CLITOPILUS. 247 



round or compressed, scarcely 1 in. Ion*', 1-2 lines thick, 

 glabrous, base with white down ; spores subglobose, angular, 

 with an apiculus, 5-6 /x. 



Agaricus (Clitopilus) cancrimis, Fries, Epicr., p. 149; Cke., 

 Hdbk., p. 127; Cke., Illustr., pi. 501. 



Among grass, &c. 



Inodorous. A form is figured by Cooke differing from 

 the typical state in having a longer stem attenuated into a 

 slender, rooting base. 



** SERICELLI. 



Clitopilus carneo-albus. Wither. 



Pileus up to 1 in. across, convex then expanded, centre 

 becoming depressed and the margin drooping, even, polished, 

 white, the disc becoming usually tinged with rufous ; flesh 

 thin ; gills slightly decurrent, 1 line broad, crowded, salmon- 

 colour ; stem 1-1 J in. long, 1 line thick, about equal, solid, 

 white ; spores globose, nodulose, 7-8 fx diameter. 



Agaricus carneo-albus^ Withering, Arr., iv. 218 ; (not of 

 Fries) ; Cke., Hdbk., p. 128 ; Cke., Illustr., pi. 324b. 



On heaths, &c. 



Inodorous ; gregarious. Size and habit very similar to 

 Eccilia atro-puncta, but the colour is a purer white, and the 

 gills less decurrent. 



In the section given in Cke., Illustr., the stem is repre- 

 sented as being distinctly hollow. 



Clitopilus vilis. Fr. 



Pileus about 1 in. across, somewhat membranaceous, convex, 

 umbilicate, soft, grey, silky-fibrillose when dry, oj)aque ; 

 gills slightly decurrent or adnate with a decurrent tooth, 

 sometimes sinuate, almost triangular, crowded, whitish ; stem 

 hollow, 2-3 in. long, 1 line or a little more thick, equal, rather 

 rough, splitting in a fibrillose manner, colour of the pileus, 

 fibrillosely striate, base white, villous ; spores 7-8 X 6 /x. 



Agaricus (^Clitopilus) vilis, Fries, Epicr., p. 150 ; Cke., Hdbk., 

 p. 128 ; Cke., Illustr., pi. 487. 



Among grass, moss, &c., in open places. 



Resembling a Leptonia in the umbilicate pileus, but known 

 from that genus by the decurrent gills.
