CoRTiNARius MUCiFLUUS Fr. (Myxacium). Infrequent, Tol- 

 land. Moist places under bushes. 



CoRTiNARius MULTIFORMIS Fr. Frequent, Leal. In troops, 

 under conifers. 



Cortinarius nigrocuspidatus sp. nov. (Telamonia). 



Pileus 2-3.5 (4.5) cm. broad, submembranous or slightly 

 fleshy, at first conic-campanulate, then campanulate-expanded 

 with an obtusely conical, black, prominent umbo, sometimes 

 mammillate, innately silky-fibrillose, silky-shining when dry, 

 glabrous, even, hygrophanous, "sepia" or "army brown" 

 (Ridg.) fading to "wood-brown" or paler, except umbo, 

 the margin at first decorated by narrow shreds of the white 

 universal veil; flesh thin, concolor, hygrophanous, fading. 

 Gills adnate, then emarginate with decurrent tooth, subdistant, 

 rather broad, ventricose, somewhat wrinkled on sides, at first 

 pallid-brownish, then "cinnamon" to "tawny-cinnamon." Stem 

 slender, 4-6 cm. long, 3-5 mm. thick, elastic, equal, flexuous, 

 stuffed, then hollow, "sepia" within and without, scarcely fus- 

 cescent, unequally zoned downwards by the silky white rem- 

 nants of the delicate universal veil, sometimes with only a median 

 zone. Odor and taste slightly of radish. Spores short ellipsoid 

 to suboval, 8-9 (10) x 5-6 ijl, obtuse, minutely and indistinctly 

 rough, rusty-brownish under microscope. 



Subcaespitose or gregarious. Leal, Colorado. Under spruce 

 and fir in mountain forests. 



Related to C. stemmatus Fr., from which it differs in its sub- 

 distant, broad gills, and somewhat larger spores. It has to some 

 extent the appearance of C. paleaceus, but the pileus is gla- 

 brous, and the spores larger. Sepia is the prevailing color in 

 fresh specimens; it is deeper and darker on the umbo of the 

 pileus. 



Cortinarius obtusus Fr. Frequent, Leal, Tolland. Caes- 

 pitose or gregarious, under fir and spruce. 



Cortinarius oricalchius Fr. (Bulbopodium). Infrequent, 

 Leal, Tolland. Under spruce and fir. 



This species seems to be sufficiently well known in Europe. 

 My Colorado collections were excellent examples of the species.
