1896 | NEW MOSSES OF NORTH AMERICA 51 
Urora crispua Brid. var. dolosa.—Distinct from the genuine 
form by the dark green tint, the leaves less crispate and generally 
broader and the areolation less incrassate, the lower cells looser, 
shorter, hyaline or greenish, not yellow. 
District of Columbia: Tenallytown, mixed with Orthotrichum 
Ohioense and O. Braunit (J. M. Holzinger, 1892). 
This variety differs considerably from the type by its much 
looser basilar areolation, and would be easily taken for a well 
distinct species; but we have specimens, gathered at Atco, New 
Jersey, by Mr. H. A. Green, which are intermediate between this 
variety and the typical form. 
AMBLYODON DEALBATUS Pal. Beauv. var. AMERICANUS Ren. et 
Card. in Bull. de herb. Boissier 4:13. (Musci Am. Sept. Exsicce. no. 
180).—Differs from the European type by the segments of the 
endostome more subulate, nodulose and strongly granulose, and 
by the leaves more distinctly serrate above. 
Minnesota: Osceola, St. Croix river (J. M. Holzinger, 
1890). : 
PHILONOTIS VENELLA C. Muell. var. Coloradensis.—Areolation 
more chlorophyllose; marginal cells narrower, teeth of the leaves 
more patulous. Sterile-—Perhaps a small, depauperate form of 
Ph. Muehlenbergii Brid.? 
Colorado : Springdale, Boulder co. (Marie Holzinger, 1892 ; 
comm. J. M. Holzinger). 
ANOMOBRYUM FILIFORME Husn. var. Americanum,— Differs 
from the var. concinnatum (Bryum concinnatum Spr.) by the more 
slender and shorter stems, the smaller leaves and the shorter 
cells. Costa percurrent or vanishing just below the point. 
Sterile. 
Wisconsin : Trempealeau Mt. (¥. I. Holzinger, 1893). 
With Rev. Boulay, we consider Anomobryum filiforme ( Dicks.) 
Husn., 4. Jjuliforme Solms, A. sericeum De Lacroix and A. concin- 
“atum (Spr.) Husn. as belonging to the same specific type, 
which is widely distributed under numerous local or regional 
forms, throughout Europe, Africa, North, Central, and South 
America,
