96 TWENTY-SEVENTH REPORT ON THE STATE MUSEUM. 



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 lamellae 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. 



COPEINUS AQUATILIS 71. Sp. 



Pileus membranaceous, campanulate, sulcate-plicate 

 almost to the apex, furfuraceous, yellowish-brown ; lamellae 

 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 71. Sp. 



Pileus convex, soon expanded or centrally depressed, 

 umbonate, smooth, hygrophanus, chestnut-brown tinged 

 with violet, the margin whitened by silky fibrils; lamellae 

 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. 



Hygrophorus aurantiacoluteus B. & C. 



Among Dicranum. Sandlake and Albany. Aug. 



Gomphidius stillatus Strauss. 



Low mossy ground in woods. Adirondack Mts. Aug. 



Lactarius alpinus n. sp. 



Pileus fleshy, dry, umbilicate or centrally depressed, 

 tomentose-squamulose, ochraceous or tawny-yellow ; lamel- 

 lae close, yellowish-ochraceous ; stem sub equal, solid, 

 whitish or pallid ; milk white, unchangeable, taste acrid. . 



Plant about 2' high, pileus V broad, stem 2"-3" thick.
