BURT — THELEPHORACE^ OF NORTH AMERICA. II 339 



11. C. delitescens Burt, n. sp. Plate 17. fig. 18. 

 Type: in Burt Herb. 



Fructifications gregarious, cespitose, somewhat fleshy; pileus 

 thin, convex, then umbilicate, dry, fibrillose, sepia-colored, the 

 margin inrolled; stem equal, solid, glabrous, chamois-colored; 

 hymenium even or sometimes obscurely lamelliform, chamois- 

 colored; spores white, even, broadly ovoid, 9 x 7 m, borne four 

 to a basidium. 



Fructification 10-15 mm. high; pileus 5 mm. broad; stem 

 10-15 m.m. long, 1 mm. thick. 



Growing among mos^s on vfery thin soil on rocks by water- 

 fall. Vermont. August. 



This species is intermediate between Cantharellus and Craterel- 

 lus in its hymenial structure, but, as some of the specimens have 

 the hymenium even and bearing mature spores, I include the 

 species in Craterellus. The specimens are much smaller than 

 those of C. calyculus and have the pileus becoming merely 

 umbilicate. The little fructifications were well concealed 

 among the mosses; I have found them but once. 



Specimens examined: 

 Vermont: Falls of Lana, Lake Dunmore, E. A. Burt, type.

Type: in Cornell Univ. Herb., 15445. 



Fructifications single, rarely gregarious, fleshy- membra- 

 naceous, entirely white when young, becoming pallid to ochra- 

 ceous buff with age, drying cinnamon buff; pileus narrowly 

 obconic, slightly viscid, the apex truncate, plane, or depressed 

 and with a thin margin which is erect or expanded; stem solid, 

 equal or tapering downward, flexuous, pruinose, with scattered 

 white hairs at the base; hymenium even, becoming longitudi- 

 nally rugose- wrinkled with age or upon drying; spores white, 

 even, subglobose, 3-4 m in diameter, borne four to a basidium. 



Fructifications 1-3 cm. high; pileus 4-9 mm. broad; stem f-2 

 cm. long, ^-1 mm. thick. 



On rotten twigs and leaves under prostrate branches of Taxus 

 canadensis. New York. October and November. 



This delicate fungus was under observation by Dr. Thom
