They are undoubtedly this species as shown by the papillose 
calyptra and the reticulate spores, with the short immersed cap- 
sules, the antheridia in a basal bud and the subulate serrulate leaves. 
These being only manuscript names in Wilson’s Herbarium, do- 
not affect the question of the name, but Jeger’s published descrip- 
tions under the above names are not so easily disposed of.

Bruchia’ Caroline Aust. Bull. Torr. Bot. Club, 6: 144 (1877). 
Bruchia Ravenel Wils., var. mollis L. & J. Man. 49 (1884). 
Plants gregarious in brown patches, 1 mm., seldom 2 mm. 
high ; stems short, .5—1 mm. high, naked and radiculose at base; 
faves crowded at the summit, more or less secund, 1 rarely 2 
mm. long, subulate from a broader base; vein channeled, filling 
the entire or serrulate apex, faintly papillose on the back; basal 
cells smooth, irregular, upper with thickened: walls. Autoicous, 
the antheridia in brown basal buds. Seta shorter than the cap- 
sules, both immersed, or the capsules occasionally exserted later- 
ally, ‘S—75 mm. long, pyriform, yellow or brown, conic apiculate ; 
neck large, truncate, stomata immersed, the guard cells covered 
by the radiating cells around them; calyptra broad, lobed, papil- 
Ose at apex; spores small, .021~.027 mm., pitted, maturing in 
ebruary and March. ¢ 
Type locality, Aiken, South Carolina, H. W. Ravenel, 1872. 
Exsiccate: Austin Musci App. Supp. 461 (1878), also mixed 
with ZB. Drummondi, in Drummond's Southern Mosses, No. 16 
(1841), in our set; also with B. brevifolia in S. & I.. Musci Bor.

Differs from B. Raveneli in its pitted spores and smaller size, 
from B, brevifolia and B. fusca in its papillose calyptra and subu- 
late leaves, and from B. brevipes in its spores and calyptra. 
The types of this species are preserved in the herbarium of C. 
F. Austin at Columbia College. They have been compared with 
‘ype specimens of B. Ravenelii in Sullivant’s Herbarium and with 
Austin’s Specimens.of this species, as well as with No. 43 of Sull. 
& Lesq. Musci Bor, Am., Ed. IL. and Austin’s Musci App. No. 
460 and his description’ in the BuLLetin. The comparisons 
which he makes there are conclusive that these two must be held ag
