CLASSIFICATION 267 



/. sambucina. — Cap convex, then expanded, often wavy, silky- 

 fibrillose, nearly smooth and not cracking, white, often tinged 

 yellow, 2-3 in. across ; gills broad, whitish, then dingy ochre ; 

 stem stout, short, often curved, fibrillosely striate, white, i-il in. 

 long (spores elliptical, 9-12x6 /x ; cystidia ventriCose). 



A stout fungus, entirely white, cap often becoming yellowish 

 with age. L. sindonia differs in the narrow gills, stufted then 

 hollow stem, and smaller spores. 



In dry pine woods, etc. 



I. palUdipes. — Cap conico-campanulate, then expanded and um- 

 bonate, light brown, fibrose-squamose, disc innately scaly, edge 

 subrimose, about i in. across ; gills broadly attached, with a strong 

 decurrent tooth, becoming ventricose, scarcely crowded, rather 

 broad, pale cinnamon, edge paler and fimbriate ; stem slightly 

 narrower and mealy above, loosely fibrillose below, sub-bulbous 

 and with white down at the base, solid, \\'hite, 1-2 in. long (spores 

 pip-shaped, smooth, 8-9 X 5 ju. ; cystidia fusoid or subventricose, 

 numerous). 



Well marked by the white stem and the conico-campanulate cap. 

 First collected in this country at the Fungus Foray of the Essex 

 Field Club, in Epping Forest, October, 1910. 



On the ground in woods. 



/. corydalina. — Cap campanulate, then expanded, umbonate, 

 whitish with darker fibrils, umbo green, 1^-2 in. across ; gills 

 adnate, brown, edge white ; stem often curved, sub-bulbous, 

 whitish, pruinose, 3-4 in. long (spores elliptical, smooth, brown, 

 7-9x4-5 /x. ; cystidia ventricose, 42-57x15-18 jx). 



Easily known by the green umbo. . 



/. clarkii. — Cap bell-shaped, silky-fibrillose, whitish, about i in. 

 across ; gills rather distant, pallid, edge white ; stem solid, white, 

 1^-2 in. long (spores elliptical, 8-10 x 5-6 /x; cystidia ventricose, 

 scattered). 



AUied to I. sindonia, but differs in the sohd stem, persistently 

 pale gills and larger spores. 



On the ground in shady places. 



/. geophylla. — Cap conical, then expanded and umbonate, 

 minutely fibrillose, satiny and shining, often cracking, pure white, 

 sometimes tinged 3^ellow when old, about i in. across ; gills almost 

 free, rather broad, crowded, pale, then dingy clay-colour ; stem 

 satiny, white, often shghtly wavy, ii-2| in. long (spores elhptical, 

 7-9x4-5 /x ; cystidia ventricose). 



Smell earthy. Remarkable for its satiny appearance. Typically 

 pure white, but very variable in the colour of the cap, which ranges 

 from white, the most frequent condition, to yellow, lilac, violet, 

 tawny and brick-red.
