Its thin pilens is "flexible at maturity. The silky sheen and regu 

 far pileus are quite characteristic. The cap has the color oi I looke's 

 figures of R. queletii Fr., />'. drimeia Cke. and /.'. purpurea Gill. 

 These three, including R. expallem Gill., have been placed together 

 by some modern authors as one species, characterized by "a 

 pruinose, violaceous, decolorate stem, and very sharp taste." The 

 taste is said to be so peppery that even when the color is washed 

 out by rains they can be recognized by this character. All of the 

 four are violet or reddish on the stem. <>m- specimens all bad a 

 white stem and an impeachable mild taste.
