DISTINGUISHING FIELD-MARKS: This specimen resembles 2. 
volema but differ in being zonate and more slender. Lloyd says 
of the specimens which he found: ‘Stem solid but slightly 
spongy, eccentric in the few specimens I saw.  Pileus brown, 
marked with zones. Milk white, acrid, not changing in color.” 
These specimens are in the herbarium of the N. Y. State Mu- 
seum at Albany. In the dried condition they resemble Z. /acti- 
Биа except for the zonation and their smaller size.
