18. R. xerampelina Fr. Pileus 7.5 cent. (3 in.) and more 

 broad, rosy-purple, c., disc becoming pale, fleshy, compact, con- 

 vex then flattened, at length depressed, 'without a distinct pellicle, 

 wherefore always dry, opaque, even, but when older commonly 

 very thinly rimulose, so that the cuticle under a lens is very thinly 

 granulated or punctate, margin spreading, without striae ; flesh 

 compact, white inclining to yellowish. Stem 5-7.5 cent. (2-3 in.) 

 long, 2.5 cent, (i in.) thick, stout, firm, internally at length soft, 

 spongy, even hollow, commonly thickened at the base, even, 

 white or reddish. Gills adnexed, somewhat crowded, broader in 

 front, forked behind, whitish, then yellowish. 



Taste mild. The colour of the pileus is changeable, commonly rosy- 

 purple, with the disc becoming pale, yellowish-white, sometimes inclining to 

 olivaceous. The stem is redder when moist. It approaches R. integra, but 

 differs in the pileus not having a distinct pellicle, &c.
