394 THE AGARICACEAE OF MICHIGAN 



of C. ochroleucus, mentioned in "Monographia," p. 57, which is cont- 

 inued w ith C. sebaceoides as to stature and shown as an almost white 

 plant in Fries' figure at the Stockholm Museum. 



397. Cortinarius ochroleucus Fr. 



Syst. Myc, 1821. 



Illustrations: Cooke, 111., PL 775. 



Quelet, in Grevillea, Vol. V, PL 85, Fig. 1. 



"PILEUS 4-5 cm. broad, convex, gibbous and obtuse, even, gla- 

 brous or minutely silky, pallid-white. FLESH firm, white. GILLS 

 broader behind, adnexed, then seceding, crowded, whitish at first 

 then argillaceous-ochraceous. STEM 5-7 cm. long, 8-12 mm. thick, 

 solid, firm, ventricose, white, naked, except apex which is fibrillose 

 Iroin the cortina." SPORES (8x4-5 micr. Massee) rarely given. 

 "ODOR none. TASTE bitterish." 



The description given above has been adapted from Fries' "Mono- 

 graphia" and "Hymen. Europ." The species is occasionally re- 



1 »oiic(l from this country and is not well understood, not even in 

 Europe if we may take the meager notes into account. The figures 

 referred to have too much of an ochraceous color to agree with de- 

 scriptions. It seems to be rare as Fries has indicated, and its 

 medium size, ventricose or downward-tapering stem and bitterish 

 taste distinguish it from any American plants I have studied. 



398. Cortinarius sericipes Pk. 

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



"PILEUS 1-2.5 cm. broad, conical to subeampanulate, glabrous, 

 chestnut color, often darker on umbo. GILLS ascending or ven- 

 tricose, narrowed behind, broad, close, whitish at first, then tawny 

 to tawny cinnamon, white on edge. STEM 2-7 cm. long, slender, 



2 I nun. thick, equal, liollow, silky-fibrillose, slightly mealy at apex, 

 shining, white." SPORES almond-shaped, large, rough, 15-16x8-9 

 micr., ventricose, somewhat pointed at ends. 



"Damp ground in woods. New York. October." 



The type-specimens indicate a slender plant with the Inocybe 



habit. The spores were found to be narrower than given by Peck. 



The stem seems to have been subannulate by a white silky zone.
