11. G. COntorta, Bruch & Schimp. Plants of medium size 

 in loose soft green tufts, becoming black toward the base: 

 leaves incurved-spreading, crispate when dry, lanceolate toward 

 the base, linear-subulate, diaphanous at the apex or with a very 

 short hair-point, carinate-coucave and recurved on the borders 

 at base, complicate-carinate above, only the young ones green, 

 the others blackish brown ; cells of the areolation comparatively 

 large, quadrate, sinuous toward the apex, longer and hexagonal- 

 rectangular toward the base, partly chlorophyllose and partly 

 diajihanous ; perichaitial leaves sheathing at base, open and 

 subulate above : capsule oval, smooth, soft, small compared to 

 the size of the plants, inclined on a slightly arcuate pedicel ; 

 lid convex-conical, obtuse, erose at the base ; teeth bifid to 

 below the middle or lacunose, reddish brown ; annulus large, of 

 a triple row of cells. — Bryol. Eur. t. 248; Lesq. Mem. Cal.

Hab. Shade of the Big Trees, California {Bolaiider); sterile. 



The characters of the plants and leaves agree with the above descrip-

 shaped when moist, narrowly lanceolate-subulate ; costa stout, 

 vanishing below the apex; areolation long-quadrate or equi- 

 lateral at base, irregularly quadrate above ; perichaetial leaves 

 longer and longer acuminate-subulate : capsule oval, smooth,
