Pileus conic to campanulate, not expanding, rather thin, fleshy, 

 with a prominent, conic umbo, 1.5 cm. broad and high; surface 

 distinctly striate to the umbo, subglabrous, hygrophanous, um- 

 brinous to fuliginous, fulvous on the umbo ; margin straight, en- 

 tire, concolorous ;. lamellae broad, ventricose, distant, fuliginous, 

 concolorous and entire on the edges ; spores broadly and distinctly 

 ovoid, smo'oth, pale-purplish-brown under the microscope, about 

 5 X 3-5-4/*; stipe curved, equal, smooth, glabrous, fulvous, pallid

Type collected among moss in clay soil on a shaded bank at 

 Cinchona, Jamaica, 1,500 m. elevation, December 25-January 8, 

 1908-9, W. A. & Edna L. Murrill 575 (herb. N. Y. Bot. Gard.). 



18. Atylospora Roystoniae (Earle)
