The description is drawn entirely from American specimens: 
Autoicous, the antherida terminal on basal branches. Plants 
gregarious, pale green, slender, 10-15 mm. high; stems short, 
2-3 mm., leaves almost radical, rosulate, 2-3 mm. long, oblong- 
lanceolate, acuminate, vein thick, ending below the apex or ex- 
current into a cuspidate point; marginal cells elongated in two 
rows, entire or subserrulate at apex, lower cells elongated, often 
brown at angles; seta pale, slender, twisted, 10-13 mm. long, 
often bent ; capsules small, 1 mm. long, pyriform, becoming tur- 
binate when dry, with a broad flaring mouth, not contracted be- 
low it; neck tapering, often abruptly contracted when dry; 
mouth bordered by 4-7 rows of narrow cells, but slightly elon- 
gated or thickened, those of the walls smaller than in P. Zurbina- 
éum and rounded; annulus double, outer row orange colored, inner 
hyaline, vesicular, falling in fragments with the lid or persistent; 
lid blunt, conic or apiculate, bordered with orange; calyptra small 
2 mm. long, lobed; spores small, .014~.021 mm., spinose, yellow, 
ripe in May and June. 
Type locality in Switzerland. An uncommon species not yet 
reported east of the Alleghanies, ranging through the Central 
States both east and west of the Mississippi. Collected by H. 
J. Webber at Nebraska City, Nebraska, June 1, 1889; Argentine, 
Miss Reed, April and May, 1891; Cloud Co., W. A. Carlton; 
also Phillips Co., Kansas, Hatcher and Farm Ridge, La Salle Co., © 
Illinois, J. W. Huett. Also by E. Hall in Illinois, according to 
the Manual. 
Through the kindness of M. H. Philibert we have received a 
specimen supposed to be this species, collected by Gander near 
Lienz, in the Tyrol, in July, 1878. This is one of the specimens 
cited by Limpricht in his Laubmoose, but does not agree exactly 
with the description given by him, as the cells around the mouth, 
imstead of being in 1 I-15 rows, seem to be only six. We have also 
recently received from Dr. H. Solereder a duplicate specimen 
from the herbarium of the University at Munich, collected by 
Wienkamp near Wasam, in May, 1865. They also have only 
7-8 rows of cells around the mouth, and a narrow yellow annulus; 
the lid is short and blunt or truncate. The spores measure .024— 
©27mm., and are rough but not spinose. 
This rare species has only been distributed once in European 
“xsiccate and never in American ones, so that we have not much 
Material to guide us. Neither have we been able to see the speci-
