Hebeloma crustuliniforme, Bull. 



Open woods. Catskill mountains. September. 



A small form, but exhibiting well the characters of the species. 



Hebeloma longicaxidum, Pers. 

 Woods. Catskill mountains. September. 



In our plant the pilous is not umbonate, nor do all the descriptions 

 ascribe this character to the species. 



Flammula lubrica, Fr. 



Decayed wood and ground among fallen leaves. Catskill mount- 

 ains. September. 



This species closely resembles F. spumosa in general appearance, but 

 it may be distinguished by its somewhat spotted pileus and its white 

 flesh. The spores also are paler than those of F. spumosa. 



riammula subfulva, n. sp. 



Pileus convex, viscid, innately fibrillose, spotted toward the margin 

 with darker appressed scales, sordid-tawny, flesh grayish-white; lamellae 

 close, adnate, brownish-ochraceous; stem equal or slightly taper- 

 ing upward, fibrillose, solid, whitish; spores brownish-ochraceous, 

 elliptical, uninucleate, .00024 to 0003 in. long, .00016 broad. 



Pileus 1.5 to 2.5 in. broad; stem 2 to 3 in. long, 2 to 4 lines thick. 



About the base of trees. Catskill mountains. September. 



The plant is more or less csespitose. It is allied to F. spumosa, but 

 differs in its tawny squamose-spotted pileus and grayish-white flesh. 



Naucoria paludosa, n. sp. 



Pileus very thin, broadly convex or plane, glabrous, hygrophanous^ 

 brown and striatulate on the margin when moist, buff-yellow when 

 dry; lamellae close, thin, rather broad, adnexed, at first yellowish or 

 pallid, then brownish-ochraceous; stem slender, equal, hollow, brittle, 

 glabrous, pallid or brownish; spores ferruginous, elliptical, uninucle- 

 ate, .0004 in. long, .0002 broad. 



Pileus 6 to 12 lines broad; stem 1 to 2 in. long, .5 to 1 line thick. 



Wet, marshy or damp ground under willows and alders. Catskill 

 mountains. September. 



Naucoria unicolor, n. sp. 



Pileus thin, broadly convex, plane or slightly depressed, glabrous, 

 hygrophanous, yellowish-brown and striatulate on the margin when 

 moist, paler when drj^; lamellae thin, close, slightly rounded behind,
