when dried they changed to the characteristic cinnamon color of 
Dicranella heteromalla, with its twisted mouth and sulcate walls, 
and the pedicels became erect. These specimens grew at an 
elevation of 5678 ft. on the summit of White Top, Virginia, on 
rocky ledges in shade, and were in young fruiting stage on June 
26, 1892. Later in the same year, September 20th, I collected a 
few small plants in the trail up Mt. Marcy, in the Adirondack 
Mountains, New York. These also were small plants, with plump, 
ovoid, green capsules and yellow curved seta. But when dried 
the pedicels became erect, the capsules turned yellow, and showed 
unmistakably that they were only Dicranella heteromalla, It was 
also found at other points in the vicinity, usually in shade under 
or on the roots of trees in steep, sloping paths, often in very damp, 
black soil. Along the roadside, near the Lodge, the pedicels’ were 
seldom recurved, though the plants were small. In 1894 the form 
with recurved pedicels was very abundant both on Mt. Marcy and 
Mt. McIntyre, and formed large patches at considerable elevation 
on both these mountains. I had also collected it near Stowe, 
Vermont, in 1884, and been puzzled by the straightening of the 
pedicel in drying. In 1893 it was found growing with Dicrano- 
dontium longirostre on shady sandstone ledges of the Wisconsin 
: Dells, and it surprised me to learn from Dr. Barnes that it was 
the common form of Dicranella heteromalla in that vicinity. It 
has recently been sent to me by D. A. Burnett, collected in the 
Mountains of Pennsylvania on sandstone rocks at Bradford, asso- 
ciated with Dicranodontium longirostre, and it was collected in 
Similar habitat and the same association by Mr. D. A. Hopkins in 
West Virginia. We also have specimens collected by F. L. Har- 
vey in Maine, by Edwin Faxon on the bridle path at 3,500 feet 
elevation and on the summit of Mt. Lafayette ; also from the Lake of 
the Clouds on Mt. Washington. Pringle collected it on Mt. Mans- 
field, Vermont, and A. C. Waghorne in Newfoundland. I find 
three specimens collected by Austin in 1872 in the White Moun- 
tains, which had been sent to T. P. James for determination; ac- 
companying them is an autograph slip from James stating that 
they “ must be a Dicranum, but I do not make it subulatum.” 
Now it is a curious fact that Dicranella curvata, though re- 
Ported from two stations in North America, does not occur in any
