Inocybe ageglutinata, n. sp. 
Pileus at first conical, then campanulate or convex, umbonate, fibril- 
lose, pale tawny, streaked or spotted with appressed fibrils, the umbo 
usually darker; lamelle 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 1 Whitei, but the umbonate dry pileus at 
once distinguishes it. The real affinity 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; lamelle 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 Velutine. It is distinguished from J. paludinella 
by its darker color, and its moist or subhygrophanous character. 
Inocybe vatricosa, F’. 
Damp ground under willows. Catskill*mountains. September. 
The pallid color, decumbent stem and 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.
