric, gibbous and arcuate, strumose, striate when dry; 

 annulus double, lid conic, with a long oblique beak, peristome pale red. 



Male infl. close to perichaetium, inner bracts longly acuminate.
