Salix purpurea L. 



Low grounds. Albany and Bethlehem. An introduced willow, which has 

 run wild in some places. 



POTAMOGETON LONCHITIS Tuckm. 



Ticonderoga. Aug. 



LlSTERA AU&TRALIS Lindl. 



Lily Marsh, Oswego. Rev. H. Wibbe. This is an interesting addition 

 to our flora. 



POGONIA AFFINIS Aust. 



Fort Edward. Vandenburg. 



MUSCARI RACEMOSUM L. 



Wading River. Miller. A stray from cultivation. 



Eleocharis tricostata Torr. 



Wading River. Miller. This is probably the northern limit of this plant. 



WOODSIA HYPERBOREA Br. 



Crevices of rocks. Adirondack Mountains. Small forms of this fern 

 closely resemble W. glabella, and it is, perhaps, questionable whether they 

 should be regarded as two distinct species. In our specimens the chaffy 

 scales of W* hyperborea are present, but not in abundance. The specimens 

 were formerly referred to W. glabella. 



Arthonia polymorpha Aeh. 



Bark of trees. Geneseo. H. Willey. 



Graphis eulectra Tuckm. 



Bark of arbor-vitae. Newcomb, Essex county. Aug. 



Calicium brunneolum Aeh. 



Decaying balsam trunks. Mount Marcy. Aug. 



Calicium curtum Turn. & Bor. 



Decaying prostrate trunks of hemlock trees. Catskill Mountains. Sept. 



Chlorostylium cataractarum Kutz. 



Granite pebbles in running streams. Caledonia. Gf. W> Clinton. 



Sirosiphon Crameri Biugg. 



Wet surface of rocks. Mt. Marcy. Aug. 



Agaricus (Lepiota) cristatellus Pk. 



Pileus convex, subumbonate, minutely mealy, especially on the margin, 

 white, the disk slightly tinged with pink ; lamellsB close, rounded behind, 

 free, white ; stem slender, whitish, hollow ; spores subelliptical, .0002' * long. 



Plant about 1' high, pileus 2' '-4'' broad. 



Mossy places in woods. Copake, Columbia County. Oct. 

 The relationship of this very small species appears to be with A. cristatus. 

 The margin of the pileus is sometimes appendiculate with the minute frag- 

 ments of the veil. The annulus is obsolete. 



*One accent signifies inch or inches, two accents signify line or lines.
