“In size and general aspect this moss resembles A. lapponicum 
and A. mougeotiz, but is distinguished by its broader leaf differ- 
ently areolated, and with a slight but evident constriction above its 
base.” Sullivant. 
Under overhanging rocks, Catskill Mountains, Greene county. 
This moss was found growing in a single patch three or four feet in 
diameter. The growth is quite dense, “the stems are s! :mple or fas- 
tigiately branched, mostly about one inch high; the leaves are 
numerous, closely imbricating, the upper ones yellowish green, the 
lower ones dull reddish brown, intermingled with a short, close, 
radicular tomentum, all linear ‘lanceolate, rather abruptly sharp 
pointed, slightly constricted above the base, more or less minutely 
papillose, densely areolated, the areole of the middle of the base 
oblong, towards the margins smaller and quadrate. The foliage is 
crisped when dry, erect-spreading when moist. It opens under th 
influence of moisture much more slowly than does that of A. lap- 
ponicum or of A. mougeotii. When moist the greater density of 
the foliage and the broader leaves give to the plant an appearance 
quite distinct from the two closely related species, which appearance 
enables it to be distinguished from them quite readily without a 
microscopic examination.

Exposed surfaces of rocks. Catskill Mountains. New to this 
country. The specimens are without fruit, and to that extent the 
species must remain in doubt.
