Murrill : Agaricaceae of Tropical North America 75 



Type collected on the ground in moist woods at Rose Hill, 

 Jamaica, 1,200 m. elevation, October 30, 1902, F. S. Earle 28 J. 

 Known only from the type locality. This is one of the slender 

 species of the genus, with thin pileus, very narrow, crowded 

 lamellae, and slender stipe. It is not related, however, to Lepiota. 



3. Agaricus subsilvicola sp. nov. 



Pileus thin, expanded, solitary, 8 cm. broad; surface sub- 

 glabrous, moist or subviseid, smooth, not striate, fawn-colored 

 or pallid with reddish shades, darker on the disk ; margin entire, 

 concolorous ; context pallid with a reddish tint, the flavor peculiar, 

 subaromatic and unpleasant ; lamellae free, rather narrow, 

 crowded, dark-pink to brown ; spores ellipsoid, smooth, often in- 

 distinctly obliquely apiculate at the base, rather pale purplish- 

 brown with a yellowish tint under the microscope, 1-2-guttulate, 

 5 X 2.5-3 /a; stipe cylindric, slightly enlarged at the base, brownish 

 and silky above the annulus, whitish and fibrillose below, solid, 

 firm, tough, 8-10 cm. long, 8 mm. thick; annulus ample, white, 

 persistent, conspicuously floccose below, distant 1-2 cm. from the 

 apex of the stipe. 



Type collected at Cinchona, Jamaica, 1,500 m. elevation, No- 

 vember 2, 1902, F. S. Earle 380. Also collected on the ground in 

 moist woods at Rose Hill, Jamaica, 1,200 m. elevation, October 

 30, 1902, F. S. Earle 288. This species resembles Agaricus silvi- 

 cola in shape and size but differs somewhat in color, taste, etc., 

 and the spores are considerably smaller. 



4. Agaricus Johnstonii sp. nov. 



Pileus thin, convex to expanded, umbonate, becoming some- 

 what depressed with age, solitary or gregarious, 5-7 cm. broad; 

 surface dry, squamulose, brownish, darker brown on the rounded 

 umbo, becoming bay-brown throughout on drying ; margin entire, 

 concolorous; lamellae free, crowded, somewhat ventricose, dull- 

 chocolate-brown at maturity ; spores ellipsoid, smooth, indistinctly 

 obliquely papillate at the base, rather dark purplish-brown under 

 the microscope, 1-2-guttulate, 4.5 X2.5/A; stipe subcylindric, 

 slender, smooth, fibrous-stuffed, whitish, becoming brownish in 

 old specimens, 7-9 cm. long, 5-7 mm. thick; annulus prominent, 

 membranous, persistent, white, attached near the apex of the 

 stipe.
