its cordlike strand of mycelium. This last character is unusual in 

 this genus and suggestive of the specific name. 



Leptonia transformata 



Pileus thin, submembranaceous, slightly convex or nearly plane, 

 often umbilicate, silky tomentose, dry or slightly moist in wet 

 weather, striatulate on the margin which is at first incurved, some- 

 times becoming wavy or split when old, white, flesh white, taste 

 farinaceous ; lamellae sinuate, adnexed, close, unequal, ventricose, 

 white becoming pink; stem long, slender, straight or flexuose, equal 

 or slightly narrowed upward, pruinose at the top, glabrous and 

 shining below, subcartilaginous, stuffed or hollow, white with a 

 white mycelium at the base ; spores flesh colored, angular, uninu- 

 cleate, .0004-.0005 of an inch long, .0003-. 00035 broad. 



Pileus 5-10 lines broad; stem 1-2 inches long, .5-1 line thick. 

 Bushy places. Falmouth, Mass. July. S. Davis. Both pileus 

 and stem become blackish or blackish brown in drying and the 

 pileus becomes deeply umbilicate and strongly striate from the 

 margin to the umbilicus. These changes give the dried plant an 

 appearance quite unlike that of the fresh one. 



Hygrophorus ruber 



Pileus thin, conic, commonly unexpanded, acute or subobtuse, 

 cuspidate or narrowly umbonate, very viscid or glutinous, bright 

 red, not turning black in drying; lamellae narrow, ascending, ad- 

 nexed, subdistant, yellow or yellowish brown ; stem equal, viscid, 

 hollow, colored like the pileus; spores subelliptic, .00024-.0003 of an 

 inch long, .00016-.0002 broad. 



Pileus .5-2 inches broad ; stem scarcely i inch long, i line thick. 

 Among mosses in wooded swamps. Ellis, Stow, Cohasset, Mass. 

 September. G. E. Morris. 



Distinct from H . c o n i c u s in its usually smaller size, more 

 viscid pileus, bright red stem and persistent unchanging color in 

 drying. 



Hygrophorus serotinus 



Pileus fleshy but thin, convex or nearly plane, often with the thin 

 margin curved upward, glabrous or with a few obscure innate 

 fibrils, reddish in the center, whitish on the margin, flesh white, 

 taste mild ; lamellae thin, subdistant, adnate or decurrent, white, the 

 interspaces slightly venose ; stem equal, stuffed or hollow, glabrous, 

 whitish ; spores white, elliptic, .0003 of an inch long, .0002 broad.
