expanded and gibbons, vAhite then pallid, grejdsli when dr}', 

 often mottled or with scale-like spots, margin naked; gills 

 slightly adnexed, much narrowed behind, broadest in 

 front, closely crowded, entire, white; stem ovately bulbous, 

 cylindrical above, l|-2 in. long, up to ^ in. thick, iibrillosely 

 striate, white, solid ; spores elliptical, 6-7 X 4 /x. 



Agaricus (Tricholoma) alhellus, Fries, Epicr., p. 43; Cke., 

 Hdbk., p. 38; Cke., Illustr., pi. 299. 



In woods, &c. 



Appearing earlier in the season than T. gamhosum, found 

 in April. Sometimes solitary, large ; sometimes densely 

 caespitose and smaller. Smell and taste pleasant, weak. 

 Pileus regular, not turning yellowish, white when fresh, 

 then grejish-brown, spotted here and there. Often con- 

 founded with a small form of A. gamhosus. (Fries.) 



T. gamhosum differs in the gills being attached by a 

 decurrent tooth; stem downy at the apex; the pileus is 

 usually very pale tan, but sometimes whitish. 



Tricholoma boreale. Fr. 



Pileus about 2 in. across, flesh thick at the disc and 

 becoming gradually thin towards the margin, soft, white ; 

 irregular, somewhat umbonate, glabrous, rivulose or minutely 

 downy when dry, flesh-colour then whitish; margin naked, 

 even ; gills emarginate, thin, crowded, white ; stem 2-3 in. 

 long, ^-| in. thick, solid, elastic, glabrous, unequal, at- 

 tenuated at the base, whitish ; spores subglobose, 4-5 /x, 

 diameter. 



Agaricus (Tricholoma) horeaUs, Fries, Epicr., p. 44; Cke., 

 Hdbk., p. 365; Cke., Illustr., pi. 950? (differing widely from 

 the figure and description of Fries in the very distant dingy 

 gills). 



Among grass in woods, &g. 



Truly gregarious, somewhat caespitose, smell resembling 

 new meal, taste pleasant, hence without doubt esculent, and 

 with allied forms may be compared with T. gamhosum. Stem 

 solid, elastic, 2-3 in. long, |- in. thick, attenuated downwards,, 

 often twisted and incurved, glabrous, apex indistinctly 

 pruinose, always white. Pileus fleshy, variable in form,. 

 usually convex and umbonate, unequal, often wavy, not 

 spotted, glabrous, minutely cracked when dry, about 2 in.
