Inocybe agglutinata, n. sp. 



Pileus at first conical, then campaniilate or convex, umbonate, fibril- 

 lose, pale tawny, streaked or spotted with appressed fibrils, the umbo 

 usually darker; lamellae close, broad, ventricose, adnexed, at first 

 whitish, then brownish-cinnamon, often white on the edge ; stem firm, 

 solid, white or whitish and pruinose above, brownish or tawny and 

 fibrillose below; spores even, .0004 to .00045 in. long, .0002 to .00024 

 broad. 



Pileus 6 to 12 lines broad; stem 1 to 2 in. long, 1 to 2 lines thick. 

 Under pine trees. Catskill mountains. September. 



This is a beautiful and well marked species. The fibrils of the 

 pileus appear as if agglutinated to its surface, though it is not viscid. 

 Sometimes they form tawny spots like appressed scales. In very wet 

 weather they are apt to wash away and disappear. In general appear- ■ 

 ance the plant resembles /. Whitei, but the umbonate dry pileus at 

 once distinguishes it. The real afiinity is with /. geophylla. 



Inocybe nigridisca, n. sp. 



Pileus thin, at first convex, then nearly plane or somewhat centrally 

 depressed, umbonate, moist, minutely fibrillose, blackish-brown with a 

 grayish margin when moist, cinereous when dry; lamellae close, 

 rounded behind, free or slightly adnexed, at first grayish, then ferru- 

 ginous-brown, sometimes tinged with yellow; stem slender, firm, solid, 

 flexuous, minutely villose-pruinose, reddish-brown; spores nodulose, 

 .0003 in. long, .0002 broad. 



Pileus 4 to 8 lines broad; stem 1 to 1.5 in. long, .5 line thick. 



Under cinnamon fern, Osmunda cinnamomea. Kasoag. Oswego 

 county. June. 



The adornment of the pileus and stem is so minute that at first sight 

 the plant appears to be glabrous. The margin of the pileus soon 

 becomes elevated, causing the center to appear depressed. The spe- 

 cies belongs to the Velutinae. It is distinguished from /. paludinella 

 by its darker color, and its moist or subhygrophanous character. 



Inocybe vatricosa, Fr. 



Damp ground under willows. Catskill mountains. September. 



The pallid color, decumbent stem aiid webby veil are characteristic 

 of this species. The European plant is said to be inodorous, but our 

 specimens had a radish-like odor. In it the spores are even, elliptical, 

 .0004 in. long, .00024 broad. I find no description of the spores of the 

 European plant. A variety with the disk reddish occurs in the same 

 locality. It appears somewhat like a diminutive form of Hebeloma 

 longicaudum.
