Collected in August, 1908, on trees, at Sandy Cove, Nova Scotia, by 
Mrs. J. D. Lowe {iVo. 26 in part). Mrs.’ Lowe announced her discovery of 
this interesting species at the Baltimore meeting of the Sullivant Moss 
Society, in December, 1908, and has already published a note about it in the 
Bryoi.ogist for March, 1909. As she remarks, the North Carolina station, 
cited by Lindberg in 1875, belongs to another species. Her record, there- 
fore, is the first authentic one for North America. The type locality for the 
species is in Ireland but it is now known from numerous stations in western 
Europe. Mrs. Lowe’s specimens are entirely sterile but are quite sufficient 
for identification. 
The species is a very typical member of the genus Microlej eunea. 
The stems are sparingly and irregularly pinnate, with widely spreading 
branches, and average about 0.035 mm, in diameter. The leaves, which are 
distant to contiguous, spread very slightly from the axis and show a strongly 
arched keel. The lobe measures about 0.2 x 0.13 mm. and is ovate in out- 
line, the apex being either rounded or very bluntly pointed. It is attache^ 
by an almost longitudinal line and arches part way across the axis. The 
margin is either entire or vaguely crenulate from projecting cells. The 
lobule is relatively large, measuring about 0.15 xo. i mm. and is strongly 
inflated. It agrees with the lobe in being ovate in outline. The free margin 
is either involute or appressed to the lobe. At the apex it is tipped with a 
single cell in the form of a blunt, more or less curved tooth, and at the base 
of this tooth on the inner side is a slight depression in which a hyaline 
papilla is situated. The leaf-cells average from 16// to i8/< in length and 
about 14// in width. They are more or less convex and have thin walls, 
although minute trigones may usually be demonstrated. In many cases the 
cell structure is uniform throughout the lobe but sometimes one or two basal 
ocelli may be detected. When two are present they are situated end to end. 
The ocelli differ from ordinary cells in their more granular contents and 
are often difficult to distinguish. Similar ocelli occur sparingly in French 
specimens collected by Camus, but they are apparently absent in most of 
the European material examined by the writer. The underleaves of 
M. Alikina are distant and measure about 0.8 x 0.5 mm. They are ovate in 
outline and deeply bifid, the divisions being slender and pointed, usually 
four cells long, two cells wide at the base and tipped with two cells end to 
end.
