CLASSIFICATION 173 



H. clivalis. — Cap fragile, campanulate, then expanded and gib- 

 bous, irregular, edge incurved, wavy, smooth, even, opaque, becom- 

 ing polished and shining, dry, pallid, about i| in. across ; gills 

 adnexed, crowded, thick, fragile, whitish ; stem sohd, base nar- 

 rowed, often curved, fragile, smooth, mostly white, not more than 

 I in. long. 



Cap somewhat gibbous, not viscid. Differs from H. disians in the 

 gills being narrowed behind and nearly free. 



Among grass in damp places. 



Sub-genus III — Limacium 



* Cap white or becoming yellowish. 



H. chrysodon. — Cap convex, then plane, obtuse, viscid, white, 

 shining when dry, disc often tinged yellow and with minute ad- 

 pressed squamules, edge with yellow fibrils, 2-3 in. across ; gills 

 decurrent, distant, broad, thin, white, edge yellowish ; stem almost 

 equal, white with minute yellow squamules crowded near the top 

 in the form of a ring, 2-3 in. long. 



\^( Easily known by being entirely white, except the edge of the gills 

 and edge of cap, and upper part of stem, which are more or less 

 tinged lemon-yellow. 



On the ground in woods and open glades. 



H. melizeus. — Entirely straw-colour. Cap fleshy, convex, then 

 expanded or slightly depressed, smooth, even, viscid, edge thin, 

 ^2| in. across ; gills deeply decurrent, thin, distant, straight ; 

 stem slightly tapering downwards, soft, stuffed, apex with minute 

 white squamules, 2I-3 in. long. 



Almost exactly similar in build and size to H. eburneus ; differing 

 in being entirely straw-colour both outside and inside, and in having 

 a pleasant, spicy smell. Edge of the cap at first inturned and 

 downy, soon expanding and becoming naked. 



This species is probably passed over at times as a somewhat 

 slender, pale specimen of H. pratensis. 



Among grass in woods. 



H. eburneus. — Cap convex, then almost plane, even, viscid, edge 

 at first incurved and downy, soon naked, 1-2 in. across ; gills 

 decurrent, distant, firm, straight ; stem narrowed downwards, 

 viscid, rough at the apex with wart-like squamules, i|— 3 in. long. 



Resembling H. cossus in general appearance, but the colour is a 

 purer white, and the strong smell of H. cossus is absent. 



In woods. Gregarious. 



H. cossus.- — Cap convex, then plane, obtuse, glabrous, glutinous, 

 white with a yellow tinge, disc somewhat ochraceous, shining when 

 dry, 1-2 in. across ; gills adnato-decurrent, distant, connected by 

 veins, firm, white ; stem equal, white, rough with points above,
