thickened or bulbous base, silky-fibrillose, whitish; spores .0004 to 

 .0005 in. long-, .0003 broad. 



Pileus 1 to 3 in. broad; stem 2 to 3 in. long, 3 to 6 lines thick. 



Mossy ground under balsam trees. Wittenberg mountain. 

 September. 



The fibrils of the pileus are similar to those of C. paleaceus, but the 

 plant is much larger and stouter, and the spores are larger than in 

 that species. It is well marked by its grayish color. 



Cortinarius badius, n. sp. 



Pileus thin, at first conical, then convex or broadly campanulate, 

 umbonate, hygrophanous, blackish-chestnut color when moist, bay-red 

 or chestnut color when dry, sometimes tinged with gray, the umbo 

 darker, usually whitish-silky on the margin when young, flesh, when 

 moist, colored like the pileus; lamellse broad, subdistant, ventricose, 

 adnexed, at first yellowish or cream-color, then subochraceous ; stem 

 slender, equal, hollow, silky-fibrillose and subaunulate by the whitish 

 veil, when old colored like the pileua both without and within; spores 

 .0005 in. long, .0003 broad. 



Pileus 8 to 12 lines broad; stem 1 to 1.5 in. long, about 1 line thick. 



Mossy ground. Catskill mountains. September. ' 



The species is related to G. nigrellus, from which it differs in its 



broad lamellse which are paler in the young plant and in its larger 



spores. 



Cortinarius subflexipes, n. sp. 



Pileus thin, conical, then exj)anded and subacutely umbonate, 

 hygrophanous, blackish-brown with the thin margin whitened by the 

 veil when moist, subochraceous when dry; lamellae thin, close, ventri- 

 cose, adnexed, at first reddish-violaceous, then cinnamon; stem equal, 

 flexuous, silky, shining, subannulate by the whitish veil, pale 

 violaceous when young, jDallid or reddish when old; sjDores .00024 to 

 .0003 in. long; .0002 broad. 



Pileus 6 to 10 lines broad; stem 1 to 1.5 in. long, about 1 line thick. 



Thin woods. Catskill mountains. September. 



Apparently related to C. flexipes, from which I have separated it 

 because of its more glabroiis pileus and different lamellne. It and the 

 two pi'eceding species are referred to the tribe Telamonia. 



Cortinarius paleaceus, Fr. 



Mossy or bare ground in open places. Catskill mountains. Sep- 

 tember.
