CLASSIFICATION OF AGARK 263 



PILEUS L-2.5 cm. broad, conico-campanulate, at Length more or 

 less mammilately ombonate, with a viscid pellicle, pale ochraceous- 

 brownish or grayish on margin, umbo bright ochraceous brown to 

 reddish brown, even or obscurely Bubstriate, shining, glabrous. 

 FLESH thin, pallid. (JILLS adnate to adnate-decurrent, broad to 

 8ubtriangular } close, ;ii nrsl whitish then gray, anally purplish- 

 brown to blackish. STEM •"> in cm. Long, slender, equal, Btuffed 

 then hollow, toughish, i><t/n<i, Hh<i<iI ochraceous, covered ;it nrsl by 

 thin, obscure, scalj remnants of the veil ap to the fugacious \\- 

 NULUS. SPORES 17 L9 \ LO micr., elliptical, smooth, purple brown 

 under microscope, dark purplish in mass. ODOR often strong of 



niilish or foetid. 



Gregarious on dung hills or about manure heaps. September- 

 October. Ann Arbor. No1 infrequent. 



Much more slender and with a thinner, smaller cap than tin- two 

 preceding; also, the cap is very different in shape. Its rather foetid 

 odor and large spores distinguish it from others. It is close to 

 n. paradoxa P. Benn. in the shape of pileus and size of spores. 



Section II. Spintrigeri. Pileus without a distinct pellicle, 

 usually innately fibriUose, not viscid.

PILEUS 2-6 em. broad, rarely Larger, at lirsi globose-oval, then 

 convex-expanded, sometimes margin is elevated in age, Bilky-fibril- 

 lose, white then dingy, even, margin at times appendiculate. FLESH
