HYGROPHORUS. 347 



white colour of every part, but to me it is more difficult to 

 distinguish from H. pratensis, with which it agrees in the 

 firm, short, stuffed stem attenuated downwards, smooth and 

 naked externally ; pileus fleshy, convex then plane, at length 

 somewhat depressed, moist in damp weather; flesh some- 

 times equal, sometimes abruptly thin, striate ; gills de- 

 current, distant, rather thick. Distinguished from H. pra- 

 tensis more especially by its small stature, constantly white 

 coloiir, sometimes becoming pallid, pileus obtuse, scarcely 

 turbinate ; at length cracked in an areolate manner, and 

 floccose when dry, thin gills, &c. Certain individuals often 

 difficult to distinguish from allied species. (Fries.) 



Far. roseipes, Mass., in Cke., Hdbk,, p. 295 ; Cke., Ulustr., 

 pi. 893. Size of the typical form, differing in the stem soon 

 becoming hollow and rosy towards the base; spores pip- 

 shaped, 12 x 5-6 fi. 



In fir woods, &c. 



Hygrophorus (Camar.) niveus. Fr. 



Entirely white ; pileus -^1 in. across, almost membrana- 

 ceous, without a fleshy disc, hence truly umbilicate, cam- 

 panulate then convex, glabrous, striate and viscid when 

 moist, not cracked when dry ; flesh thin, everywhere equal, 

 white, hygrophanous. Gills Recurrent, distant, thin, scarcely 

 connected by veins, arcuate, quite entire ; stem hollow, equal, 

 2 in. or more long, 1-2 lines thick, straight, even, glabrous ; 

 spores elliptical, 7-8 x 4-5 //,. 



Hygrophorus niveus, Fries, Epicr., p. 327 ; Cke., Hdbk., 

 p. 295 ; Cke., Illustr., pi. 900A. 



Among grass, moss, &c. 



More slender, tougher, hygrophanous, and appearing later 

 in the season than H. virgineus. White, hygrophanous, 

 shining '.white when dry. Smell none, and in this respect 

 differing from H. russo-coriaceus. 



Hygrophorus (Camar.) russo-coriaceus. B & Br. 

 White ; fragrant. Pileus ^- in. across, persistently con- 

 vex, disc very fleshy, becoming very thin towards the margin, 

 smooth, rather viscid; gills decurrent, 1| line broad, thick, 

 very distant ; with shorter ones between, arched, white ; 

 stem up to 1 in. long, H-2 lines thick at the apex, which
