92 AGARICUS. 



Clitocybe. Protean, but the essential marks by which it can always be easily distin- 

 guished are these : odour none, stem pruinose at the apex, pileus convex (and 

 somewhat umbonate) then plane and depressed, gills cinereous-whitish. One 

 variety has the darker disc fuscous, another is flesh-coloured, another dingy- 

 rufescent (Batschf. 102).

185. A. pausiacus Fr. Pileus 2.5 cent, (i in.) broad, ciner- 

 eous, becoming somewhat olive, fleshy, thin, at first convex 

 (sometimes umbonate), then plane and depressed, even, smooth 

 (when young covered over with hoary silky dew). Stem 5-7.5 

 cent. (2-3 in.) long, 3 mm. (ij lin.) thick, tough, somewhat hol- 

 low, equal, striate and often undulated on the surface, smooth, 

 but white pruinose at the apex, cinereous. Gills very broad be- 

 hind and obtusely adnate, very crowded, semicircular, manifestly 

 inclining to olivaceous at every stage of growth. 



Odour weak, but frumentaceous. Allied to A. metachrous, but easily dis- 

 tinguished by its very broad and olivaceous gills. Intermediate between A. 

 metachrous and A. ditopus.

186. A. ditopus Fr. Pileus 5 cent. (2 in.) and more broad, 

 cinereous, somewhat fleshy, tough, at first convexo-plane and ob- 

 tuse, at length inverted, infundibuliform and often undulato- 

 lobed. Stem 5 cent. (2 in.) long, 6 mm. (3 lin.) and more thick, 

 hollow then compressed, equal, naked, pale cinereous, pubescent at 

 the base. Gills adnate, crowded, thin, at length turned upwards 

 and divergent in the lobes, dark cinereous. 



Its stature is that of A. metachrous, but it has a very strong odour of new 

 meal. Remarkable as compared with the rest for its toughness and irregular- 

 ity of form, and for being found only in a rotten condition in later autumn 

 when the rest are in fullest vigour.

187. A. diatretus Fr. Pileus slightly fleshy, tough, when
