CLITOCYBE. 409 



It is possible that this form may be specifically distinct ; 

 but though it differs so much from the figure given by Gon- 

 nennan and Eabenhorst, the characters answer so well to 

 those which are given in Hym. Eur., that we do not consider 

 it at present distinct. It occurred on two occasions ; the 

 abrupt white apex of the stem is very remarkable. (B. and 

 Br.) 



The so-called variety only appears to differ from the 

 typical form in having the stem attenuated at the base. 



Clitocybe opiparia. Fr. 



Pileus 24 in. across, flesh thick, white ; convex then 

 plane, obtuse, even, glabrous, shining, yellowish red ; gills 

 slightly decurrent, crowded, whitish ; stem 2-3 in. long, 

 i in. and more thick, more or less equal, whitish, solid.

 Hdbk., p. 382; Cke., Illustr., pi. 1183. 



Among moss under trees, &c. 



Stem solid, fleshy, firm, not elastic, 2-3 in. and more long, 

 J 1 in. thick, equal or slightly attenuated at the base, 

 glabrous, white. Pileus fleshy, convex then expanded, 

 obtuse, 2-4 in. broad, even, at first with scattered fibrils, but 

 soon very glabrous, without a separate pellicle, becoming 

 pale but not hygrophanous, rosy flesh-colour, gilvous, or 

 fleshy tan-colour ; flesh compact, white, unchangeable. Gills 

 equally narrowed behind, acute, adnate or adnato-decurrent, 

 crowded, usually connected by transverse veins, 3-4 lines 

 broad, white. Smell not remarkable, taste pleasant. (Fries.) 



Clitocybe amara. Fr. 



Taste very bitter. Pileus l|-2i in. across, flesh rather 

 thick at the disc, margin thin, convex then plane, obtuse, or 

 sometimes slightly umbonate, dry, rufescent or yellowish 

 tawny, slightly flocculoee ; gills slightly decurrent, about 

 H line broad, crowded, white; stem about 2 in. long, 4-G 

 lines thick, tough, white, floccose then almost glabrous, solid ; 

 spores elliptical, 4 x 2 p..

 Cke., Hdbk., p. 47 ; Cke., Illustr., pi. 134A. 



In woody places. 



A very distinct species, but the variable colour of the 

 pileus is misleading. Varies to rufous-brown, whitish rufous,
