CLASSIFICATION OF AGARICS 



399. Cortinarius castanellus Pk. 

 N. V. State .Miis. Rep. 29, L878. 



PILEUS L-2.5 cm. broad, convex then expanded, umbonate, in- 

 nately silky, shining, glabrous, even, dark cinnamon to chestnut 

 color, iiiiiiio blackish, streaked blackish when old. FLESH thin, 

 pallid. GILLS adnate and rounded behind, then emarginate, close, 

 moderately broad, pallid, soon cinnamon-brown. STEM l •"> cm. 

 Long, 2-4 nun. thick, slender, equal or attenuated downwards, dingy 

 white then tinged fuscous, stuffed then hollow, glabrescent. SPORES 

 elliptical, rough, 7-9x L-.5-6 micr. 



Gregarious or subcaespitose. <>n bare ground "in open fields" 

 and borders of lakes. Ann Arbor. (Whitmore Lake.) October. 

 Infrequent. 



In color it resembles C. nigrellus Pk. bu1 that species is almost 

 twice as large, with a distind universal veil ami smaller spores. 

 It is a slender plant, reminding one of the Bydrocybes. 



400. Cortinarius basalis Pk. 

 N. Y. State Mus. Rep. 33, 1880. 



* 



"PILEUS L-2 cm. broad, convex then expanded, hairy, tawny, 

 FLESH thin. GILLS subventricose, pale tawny <ii first, cinnamon 

 when old. STEM 2-2.5 cm. long, 5-6 mm. thick, short, hollow, 



lilnillose. pallid or pale tawny, usually with a slight, wehhy annulus 

 below the middle of the stem.'* SPORES elliptical, smooth. 7 8.5 x 

 34 micr., pale under the microscope. 

 %, Xaked soil in woods. New Fork. Gaespitose, September." 



This seems to approach ('. impolitus in its hairy pileus and in 

 size and color, but that species has larger spores, hygrophanous 



pileus. shorter stem and grows in coniferous woods. The plants- are 

 small and tufted. It probably has pallid ijills when very young 

 since the change of color indicated by the description is very un- 

 usual.
