173. A. vermicularis Fr. Pileus beautiful flesh-colour then ciitocybe. 

 tan-flesh-colour, fleshy, thin, umbilicato-convex then reflexed, in- 

 fundibuliform, undulato-lobed, even, smooth. Stem 5 cent. (2 



in.) long, 4 mm. (2 lin.) thick, hollow, equal, at length (soon} com- 

 pressed, smooth, shining, white, not Elastic, fragile rather. Gills 

 shortly decurrent, very crowded, thin, white. 



Gregarious, inodorous, somewhat fragile, moist in rainy weather, slightly 

 hygrophanous.

174. A. senilis Fr. Pileus 5 cent. (2 in.) and more broad, 

 dingy-tan, fleshy-membranaceous, flaccid, the disc depressed when 

 young, soon infundibuliform, smooth, concentrically full of scars, 

 margin spreading (not reflexed). Stem 4-5 cent. (1/^-2 in.) long, 

 4-6 mm. (2-3 lin.) thick, solid, equal, often ascending, smooth, 

 whitish, naked at the base. Gills deeply decurrent in a straight 

 line, linear, narrow, very crowded, at first whitish, then of the 

 same colour as the pileus. 



The colour is not easily described, of a dingy fuscous tan. Gregarious, 

 inodorous. It approaches A. flaccidus, though not in colour.

*** Pileus shining whitish, 



175. A. catinus Fr. Pileus 5 cent. (2 in.) broad, at first white, 

 in no wise hygrophanous, then passing into pale flesh-colour during 

 rain, and into tan-colour in dry weather, fleshy, moderately thin, 

 plane then infundibuliform, always obtuse, even, smooth; flesh 

 thin, flaccid, white. Stem 7.5 cent. (3 in.) long, 12 mm. (% in.) 

 thick, stuffed, internally spongy, elastic, tough, thickened and 

 tomentose at the base. Gills decurrent, straight, descending not 

 horizontal, broad, not much crowded, persistently white. 



The gills are broader than those of neighbouring species. The stem has 

 occurred equal. Allied to A. fiaccidus, and very much allied to A. infundi- 

 buliformis ; it is strongly scented with the pleasant odour of the latter, but is 

 singular in the colour being primarily wholly white, then flesh-colour during 

 rain, not becoming pale. For this reason it is analogous with A.phyllophilus, 

 which, however, is easily distinguished by its pileus never being infundibuliform , 

 by its thin stem, by its adnate gills, and by being inodorous.
