when young, becoming brownish ferruginous; stem equal, firm, rather 

 long, solid or stuffed, sHghdy mealy at the top, white ; spores subelUptic, 

 pointed at one or both ends, .0005-.0006 of an inch long, ,00025-0003 

 broad. 



Pileus 1-2 inches broad; stem 1.5-3 inches long, 2-3 lines thick. 



Among fallen leaves in woods. Westport, October. This is related 

 to such species asH. elatius and H. longicaudum, from both 

 of which it is distinguished by its white color. The lamellae are not 

 serrate on the edge. 



Hebeloma albidulum n. sp. 



Pileus fleshy, firm, broadly convex or nearly plane, glabrous, slightly 

 viscid when moist, dingy white or grayish white, flesh white ; lamellae 

 close, narrow, adnexed, minutely denticulate and white on the edge, 

 whitish, becoming brownish ferruginous ; stem equal, firm, glabrous, 

 slightly mealy or pruinose at the top, sometimes slightly bulboiis, hollow, 

 colored like the pileus ; spores subelliptic, obtuse, .0004-. 0005 of an inch 

 long, .00024-. 0003 broad. 



Pileus 1-2.5 inches broad ; stem 1.5-2.5 inches long, 2-3 lines thick. 



Among fallen leaves in woods. Westport. October. This is closely 

 related to the preceding species. The pileus is not a clear white^ the 

 stem is hollow and the spores are a little darker in color and shorter and 

 more blunt at the ends. 



Naucoria firma n. sp. 



PLATK H, FIG. 10-16 



Pileus fleshy, firm, broadly convex, soon nearly plane, hygrophanous, 

 blackish brown when moist, ochraceous brown when dry, often rugulose, 

 flesh white, taste farinaceous, soon changing to bitter ; lamellae thin, 

 rather narrow, close, rounded behind, adnexed, pallid; stem firm, equal, 

 often flexuous or curved, stuffed or hollow, fibrillose striate and minutely 

 flocculose, colored like the pileus or a Httle paler; spores ellipdc, brown- 

 ish ferruginous, .0003 of an inch long, .0002 broad. 



Pileus 8-E2 lines broad; stem 1-2 inches long, 1-2 lines thick. 



Decaying, prostrate trunk of sugar maple. Floodwood. September. 

 This species has a firm texture and is quite regular in its mode of growth. 

 The only evidence of the presence of a veil is a slight pruinosity on the 

 margin of the young pileus. The lamellae are minutely white flocculose 

 on the edge.
