Dioicous ; in depressed subintricate tufts, lurid green or yellowish 

 above, fuscous or ferruginous below, rather rigid. Plants often much 

 elongated, prostrate and trailing, naked in the old parts, fasciculate- 

 branched, densely nodoso-ramulose. Leaves densely crowded, patulous, 

 curved upward and backward from an elongate ovate base, narrowly 

 lineal-lane, muticous, with the margin reflexed, plicate at base, faintly 

 papillose, nerve weak, ill defined, vanishing below apex ; cells all 

 elongated and sinuose, 2 — 4 rows at basal margin hyaline, quadrate. 

 Seta brownish-yellow, thick, calyptra almost wholly papillose, multifid 

 at base ; caps, oval or oblong, pachydermous, fuscous, black when old ; 

 lid acicular, shorter than caps., crenulate at base, annulus rather broad, 

 teeth purple, long, cleft to base into two filiform nodose legs, erecto- 

 patent when dry. Male plant more slender, with shorter leaves, bracts 

 of infl. broadly ovate, nerveless. 



Hab. — Rocks in subalpine districts. Fr. 3. 



Readily distinguished by the numerous lateral ramuli, and the perfectly 

 muticous leaves with thin nerve. It somewhat resembles G. aquatica, but 

 that species wants the short lateral ramuli, is more rigid with a thicker 

 nerve, and the upper cells of leaf are short and scarce sinuose.
