 in size. The brighter color of the smaller spores and the stuffed or 

 hollow smooth stem of our plant will separate it from this species. 

 Peck, Bull, of the Torrey Bot. Club, October, 1896. 



Cortinarius intrusus was a happy find. Several pints of it were col- 

 lected by the author in February usually a famine month for the 

 mycophagist. They grew on the ground, in beds among plants, and 

 with potted plants in a hot-house in Haddonfield, N. J. The crop con- 

 tinued well into the spring. The species is delicate, savory, and a most 

 accommodating renegade from its kind. I have never found it else- 

 where. 



** Gills bhie, then cinnamon. 



C. Cfierules cens Fr. Pileus 2-3 in. across, equally fleshy, convex 

 then plane, obtuse, regular, even, almost glabrous, but often fibrilloso- 

 streaked ; viscid, when dry shining or opaque, dingy yellow, almost 

 tan-colored, varying to yellowish-brown, etc. Grills slightly rounded 

 behind, adnexed, thin, closely crowded, 2 lines broad, at first clear 

 intense blue then becoming purplish, at length dingy cinnamon. Stem 

 about 2 in. long, % in. thick (bulb more than an inch), firm, equally 

 attenuated upward, at first fibrillose, bright violet, then becoming pale 

 and whitish, naked, bulb often disappearing with age; veil fibrillose, 

 fugacious. Spores elliptical, 9-10x5^. 



Amongst moss in woods, etc. 



Neither the gills nor the flesh change color when broken, a point 

 which distinguishes the present from C. purpurascens. When young 

 every part is generally blue. Smell scarcely any. Fries.

The American species seldom entirely loses the bluish-purple color 

 of its cap. The beautiful color fades somewhat or becomes splotched 

 with yellow. Neither does the bulb ordinarily disappear with age. It 

 is common. Taste of cap is mild, somewhat woody. They require 

 long, slow stewing, and are better made into patties and croquettes. 



C. purpuras'cens Fr. gills becoming purple when bruised. 

 Pileus 4-5 m - across, fleshy, disk compact, obtuse, wavy, variable,
