Murrill : Dark-Spored Agarics 277 



moist, dirty-white or clay-colored with a pinkish tint, subatoma- 

 ceous and radiately-rugose when dry ; context having a strong odor 

 resembling that of Sambucus pubens; lamellae crowded, broad, 

 attached, with a slight spurious decurrent tooth, dingy-flesh-colored, 

 then rosy-brown, finally black with whitish edges ; spores ellipsoid- 

 cymbiform, 9 /x long; stipe pallid, equal, hollow, slightly enlarged 

 at the base, slightly mealy and striate at the apex, subfibrillose 

 when young, 5-8 cm. long, 2-4 mm. thick. 



Type locality : West Albany, New York. 



Habitat : About manure heaps. 



Distribution : Known only from the type locality. 



The type specimens at Albany, collected by Peck in May, are 

 attached to a sheet and fairly well preserved. He seems to have 

 found it in quantity. Psilocybe atomatoides seems very close. 



16. Psathyrella distantifolia sp. nov. 



Pileus convex to expanded, becoming slightly depressed at the 

 center at times, solitary, about 3 cm. broad ; surface dry or slightly 

 hygrophanous, glabrous, conspicuously striate, dark-isabelline to 

 fuliginous ; lamellae adnate or sinuate, broad, distant, becoming 

 dark-fumosus to almost ater, whitish on the edges ; spores nar- 

 rowly-ellipsoid, sometimes apiculate, smooth, opaque, dark-bay un- 

 der the microscope, about 10 x 5^; stipe slender, equal, smooth, 

 white, glabrous, hollow, about 7 cm. long, 2-3 mm. thick. 



Type locality : Bronx Park, New York City. 

 Habitat : On loam in woods. 



Distribution : Known only from the type locality. 



The type specimens were collected by myself on September 10, 

 191 1, and a photograph taken of them. This species is rather near 

 Psilocybe atomatoides but the gills are more distant and the spores 

 larger and darker.

Agaricus graciloides Peck, Ann. Rep. N. Y. State Mus. 30: 42. 

 1878. 



Pileus thin, conic or campanulate, gregarious, 2.5 cm. broad ; 

 surface glabrous, hygrophanous, brown and striatulate when moist, 

 whitish and subrugulose when dry; lamellae ascending, rather 

 broad, subdistant, brown, becoming blackish-brown, whitish on the 

 edges; spores ellipsoid, blackish, 12-16 x 8-10 stipe long,
