LEPTONIA. 255 



Leptonia chlo.ropolius. Tr. 



Pileus up to 1 in. across, membranaceous, convex then 

 expanded, striate, livid or yellowish-green, the disc with 

 blackish squamules ; gills narrowed behind and adnate, 

 pallid, then with a salmon-coloured tinge ; stem 2-3 in. long, 

 1^ line thick nearly equal, even, glabrous, greyish-green, 

 hollow ; spores elliptic -oblong, rough, 7-8 x 5 /i. 



Agaricus (Leptonia) chloropolius. Fries, Monogr., ii. p. 297 ; 

 Cke., lUustr., pi. 337; Cke., Hdbk., p. 131. 



Among grass in woods, &c. 



Similar to L. exilis in colour but differing in important 

 points, also resembling L. formosa in size and form, but differ- 

 ing in colour, stem rather firm, rigid, 2-3 in. long, 1 line 

 thick. Pileus 1 in. across, glabrous except the disc, margin 

 at first incurved. Grills 2 lines broad, margin similar in 

 colour. Agreeing in many points with L. asprella, of which 

 it may possibly be a variety, but the habit is different, and 

 no transitional forms have been seen, although both species 

 have been seen in quantities. (Fries.) 



Leptonia formosa. Fr. 



Pileus about 1 in. across, flesh thin, rather tough, convex 

 then plane, umbilicate, striate, waxy-yellow, more or less 

 covered with minute brownish or smoke-coloured, fibrillose 

 squamules; gills adnate, with a decurrent tooth, rather 

 distant, pale yellow, then flesh-colour, edge quite entire and 

 similar in colour, stem 2 in. long, about 1 line thick, equal, 

 even, glabrous, shining, yellow. 



Aaaricus (Leptonia) formosus, Fries, Epicr., p. 154 ; Cke., 

 Hdbk., p. 131. 



In woods, especially pine. 



Closely allied to L. asprella. The stem is sometimes 

 brownish or bluish. (Fries.) 



Var. suavis, Lasch, no. 285 ; Cke., Illustr., pi. 488. 



Pileus 1-2J in. across, convex then expanded, umbilicate, 

 fawn-colour, stem 3-4 in. long, 1-1| line thick, equal, pale 

 greyish-blue, gills broad, adnate, salmon-colour ; spores 

 subglobose, nodulose, 10 ft, diameter. 



In swampy places. 



It is doubtful whether the type form has occurred in 

 Britain.
