Dioicous ; in loose dark green tufts, fuscescent at base, laxly 

 interwoven with radicles and with hyaline paraphysiform hairs in the 

 axils of the upper leaves. Leaves soft, scarcely sheathing cirrato- 

 crispate when dry, the upper long erect, yellowish-green, from an 

 indistinctly sheathing yellow base, with a band of fragile hyaline cells at 

 the insertion to the stem, gradually lineal-lanceolate, erecto-patent, 

 short pointed, convolute-concave, shortly serrate in upper half of 

 margin, indistinctly so below, cells in the lower half of leaf coarsely 

 papillose at back, rectangular, upper hexagono-quadrate and papillose 

 in front, nerve strong, reddish. Caps, horizontal, longish oval, lid 

 reddish-yellow, with a very small point, inner peristome without

Fine showy mosses growing in damp shady ground, and under 

 mountain rocks, usually innovating from the base of stem. Leaves 

 large, especially in the coma, ovate, elliptic or spatulate ; frequently with 

 a thickened serrated limb, the cells parenchymatous, incrassate smooth. 

 Capsule on a long rigid seta, pendulous or horizontal, oval, regular, 

 calyptra small cucullate, peristome of 16 lanceolate cuspidate teeth, 

 trabeculate externally, lamellose internally, endostome processes as long 

 as peristome with 2 — 4 nodose cilia. Male infl. discoid with clavate 

 paraphyses. — Der. f^viov a moss. 



About 50 species of this fine genus have been described, the greater part 

 of which are natives of the north temperate zone. The peristome and 

 endostome are both highly developed, and resemble those of the section
