Murrill: Agaricaceae of Tropical North America 31 
with minute, fulvous, conic elevations ; margin striate, dull- 
brownish in dried specimens, being very distinct in color from 
the remainder of the surface; attachment of pileus white, finely 
pubescent or slightly strigose ; lamellae broad, not crowded, slightly 
arcuate, cremeous to fulvous ; spores ovoid, smooth, dull-melleous, 
8-10 X 5-6^- 
Type collected on a small dead branch of a deciduous shrub on 
the Latimer trail, Cinchona, Jamaica, 5,000 ft. elevation, Decem- 
ber 25-January 8, 1908-9, W. A. & Edna L. Murrill jj6. Re- 
sembling C. calolepis, but with minute conic elevations instead of 
tomentose-scaly. 
16. Crepidotus substipitatus sp. nov. 
Pileus soft, fleshy, thin, very fragile when dry, orbicular-reni- 
form, expanded, gregarious, about i cm. broad ; surface moist, 
subglabrous, dull-ochraceous, not striate at the margin ; lamellae 
adnexed, subcrowded, rather broad, ventricose, ochraceous to 
dull-cinnamon ; spores ovoid or broadly ellipsoid, opaque, dull- 
cinnamon, minutely punctate, 5-6 X 4 stipe eccentric, short, 
curved, cylindric, glabrous, shining, dark-reddish-brown, 4-8 mm. 
long, i mm. thick. 
Type collected on dead twigs on the ground at the base of El 
Yunque, near Baracoa, Cuba, March, 1903, L. M. Underwood & 
F. S. Earle 12^6. When growing on the under side of sticks, the 
stipe curves so that the pileus appears resupinate. 
17. Crepidotus fumosifolius sp. nov. 
Pileus sessile, dimidiate or reniform, thin, firm, fleshy, expanded 
at maturity, scattered, 2-3 cm. broad; surface glabrous or slightly 
pruinose, whitish or with ochraceous tints, margin even; lamellae 
crowded narrow, becoming very dark- fuscous or almost purplish, 
resembling those of species of Hypholoma; spores ellipsoid or 
ovoid, dark-fuscous, 6-7X4j«- 
Type collected on a dead log on Rose Hill, Jamaica, 4,000 ft. 
elevation, October 30, 1902, F. S. Earle 2p2. An anomalous
