214 Peck : New species of fungi 



Among 



Massachusetts. August 



1905. S. Davis. This is a peculiar and well-marked species, easily 

 recognized by its unusual colors, odor and habitat. The odor per- 

 sists several days after the plants have been collected ; its similar- 

 ity to that of a skunk has suggested its specific name. 



Collybia brunnescens 



Pileus thin, broadly convex, sometimes slightly umbonate, 



glabrous, subpruinose, grayish-brown ; lamellae thin, close, emar- 



ginate, whitish or cream-colored ; stem equal or slightly thickened 



at the base, striate, glabrous, solid or stuffed, white ; spores white, 



elliptic, 8-10 fi long, 5-6// broad. 



Pileus 2-7 cm. broad; stem 3-5 cm. long, 4-6 mm. thick. 



Solitary or cespitose in open places or in thin woods. Cali- 

 fornia. Mrs. C. A. Hunt. 



Sometimes the pileus is a little darker on the incurved margin 

 and its surface may be obscurely spotted. 



Hygrophorus Davisii 



Pileus convex, membranous, fragile, glabrous, very viscid, even 

 on the margin when young, striate when mature, olive-brown 

 variegated with olive-green when young and fresh ; lamellae thin, 

 unequal, distant, decurrent, grayish-white ; stem slender, equal or 

 slightly tapering upward, flexuous, fragile, hollow, viscid, glabrous, 

 grayish-white, becoming brownish ; spores broadly elliptic, white, 

 6-7 fi long, 4-5 ft broad. 



Pileus 1-1.2 cm. broad; stem 2-3 cm. long, 1.5-2 mm. thick. 



Damp places under ferns in deciduous woods. Stow, Mass- 

 achusetts. August, 1905. S. Davis. Gregarious. In the dried 

 specimens the whole plant has assumed a yellowish-buff color with 

 a faint tinge of pink. The pileus is sometimes slightly centrally de- 

 pressed. The species is dedicated to its discoverer. 



Russula nigrescentipes 



Pileus convex, nearly plane or centrally depressed, glabrous, 

 striate on the margin, bright-red, flesh white, taste mild ; lamellae 

 narrowed and united behind, much broader in front, close, equal, 

 free or nearly so, white ; stem equal, glabrous, stuffed or spongy 

 within, tough, elastic, white, becoming blackish by handling cr 

 bruising ; spores globose or subglobose, white, 6-8 fi in diameter. 



Pileus 3-5 cm. broad; stem 3-5 cm. long, 6-8 mm. thick.
