On bark at roots of trees, near Thomasville, Ga. Coll, by Mrs. A. P. 
Taylor, Oct. 20, 1905. Type in the herbarium of the author. Co-type in the 
Herbarium of Columbia University. 
The fruiting plants were few and closely intermingled with Raphidos- 
tegium adnatum. In order that perfect capsules might be left with the type 
as few peristomes as possible were studied. One of these seemed to have 
the teeth united at base in pairs. I am greatly indebted to Dr. G. N. Best 
for assistance in the study of this plant, although he is in no way responsible 
for this publication. He says that this plant has the capsules of Homalothe- 
ciella , and the leaves of Fabronia. No calyptra were found. 
As most of the available descriptions of B. subcapillata are inadequate, 
a fairly complete account of that species is appended to enable students to 
distinguish between the two.

Monoicous, in light-green, thin glossy mats; stems a few centimeters 
long, irregularly dividing, creeping, subpinnately branching: branches about 
5 mm. in length: branch leaves often somewhat homomalous, loosely imbri- 
cate, ovate to elliptical-oblong, .9-1.2x.3-3.5mm : abruptly long accuminate, 
more or less serrate above, smooth, concave; costa extending to middle 
or beyond: median cells linear-fusiform. 8-9 times as long as broad, 
quadrate alar cells about 10// wide, numerous, bordering the lower 1/4 of the 
leaf. Stem leaves ovate, short or long: acuminate, costa short or sometimes 4 
almost wanting; paraphyllia absent; antheridia large, obovoid, short stipi- 
tate, inner perigonial leaves ovate-lanceolate, concave, acute to acuminate, 
bordered by a row of narrow cells, nearly or quite ecostate. Perichaetium 
1.5mm. long, loosely sheathing, slightly spreading: inner leaves oblong to 
oblong-spatulate. gradually long-acuminate, serrate above, short costate, 
loosely areolate, leaf cells at base rectangular to rhomboidal : paraphyses 
unusually long and numerous. Seta about icm. long, rough twisted to the 
right: calyptra cucullate. hairy; capsule brown suberect to horizontal, gib- 
bous to slightly curved, with a narrow mouth, slightly constricted under the 
mouth, and lightly striate when dry and empty, 1.7 mm. long, length 2-3 
times the diameter: operculum convex-conic, rostrate: collumella apparently 
not persistent; annulus none; peristome double; the teeth linear-lanceolate, 
united at base, brownish-yellow, closely and regularly articulate, hyaline
