a distinct pith." The gills are also often clouded. We 

 believe that all the specimens we have met with belong to one 

 species, and that this is the S. semiglobata recorded in Cooke's 

 Handbook (No. 313) for all the States. Taking everything 

 into consideration, we prefer to place the plants for the 

 present under S. stercoraria. 



Stems up to 4 inches high, hollow, with Whitish pith. 

 Pileus sometimes becoming brown. Spores 14 to 24 x 7 to 12 jx,

62. Stropharia umbonatescens, Peck: N. York State 

 Mus. Rep., 30, p. 41; Harper: Trans. Wise. Acad., etc., 

 xviii., p. 1023. — The following is the original description by 

 Peck, as quoted by E. T. Harper: — "Pileus at first conical, 

 subacute, then expanded and umbonate, smooth, viscid, 

 yellow, the umbo inclining to reddish. Lamellae plane, broad, 

 at length ventricose, blackish-brown with a slight olivaceous 

 tint. Stem equal, slender, hollow, generally a little paler 

 than the pileus. Spores purplish-brown, almost black, 10 x 15 

 to 18J ju,. Plant 3 to 4 inches high, pileus 6 to 12 lines 

 broad, dung in pastures." Harper, in reference to his speci- 

 mens, adds to the above description: — "The plants are very 

 close to Stropharia mammillata, Kalch., and probably belong 

 to that species, but the pileus is rather umbonate than 

 papillate, and the spores are elliptical rather than ovate or 

 pyramidal, as in the description of Stropharia mammillata." 



We refer the following (pi. ix., fig. 8) to S. 

 umbonatescens: — Pileus § to f inch in diameter, conico- 

 convex, then plane, acutely umbonate or papillate, yellowish- 

 brown with apex dark chestnut, very viscid. Gills adnate, 

 moderately distant, dark grey. Stem 3 to 4| inches high, 

 slender, fibrillosely squamulose below, hollow or partly filled 

 with spongy pith. Ring superior, evanescent. Marked 

 mouldy smell. Spores purplish, elliptical and somewhat 

 oblique or a little flattened on one side, 15*5 to 20 x 8"5 

 to 11'2 ix.
