11. C. Langloisii Burt, n. sp. Plate 19. fig. 6. 
Type: in Farlow Herb. and Burt Herb. 
Fructifications gregarious, membranaceous, cup-shaped, ses- 
sile, drying pale ivory-yellow, externally downy pubescent, the 
margin inrolled; hairs colorless, somewhat crinkled together, 
granular incrusted, 100-150 x 33-44 и; hymenium concave, even, 
pale ivory-yellow to cream color; spores colorless, even, pointed 
at the base, 4-7 x 3-4 u; basidia clavate, 20 x 5u, 2-spored. 
Fructifications about 1 mm. high; }-} mm. broad. 
On dead stems of Arundinaria and on decaying pieces of wood 
lying on the ground. Louisiana. September and April. 
The fructifications of C. Langloisii are about as small as those 
of C. minutissima but differ from them in being somewhat ex- 
tended laterally and occasionally somewhat laterally confluent 
rather than always globose, in having an ivory-yellow rather 
than snow-white color, and in having the hymenium colored 
and the hairs longer than in C. minutissima. Comparison should 
be made with C. fraxinicola В. & Br., of which I have studied no 
specimens but which seems distinct by some characters of the 
incomplete published description. 
Specimens examined: 
Louisiana: St. Martinville, A. B. Langlois, 1802, type (in Farlow 
Herb.), and cz, type, in Burt Herb., and cy, and from the 
same collector but comm. by W. G. Farlow, 5 (in Mo. 
Bot. Gard. Herb., 43791). 
12. C. porrigens Burt, n. sp. Plate 19. fig. 7. 
Type: in Burt Herb. and New York Bot. Gard. Herb. 
Fructifications scattered, membranaceous, thin, wholly cream- 
color, sessile, obversely cup-shaped or helmet-shaped, resupinate 
by the upper surface of one side but with the greater portion of 
the pileus extended and reflexed; hymenium inferior, somewhat 
wrinkled when moistened, concave, basidia clavate, 20-25 x 
4-44 y, with four sterigmata; spores colorless, even, flattened on 
one side, obovate, 73 x 44 y. 
Fructifications 1-1 mm. broad. 
On dead prickle-bearing stems, possibly Rubus sp. Wet 
mountainous region at altitude 4500-5200 feet. Cinchona, 
Jamaica. About January 1. 
This species does not appear closely related to any other
