HYGEOPHOEUS. 347 



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

 distinguish from^ M. pratensis, with which it agrees in the 

 firm, short, stuffed stem atteniTated 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 S. pra- 

 tensis more especially by its small stature, constantly white 

 colour, 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.) 



Var. roseipes, Mass., in Cke.,Hdbk„ p. 295; Cke., Illustr., 

 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 IX. 



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 decurrent, 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 /j..

 p. 295 ; Cke., lUustr., pi. 900a. 



Among grass, moss, &c. 



More slender, tougher, hygrophanous, and appearing later 

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

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

 differing from H. russo-coriaceus. 



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

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

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

 smooth, rather viscid ; gills decurrent, li line broad, thick, 

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

 stem up to 1 in. long, 11-2 lines thick at the apex, which
