72 Forty-first Annual Report on the 



short, hollow, silky -fibrillose, white, pale violaceous within; spores 

 broadly elliptical, .00024 to .0003 in. long, .0002 to .00024 broad. 



Pileus 8 to 12 lines broad; stem 5 to 8 lines long, 3 to 4 lines thick. 



Thin woods. Catskill mountains. September. 



Related to the preceding species, but smaller, with a hollow stem 

 and shorter spores. 



Cortinarius albidifolius, a. sp. 



Pileus thin, convex, subglabrous, whitish, tinged with yellow or pale 

 ochraceous, the ej^idermis sometimes cracking and forming squamules, 

 flesh whitish; lamellee subdistant, slightly emarginate, adnate, whitish, 

 becoming cinnamon; stem equal or slightly thickened at the base, 

 solid, white, variegated below with yellowish floccose squamules, 

 silky-fibrillose at the toj); sj)ores subglose or broadly elliptical; .00025 

 to .0003 in. long, .0002 to .00025 broad. 



Pileus 1 to 2 in. broad; stem 2 to 3 in. long, 2 to 4 lines thick. 



Woods. Catskill mountains. September. 



Related to G. ochroleucus, but apparently distinct by the yellow 

 scales of the stem and the adnate subdistant lamellae. Both it and 

 the preceding sj)ecies belong to the tribe Dermocybe. 



Cortinarius spilomeus, Fr. 



Woods. Catskill mountains. SejDtember. 



Cortinarius flavifolius, n. sjx 



Pileus convex or nearly jjlane, fibrillose or squamulose, sometimes 

 longitudinally rimose, varying in color troxjo. sordid buff to tawny yel- 

 low, flesh whitish; lamelli» subdistant, adnexed, at first a rich sulphur 

 yellow, then j-ellowish cinnamon; stem slightly tapering upward, 

 solid, whitish, peronate and slightly annulate by the copious silky, 

 whitish veil; spores broadly ellij)tical, .0003 in. long, .0002 broad. 



Pileus 2 to 3 in. broad; 'stem 2 to 3 in. long, 5 to 8 lines thick. 



Woods. Catskill mountains. September. 



The pileus is not truly hygrophanous, but the character of the stem' 

 indicates that the species belongs in Telamonia near C. bivelus. It 

 differs from C. limomus by its dry pileus, and from G. infucatus by the 

 color of the young lamellee. 



Cortinarius griseus, n. sp. 

 Pileus convex, obtuse or gibbous, fibrillose-sqiiamulose with grayish 

 hairs or fibrils, moist, pale gray; lamellre subdistant, adnexed, at first 

 pallid, then brownish-ochraceous; stem tapering upward from a
