strongly crisped: perianth oval to elongate-obovoid, 2-3.5 mm. 
5 mm., bistratose at base, the plicate mouth ciliate dentate : 
seta 5-12 mm. long; capsule subglobose, reddish-brown, .7—1 
mm. in diameter, the valves thick and rigid, of three layers of cells, 
the walls of the cells of the inner layers provided with very nu- 
merous annular or semiannular thickenings, those of the external 
layer with similar but much less perfect fibers ; spores cinnamon- 
brown, 13-15 м, minutely granulate-papillate ; elaters fusiform, 
80-145 и long, 8-10 м in greatest width, somewhat geniculate. 
On logs or decaying wood in moist places. Sisson, Siskiyou 
Co. (40, 41); near Mendocino (672); near Eureka (962). 
All our Californian specimens with the exception of no. 41 are 
sterile and gemmiferous, with the leaves mostly 2-,-less commonly 
3-lobed, otherwise subentire, the lobes, with rare exceptions, 
merely acute. Our no. 40, with leaves of this character, was once 
(Erythea, 4 : 49. 1896) erroneously referred to Jungermannia ven- 
tricosa Dicks., from which it may be readily distinguished by the 
more deeply and unequally lobed and more complicate leaves, the 
smaller dorsal lobe being often inclined forward somewhat parallel 
to the stem, and by the larger, thinner-walled leaf-cells. 
Our description of the sporogonium has been drawn from a 
Montana Specimen collected by Mr. R. S. Williams and from 
European material.
