 white milk that becomes lilac. Pileus 2-4 in. across, flesh 

 whitish, rather thin, loose ; plano-convex, unequal, somewhat 

 papillate then rather depressed, even, viscid, zoneless; gills 

 adnate, subdecurrent, rather crowded, about 1 line broad,

In damp meadows, &c. 



Distinguished from all other species by the presence of a 

 white, tomentose, deciduous silky zone near the margin of 

 the pilleus ; when this disappears the margin is very glabrous. 

 L. uvidus also has milk that turns lilac, but differs in the 

 broad gills and obsoletely zoned pileus.
