Lecanora peltastictoides Hasse. n. sp. 
Thallus squamulose, whitish, squamules flattened-globular, thick, from 0.5 to 
1 mm. wide, pulverulent, radiately or variously fissured, KHO — , Ca(C10)2— . 
Apothecia solitary in squamules; disk at first small, depressed and dull black, 
later enlarging and occupying greater part of squamule, level with thalline 
margin, dark gray, moistened dull brick-red, from 0.25 mm. to 0.75 mm. wide 
with a thin gray proper margin. Epithecium sordid yellowish, subgranulose; 
thecium colorless; paraphyses coarse, septate; hypothecium colorless, about half 
the height of thecium; asci ovoid to saccate; spores ovoid or ovoid-ellipsoid 
simple, 2 to 6/z long, 7 to io^i thick. Staining blue with iodine. Gonidia 12 to 
20 n in diameter. 
On granite, Palm Springs. Type deposited in herb. Hasse. Differing from 
the externally very similar Acarospora peltasticta A. Zahlbr. in the pulverulence, 
less deep fissures, the minute areolae not so truncate; mature disk lighter in color 
and often pruinose, thallus has not the ivory-like appearance as in the Acarospora 
species.

NOTES ON THE DISTRIBUTION OF POLYTRIGHUM STRIGTUM AND 
SOME ASSOCIATED SPHAGNA 
E. J. Hill 
In the Bryologist for Sept. -Nov., 1910, O. E. Jennings writes of finding 
Polytrichum strictum Banks near Linesville, Crawford County, in the northwest 
corner of Pennsylvania, and comments on the southern location and low altitude 
of this station for a moss prevailingly of northern range, or when southern limited 
to alpine boggy regions. My experience with it has been of like character, it 
having been collected twice at a lower altitude than for the swamp in Crawford 
County, given as about 980 feet, but not quite so far south. In the summer 
of 1908 it was found in a tamarack swamp near Long Lake, in the vicinity of 
Fox Lake, Lake County, Illinois, the county at the northeastern corner of the 
state. It made dense hummocky cushions, closely associated with Sphagnum 
fuscum (Schimp.) Klingr., S. acutifolium, and A ulacom-nium palustre. The alti- 
titude of the station must fall below 800 feet, that of the railroad at Long Lake, 
into which the swamp is drained by a stream a couple of miles long and not of 
rapid flow, being 754 feet. The general altitude of the valley of Fox River, 
in which the lake is located, in its passage through Lake County is from 700-775 
feet. The latitude would place it about 75 miles or one degree farther north than 
that near Linesville, Pa. Several sphagnum swamps besides that near Long 
Lake are found in this part of the Fox River valley. 
The following year the Pglytrichum was again met with while collecting 
in Bergen Swamp, in Genesee County, N. Y., about 130 miles north of the station 
in Pennsylvania. The trees of the swamp are mainly arbor vitae, tamarack, 
and white pine. It is a sphagnum swamp and is botanically noted for the northern 
aspect of its flora. Here also the Polytrichum grew in hummocky cushions, in-
