Myxacium amarum. 



Pileus thin, convex or nearly plane, often irregular, smooth, glu- 

 tinous, yellow, the disk often tinged with red, the margin whitish, 

 flesh white, taste very bitter ; lamellae close, rounded behind, whitish, 

 becoming ochraceous-cinnamon ; stem soft, viscid in wet weather, 

 solid, tapering upward, whitish, clothed with silky white fibrils ; 

 spores elliptical, .0003 to .0004 in. long, .0002 to .00025 broad. 



Plant gregarious or subcaespitose, 1 to 2 in. high, pileus about 1 

 in. broad, stem 2 to 4 lines thick. 



Under spruce and balsam trees. Adirondack mountains. August. 



The very bitter taste is suggestive of the specific name. The stem 

 is scarcely viscid except in wet weather. 



Russula compacta Frost MS. 



"Pileus white, firm, solid, cracked in age, sometimes tinged with 

 red or yellow or both in spots, turning up in age, seldom depressed ; 

 lamellae very white, almost free, not forked or dimidiate, becoming 

 brown when bruised or dry ; stem solid, white, even, smooth ; flesh 

 at first white, then brownish." 



Pileus fleshy, compact, convex or centrally depressed, whitish, 

 sometimes tinged with red or yellow, becoming reddish-alutaceous or 

 dingy-ochraceous with age, the margin thin, even, incurved when 

 young ; lamellae rather broad, subdistant, nearly free, some of them 

 forked, a few dimidiate, white, becoming brown with aire or where 

 bruised ; stem short, equal, firm, solid, white, changing color like the 

 pileus ; spores subglobose, nearly even, .00035 in. in diameter. 



Plant 2 to 4 in. high, pileus 3 to 5 in. broad, stem 8 to 12 lines 

 thick. 



Open woods. Sandlake and Brewerton. August and September. 



The late Mr. C. 0. Frost sent me specimens and manuscript descrip- 

 tions of a few species of fungi collected by him in Vermont. He gave 

 names to those which he considered new species, and it gives me 

 pleasure to adopt his names whenever it is rendered possible by the 

 discovery of the species within our limits. The plant here described 

 does not fully agree with his manuscript description, which I have 

 quoted, but it approaches so near an agreement that there cannot be 

 much doubt of the specific identity of the two plants. In our plant 

 the pileus is sometimes split on the margin. The change in the color 

 of the pileus and stem is nearly the same, but the lamellae sometimes 

 become darker than either. When drying, the specimens emit
