Murrill: Dark-Spored Agarics 



129 



Pileus at first conic, subacute, then expanded and umbonate, 

 gregarious, 1-2.5 cm - broad ; surface smooth, glabrous, viscid, yel- 

 low, the umbo inclining to reddish; context thin, pallid, with a 

 fetid odor; lamellae adnate to slightly decurrent, crowded, plane, 

 broad, at length ventricose, whitish or gray to blackish-brown, with 

 a slight olivaceous tint ; spores ellipsoid, smooth, purplish-brown 

 under the microscope, 15-19 x io/*; stipe equal, slender, stuffed 

 to hollow, pallid with a yellowish tint, 5-10 cm. long; annulus 

 scanty, fugacious. 



Type locality : Schenevus, New York. 

 Habitat : On manure in pastures. 



Distribution : Massachusetts, New York, and Michigan ; prob- 

 ably also in Europe.

The real type of this species was collected at Schenevus. Cer- 

 tain other specimens so named at Albany are distinct. Sterling's 

 specimens are wrongly named ; Morris's, from Massachusetts, are 

 correct. Kauffman says it is not infrequent in Michigan, having 

 large spores and a rather fetid odor, and being near to 5". paradoxa 

 P. Henn. in shape. Harper suggests that it may be Stropharia 

 mammillata Kalchb., a species published in 1874. I have speci- 

 mens of this from Bresadola and they certainly look like our plant. 

 Manure-inhabiting fungi have a way of getting about and turning 

 up almost anywhere. 



4. Stropharia anellariformis sp. nov. 



Pileus thick, convex, obtuse, 2 cm. broad ; surface viscid, smooth, 

 not striate, pallid, pale-tan on the disk ; lamellae decurrent, sub- 

 distant, broad, pale-tan to fuscous, with a purplish tint; spores 

 broadly ellipsoid or ovoid, slightly apiculate, dark-purplish-brown 

 under the microscope, 9-10 x 7-8 /x; stipe subcylindric, larger to- 

 ward the apex, atomaceous above, fibrillose below, dry, solid, con- 

 colorous, 4-5 cm. long, 2-3 mm. thick; annulus persistent, distant 

 1 cm. from the pileus. 



Type locality : New Orleans, Louisiana. 

 Habitat : On manure. 



Distribution : Known only from the type locality.
