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. 



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

 and shorter spores. 



Cortinarius albidifolius, n. sp. 



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

 ochraceous, the epidermis sometimes cracking and forming squamules, 

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

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

 solid, white, variegated below with yellowish floccose squamules, 

 silky-fibriliose at the top; spores 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. 



Belated to C. ochroleucus, but apparently distinct by the yellow 

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

 the preceding species belong to the tribe Dermocybe. 



Cortinarius spilomeus, Fr. 



Woods. Catskill mountains. September. 



Cortinarius flavifolius, n. sp. 



Pileus convex or nearly plane, fibrillose or squamulose, sometimes 

 longitudinally rimose, varying in color from sordicf buff to tawny yel- 

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

 yellow, then yellowish cinnamon; stem slightly tapering upward, 

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

 whitish veil; spores broadly elliptical, .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 6'. bivelus. It 

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

 color of the young lamellse. 



Cortinarius griseus, n. sp. 

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

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

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