AGARICUS CHIMONOPHILUS B. & Br. 
Vegetable mold or decaying wood lying on or half buried 
in damp earth Forestburgh. Sept. 
Our plant does not fully agree with the description of the 
species under which we have placed it. The lamelle are 
rounded behind, the spores are ferruginous-brown, and the 
pileus, which is often attached to the matrix by downy fila- 
ments, is frequently half an inch broad. Further investiga- 
tion may require its separation. 
CoPRINUS AQUATILIS 2. Sp. 
Pileus membranaceous, campanulate, sulcate-plicate 
almost to the apex, furfuraceous, yellowish-brown ; lamellz 
subdistant, reaching the stem, brownish then black; stem 
slender, equal, hollow, furfuraceous, whitish ; spores .0005’ 
long, .0003’ broad. 
‘Plant fragile, 2’-2.5’ high, pileus 6’’-8” broad. 
Sticks and twigs partly submerged or lying in wet mossy 
places. Adirondack Mts. Aug. (Plate 1, figs. 26-28.) 
The young plant is more yellow than the mature one. 
The species is related to C. silvaticus. 
CoRTINARIUS (HYGROCYBE) FUSCOVIOLACEUS 7%. Sp. 
Pileus convex, soon expanded or centrally depressed, 
umbonate, smooth, hygrophanus, chestnut-brown tinged 
with violet, the margin whitened by silky fibrils; lamelle 
at first plane then ventricose, rounded behind, rather dis- 
tant, dark-violaceous, becoming subcinnamon; stem flexu- 
ous, equal, solid, colored like the pileus, silky fibrillose. 
Plant 1’-1.5’ high, pileus 6-10” broad. 
Sphagnous marshes. Forestburgh. Sept.

GOMPHIDIUS STILLATUS Strauss. 
Low mossy ground in woods. Adirondack Mts. Ang. 
LacTARIUS ALPINUS 2. Sp.
