CLITOCYBE. 407 



plane, somewhat utnbonate, and somewhat depressed ; gills 

 decurrent, very much crowded, narrow ; stem solid, downy. 



In larch plantations. 



Pileus 23 in. broad, stem l-l in. long, 2-3 lines thick. 

 Odour rather sweet, taste unpleasant. (Cooke.) 



Clitocybe polius. Fr. 



Pileus 1-2 in. across, flesh in. and more thick at the 

 disc, gradually thinning out towards the margin; convex 

 then plane, often obtusely gibbous especially when young, 

 glabrous, pale grey, not hygrophanous ; gills rather deeply 

 and equally decurrent, closely crowded, very narrow, white ; 

 stem 2-3 in. long, i in. or more thick at the base, slightly 

 attenuated upwards, glabrous, whitish, solid.

 Icon., p. 44, t. 48, fig. 1. 



Agaricus fumosus, var. polius, Cke., Hdbk., p. 52 (exclu. 

 syn., Saund. & Sin., t. 13). 



In woods. 



Caespitose, clusters sometimes small, at others consisting 

 of numerous individuals connate at the base ; the first con- 

 dition is the typical one, more regular, stem solid, rather 

 fleshy (not cartilaginous), equal, or slightly thickened at 

 the base, straight, glabrous, 2-3 in. long, white. Pileus 

 fleshy, orbicular, convex then flattened, 1 in. and more 

 broad, even, glabrous, pale grey, opaque, not hygrophanous. 

 Flesh white. Gills equally decurrent, very much crowded, 

 exceedingly narrow, quite entire, white. The second forms 

 luxuriant clusters of large size, stems very numerous, con- 

 nate at the base, thinner and often flexuous ; pileus thinner, 

 often irregular from mutual pressure. 



The superficial appearance and analogous form suggest 

 that the present species might be a form of Cfumosa, but 

 the structure is very different. C. polius is fleshy ; C. fumosa 

 somewhat cartilaginous, apex of stem pruinose, pileus at first 

 sooty then livid, somewhat hygrophanous; flesh hyaline, 

 whitish when dry. Gills irregularly decurrent, greyish- 

 white. (Fries.) 



Clitocybe inornata. Sow. 



Pileus 3-4 in. across, flesh thick, white; plane or de- 

 pressed, obtuse, even, smooth, cuticle separable, pale dingy
