402 FUXGUS-FLORA. 



Agaricus hullula, Briganti, t. IG, f. 1 ; Cke., Hdbk., p. 100 ; 

 Cke., Illustr., pi. 252b. 



On dead sticks. 



Somewhat resembling 0. infegrella, distingnislied by the 

 even, diaphanous pilens, and the broader gills. {Scattered. 



** 



Integrelli. 



Omphalia integrella. Pers. 



"White. Pilens 2-4 lines broad, membranaceous, conical 

 when yonng, soon hemispherical, often deformed, expanded, 

 disc depressed, then .V in. and more across, margin striate; 

 gills decnrrent, narrow, fold-like, distant, nsnally disappear- 

 ing within the margin of the pilens, equal or branched as in 

 Cantharellus, but with the margin acute ; stem up to 1 in. 

 long, slender, fistulose, rather firm, pilose below, base often 

 attached by a minute downy bulb. 



Agaricus (^Omphalici) iiitegrellus, Pers., Icon. Pict., t. 13, f . 5 ; 

 Cke., Hdbk., p. 100; Cke., Illustr., pi. 252c. 



On rotten wood, leaves, grass, and on damp ground in 

 shady places. 



Small, commonly fasciculate, especially when growing on 

 wood, w^hen the stem is incurved, fragile, variable in form, 

 entirely white. (Fries.) 



CLITOCYBE. Fries, (figs. 14, 15, p. 301.) 



Pileus generally fleshy at the disc, and becoming thin 

 towards the margin, flexible or tough, for the most part 

 piano-depressed or infundibuliform, margin involute ; gills 

 more or less decnrrent or adnate ; never sinuate ; stem 

 central, externally compactly fibrous, somewhat elastic, 

 stuffed, often becoming hollow ; veil either forming a downy 

 silkiness on the pileus, or obsolete ; spores elliptical or sub- 

 globose, smooth. 



Clitocyhe, Fries, Syst. Myc, i. p. 70 ; Cke., Hdbk., p. 45 

 (as a subgenus of Agaricus). 



Undoubtedly the most difficult genus, so far as the limita- 

 tion of species is concerned, that is included in the Agaricinae.
