CLASSIFICATION OF AOAlUl 



Leal Gardens were white when drj . As these species occur so seldom 

 ;iinl far apart, it is difflcull to obtain exacl data « ith regard to their 

 characters. R.anomala Pk. and B. albidula differ in the acrid taste.

Gregarious. In woods of maple, yellow birch and hemlock of 

 northern Michigan. August. 



Pound in a number of places in considerable abundance. The 

 fragile character, especially of the gills, is very marked and the 

 mihl taste, white uills and red cap help to distinguish it. The 

 flesh does not turn so strongly ashy as in Peck's plants, ami this 

 character did not seem to be always noticeable. It is distinguished 

 from R. purpurina, the brilliant-red Russula, by its gregarious 

 habit. large size and less viscid cap; also the gills are doI crenulate. 

 (Mir specimens had the stature and appearance of /'. rugulosa and 

 /?. emetica var. gregaria. Peck's plants were found in Pennsylvania 

 by Dr. IlerhsF and reported but oner; the species is not included in 

 Peck's New York monograph. Our planl has so far been limited to 

 tie- north.
