 368 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



II. 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 3|-4J m; hymenium concave, even, 

 pale ivory-yellow to cream color; spores colorless, even, pointed 

 at the base, 4-7 x 3-4 m; basidia clavate, 20 x 5m, 2-spored. 



Fructifications about | mm. high; J-J 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 B. & 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. LangloiSy 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 

 4-4 J fi, with four sterigmata; spores colorless, even, flattened on 

 one side, obovate, 7J x 4| ;u. 



Fructifications |-1 mm. broad. 



On dead prickle-bearing stems, possibly Ruhus sp. Wet 

 mountainous region at altitude 4500-5200 feet. Cinchona, 

 Jamaica. About January 1. 



This species does not appear closely related to any other
