DISTINGUISHING FIELD-MARKS : This species resembles Z. can- 
phorata in size and color, but differs in the pileus becoming 
rimulose-areolate, in its fading to a more pinkish-terra-cotta when 
mature, or in any case as soon as collected, and in the thin bluish- 
white or watery milk. Тһе odor, which is very faint, does not 
become stronger in drying.
